Adolescence has been identified as a particularly vulnerable age group with a high prevalence of insomnia and a heightened susceptibility to experiencing psychotic experiences, which in turn increases the risk of developing psychotic disorders. In particular, insomnia symptoms were found to be predominant among noise-sensitive adolescents exhibiting a higher level of noise annoyance. This study aimed to assess the moderating effect of insomnia severity between noise annoyance and psychotic disorders among Lebanese adolescents. A cross-sectional study was conducted among 527 Lebanese adolescents. Participants filled a self-administered online questionnaire. Insomnia moderated the association between noise annoyance and psychotic disorders. Noise annoyance was significantly associated with a higher risk of emergence of psychotic disorders. At low and moderate levels of insomnia severity, higher noise annoyance was significantly associated with higher psychotic experiences. Understanding how these variables interact provide valuable insights into the underlying mechanisms leading to psychotic disorders among adolescents. [ABSTRACT FROM AUTHOR]

This study was conducted to assess noise annoyance following the installation of various types of sound barriers on elevated roads and to forecast the noise reduction effect. The level of annoyance was evaluated using a five-level linguistic rating scale, and noise values were anticipated for each floor of the building using Cadna/A software based on different road service levels. The results showed that for each service level road, the sound barrier’s noise reduction impact was most pronounced at heights of 3.5–5m, and the ratio of the acoustic barrier’s length extension to its distance from the building should not be greater than 4:1. After comparison, it was found that the fully enclosed sound barrier has the best noise reduction effect. Additionally, the noise annoyance level varied significantly at different service levels, with 60.5dB chosen as the noise threshold value. This study could offer an optional path for noise reduction facility design. [ABSTRACT FROM AUTHOR]

The present study analyzed the effect of noise annoyance due to road traffic based on a comprehensive socio-acoustics survey at a large number of sites in the NCT of Delhi. This study presents the development of exposure–effect relationships and noise annoyance models using the Structural Equation Modeling (SEM) approach. The study assesses the traffic noise annoyance caused by road traffic at various sites in NCT of Delhi, India. Exposure–effect relationships correlate the noise annoyance and traffic noise levels. The Structural Equation Model depicts the relationship between noise annoyance and various psychological factors. The effect of noise annoyance and awareness level was determined using a socio-acoustic questionnaire survey among the community of NCT of Delhi. The various parameters undertaken were demographic, honking, health impacts, and psychological perception. The developed PLS (Partial Least Square)–SEM model predicted that noise sensitivity and road traffic noise remarkably affected the noise-induced annoyance.

Abstract The relationship between noise annoyance and risk of cardiovascular disease (CVD) still needs to be fully elucidated. Thus, we examined the relationship between noise annoyance and CVD risk in a large population-based cohort study. Cross-sectional (N = 15,010, aged 35–74 years, baseline investigation period 2007–2012) and prospective data (5- and 10-year follow-up from 2012 to 2022) from the Gutenberg Health Study were used to examine the relationship between noise annoyance due to different sources and risk of prevalent and incident CVD comprising atrial fibrillation, coronary artery disease, myocardial infarction, stroke, chronic heart failure, peripheral artery disease, and venous thromboembolism. In cross-sectional analyses, noise annoyance was an independent risk factor for prevalent CVD, with the strongest associations seen for noise annoyance during sleep (e.g., neighborhood noise annoyance: odds ratio 1.20, 95% confidence interval 1.13–1.27, p

Objectives: This study aimed to explore the impact of irritating sounds on the postural control of healthy adults, considering both linear and nonlinear parameters, subjective assessments, and gender differences. Methods: Thirty-four young participants (17 females, 17 males) completed three 30 s bipedal standing stability tests on a balance platform: one with visual control (EO), another without visual control (EC), and a third without visual control but accompanied by irritating sounds (ECS). Additionally, participants filled out a questionnaire evaluating their sound sensitivity. Linear and nonlinear parameters from each balance test were considered for statistical analysis. Results: The findings reveal significant gender-based variations in sensitivity to sound, with women exhibiting higher sensitivity. No statistically significant differences in postural control were observed between males and females, except for a notable increase in irregularity (SampEn values) in the anterior–posterior direction for females in the ECS trial. Correlation analyses revealed a moderate and statistically significant correlation between SampEn values in the AP direction and SE scores. Conclusions: This study highlights the intricate relationship between sensory stimuli, attention, and the body's ability to maintain balance. The presence of irritating sounds led to increased irregularity in postural control, particularly in the absence of visual control. [ABSTRACT FROM AUTHOR]

Exposure to the excessive noise can leads to serious physiological and psychological effects on human health. The present study was aimed to determine the employees' exposure to noise, and its relationship with their noise annoyance, general health, and aggression. This cross-sectional study was carried out among 113 employees of hospitals in Kurdistan-Iran. The noise pressure level (Leq), noise annoyance, general health, and aggression were evaluated using their own specific tools. Data analyzed using SPSS-V.21 by applying the independent t-test, ANOVA, and Pearson's test, which a significance level of 0.05 was considered. Mean of the Leq in both hospitals was 62.7 ± 4.3 dB. About 42.5% of the staff reported very high noise annoyance. There was a significant relationship between the Leq and noise annoyance (P-value = 0.01). In term of general health, about 44.2% of the staff were healthful, and 35.4%, 17.7%, and 2.7% of them had mild, moderate, and severe symptoms, respectively. Aggression subscales from the highest to the lowest order were related to the verbal aggression, anger, hostility, and physical aggression. The aggression had a significant correlation with the Leq and general health status (P-value < 0.05). The Leq, noise annoyance, general health, and aggression had difference between departments of hospital, but none of these factors were different between work shifts. The emergency, laboratory, and pediatric departments had the highest Leq and the most unfavorable general health. The noise annoyance and aggression in the emergency ward was significantly higher than others (e.g., operating room and CCU). [ABSTRACT FROM AUTHOR]

The relationship between noise annoyance and risk of cardiovascular disease (CVD) still needs to be fully elucidated. Thus, we examined the relationship between noise annoyance and CVD risk in a large population-based cohort study. Cross-sectional (N = 15,010, aged 35–74 years, baseline investigation period 2007–2012) and prospective data (5- and 10-year follow-up from 2012 to 2022) from the Gutenberg Health Study were used to examine the relationship between noise annoyance due to different sources and risk of prevalent and incident CVD comprising atrial fibrillation, coronary artery disease, myocardial infarction, stroke, chronic heart failure, peripheral artery disease, and venous thromboembolism. In cross-sectional analyses, noise annoyance was an independent risk factor for prevalent CVD, with the strongest associations seen for noise annoyance during sleep (e.g., neighborhood noise annoyance: odds ratio 1.20, 95% confidence interval 1.13–1.27, p < 0.0001). While in the 10-year follow-up, mostly positive associations (although not significant) between noise annoyance and incident CVD were observed, no indication of increased CVD risk was observed after 5 years of follow-up. Noise annoyance due to different sources was associated with prevalent CVD, whereas only weak associations with incident CVD were found. Further large-scale studies are needed to establish the relationship between noise annoyance and risk of CVD. [ABSTRACT FROM AUTHOR]

Noise pollution can cause annoyance, significantly threatening the population's health and well-being. This study aimed to find an association between road traffic noise exposure and cardiovascular disease (CVD) risk among residents in Kota Bharu, Malaysia. This descriptive study used a case series approach and surveyed 34 residents in selected residential areas near main roads. An adapted questionnaire was distributed to residents using a purposive sampling method. Questions related to sociodemographic information, self-reporting about CVD, and road traffic noise assessment were asked to investigate the underlying risk factors for CVD. The average score of CVD assessment was classified as moderate risk. No significant association between noise annoyance and CVD was found using multiple linear regression. However, the association between cardiovascular risk and sociodemographic variables, particularly the length of residency at the current address, was statistically significant. Although noise annoyance was not associated with CVD, the length of residency could mediate CVD risk as those living longer in residence might be less vulnerable to the noise. Future longitudinal studies are recommended, which include a noise exposure assessment with a larger sample. [ABSTRACT FROM AUTHOR]

Abstract Background The Weinstein Noise Sensitivity Scale (NSS) is widely recognized as a prominent unidimensional self-reported questionnaire to measure noise sensitivity, which is regarded as the foremost subjective factor moderating the impact of noise on perceived levels of annoyance. In this current study, we conducted an examination of the psychometric properties of a newly translated Arabic version of the short form of the scale (NSS-SF). Methods A sample of 527 Lebanese adolescents participated in the study, completing the NSS-SF with measures of noise annoyance and insomnia. The total sample was randomly divided into two subsamples. Exploratory-to-Confirmatory Factor Analysis (EFA-CFA) was conducted. The normed model chi-square (χ²/df), the Steiger-Lind root mean square error of approximation (RMSEA), the Tucker-Lewis Index (TLI) and the comparative fit index (CFI). Values ≤ 5 for χ²/df, and ≤ 0.08 for RMSEA, and 0.90 for CFI and TLI indicate good fit of the model to the data. Composite reliability in both subsamples was assessed using McDonald’s ω and Cronbach’s alpha. Results EFA results on the first split-half subsample revealed that one item (item 2) was removed because of low communality (

A participatory-based intervention was performed in Sweden, aimed at improving the sound environment in one preschool (n = 20) and one obstetric ward (n = 50), with two controls each (n = 28, n = 66). Measured sound levels, and surveys of noise annoyance, hearing-related symptoms and emotional exhaustion were collected before, and three and nine months after the interventions, comparing intervention and control groups over time. The results of this first implementation in a limited number of workplaces showed significantly worsening of hyperacusis, sound-induced auditory fatigue, emotional exhaustion and increased sound levels in the preschool, and worsening of noise annoyance in both intervention groups. Increased risk awareness, limited implementation support and lack of psychosocial interventions may explain the worsening in outcomes, as might the worse baseline in the intervention groups. The complexity of the demands in human-service workplaces calls for further intervention studies. [ABSTRACT FROM AUTHOR]

Composite reliability in both subsamples was assessed using McDonald's ω and Cronbach's alpha. Results: EFA results on the first split-half subsample revealed that one item (item 2) was removed because of low communality (< 0.3); the other 4 items converged on one factor, which explained 67.85% of the common variance (ω = 0.84 and α = 0.84). CFA was conducted on the second half-split subsample in adults according to the model obtained on the first split-half subsample; the fit indices were acceptable as follows: χ2/df = 5.07/2 = 2.54, p <.001, RMSEA = 0.076 (90% CI 0.001, 0.160), SRMR = 0.021, CFI = 0.992, and TLI = 0.976 (ω = 0.84 and α = 0.84). Configural, metric, and scalar invariance was supported across gender in the total sample. Conclusion: Our findings substantiate that the Arabic version of the NSS-SF is a reliable, psychometrically valid instrument for assessing noise sensitivity among Arab adolescents, thereby enhancing its overall utility and applicability within Arab countries.

Introduction: Traffic noise annoyance is one of the consequences of urban life which can have adverse effects on human health including sleep quality. The present study intends to investigate the extent of noise annoyance and its relationship with sleep quality of residents adjacent to high- and low-traffic roads in Yazd city in 2019. Methods: This was a cross-sectional study conducted in 2019 in Yazd. Data were collected using two standard questionnaires of assessing noise annoyance and Pittsburgh sleep quality. Responses were collected from residents around 10 high- and low-traffic roads, and a total of 200 samples were obtained randomly. Results: The mean score of sleep quality for all participants was 11.5 ± 35.25, and the mean score of noise annoyance was 3.73± 1.9. There was a significant difference between the average quality of sleep and the score of noise annoyance in terms the type of road (P/00.001). In general, there was also a significant and direct correlation between noise annoyance and sleep quality (r = 0.569, P = 0.001). But, the correlation between these two variables was not significant with the separation of the types of roads. Conclusion: Based on the results of the present study, the quality of sleep of residents around high traffic roads is moderate, which suggests that noise annoyance caused by traffic affects the quality of sleep. In other words, the noise annoyance caused by traffic has reduced the quality of sleep in people living adjacent to high-traffic roads. [ABSTRACT FROM AUTHOR]

Outdoor environmental noise is a major source of annoyance in urban areas and exposure to it can increase the risk of severe health issues. Consequently, it has been the focus of research for decades. Even though people spend the majority of their time indoors, most studies use outdoor noise levels and do not include indoor noise measurements to estimate real exposure levels. This study conducted simultaneous indoor and outdoor noise measurements for 24 h in four multi-unit residential buildings to identify the levels and sources of outdoor noise heard indoors and quantify the effects of outdoor noise on indoor levels. The measurements were conducted in unoccupied suites that are most exposed to traffic and other outdoor noise sources. Surveys were administered following building occupancy to collect information regarding perceived acoustic comfort levels due to outdoor noise. The indoor LAeq,24h in three of the study buildings were above 40 dB(A) and exceeded WHO's noise level limits. Regression analysis showed that outdoor noise only explains 14%–58% of the variability in indoor noise levels. This is mainly because of heating, ventilation, and air conditioning (HVAC) system noise which resulted in consistently high indoor noise levels despite variations in outdoor noise. Analysis of the survey showed a poor correlation between reported annoyance and measured noise levels. But annoyance strongly depended on other factors such as suite location and noise sensitivity. The findings show that outdoor noise measurements alone may not be good predictors of exposure levels and the effects of outdoor noise on occupants. [ABSTRACT FROM AUTHOR]

Several policies have been developed to improve the quality of life for older adults in cities, with soundscape being one of the factors that most influence general comfort. This work aims to present a systematic review based on PRISMA methodology, of the existing scientific literature that identifies the differences in sensitivity, noise annoyance, acoustic comfort, and urban soundscape preference of the elders with the rest of the population. Soundscape evaluation is a complex issue, understood as the relationship between human beings and the acoustic environment, based on sound, environment, and people's perceptions of those. Among the personal variables, age is related to physiological, psychological, social, and cultural factors that lead to evaluate urban soundscape in a certain way. Our results show that the greatest difference among older adults and other age groups is presented on noise annoyance and the least differences were presented on sound level evaluation. More research is needed in this field, to achieve comfortable urban areas through soundscape design which should be pleasant and inclusive for all, including elders as a vulnerable group, and contribute to improving their health and quality of life.

Noise mapping is based on long-term noise indicators, such as L N or L DEN. On the other hand, transportation intensity changes during a day (road traffic peak hours) or a year (more flights during holidays) and this variability is not reflected in single sound level values. We wanted to find out whether not only sound level but also the number of noise events is the factor influencing noise annoyance assessment. Ambisonic recordings of real traffic in a city were used. Road, tramway, and aircraft traffic were investigated and two factors were manipulated: the equivalent sound level value and the number of noise events. All stimuli were presented in an anechoic chamber. The results showed that sound level is always a statistically significant parameter while the number of events has an impact only for tramways and airplanes. Moreover, the difference is observed only between one or more subgroups, no matter what the sound level value was. For road traffic this relation was not found to be statistically significant. It was also shown that the existence of tramway bonus or airplane malus is linked with the number of noise events.

The paper deals with the process of environmental risk assessment from exposure to noise from tram traffic. As part of the monitoring of the acoustic situation, measurements of sound pressure levels A were made and evaluated. The survey confirmed the existence of an acoustic risk in the form of a disturbing wailing sound when a tram vehicle passes through a directional curve with a radius of less than 50m. In addition to causing annoyance, the tonal variation of sound above 65 dB causes frostiness, cardiovascular, psychological and auditory problems, thereby damaging the health of people living and moving around the transport routes.

Annoyance and sleep disturbance are the most common community responses to road traffic noise, and they account for the majority of the environmental noise burden in Europe. The findings of a cross-sectional study - a questionnaire survey of residents living in newly built apartment houses in some Slovak towns (Bratislava, Trencin, Martin, Piestany) are presented in this paper. The average age of the 543 respondents was 45 ± 4 years, 53 % were females, and 81 % had lived in their current home for more than five years. Traffic noise measurements on noisy facades LAeq,day = 51.8 dB to 72.4 dB, LAeq,night = 41.9 dB to 64 dB were supplemented by a standardized questionnaire. In comparison to respondents with bedroom windows facing quiet streets, those who face noisy streets are less satisfied with their quality of life, less sensitive to noise, and more irritable and restless during the day and night OR = 2.54; 95 % CI = 1.38-4.92. After the results have become completed, we hope to suggest temporary solutions for noisy apartment building facades, as well as intervention techniques, and to apply sound city planning principles.

Introduction: One of the most important sources of pollution is the noise generated by traffic and transportation, especially the urban railway system (metro), thus this study aimed to assess the noise exposure of Tehran Metro employees and its relation with noise annoyance and audiometric results of employees. Materials and methods: Measurement was done by using a TES-1351B sound level meter recommendations for all employees which consists of the staff of the station affairs and the staff of the administrative department. A self-reporting questionnaire on workplace noise annoyance were distributed to the employees and then audiometric were used to measure the employees' hearing level. Results: The average noise exposure in platform workers was 79.3±10 dB and in control room workers was 56.5±6.9 dB. A significant difference was found between the average noise exposure in the employees of the two groups (control room-platform) (p-value=0.001). Based on the results, noise in the work environment was significantly more annoying for people working in metro line 1 than in line 6 (p-value=0.025). Conclusion: These results show that in general, due to the sound pressure level of 10% of the platform employees being higher than the permissible limit and the increase in the level of noise annoyance of the employees at the frequency of 8 kHz, it is necessary to plan and adopt administrative and technical-engineering measures to reduce the level of noise pollution to about it seems necessary to allow the standard.

Although wind power is more acceptable in terms of its environmental impact, possible risks to human health are still being discussed. The aim of this study is to systematically evaluate the methodology and the outcomes of the articles that investigate the health effects of wind turbines on humans. Combinations of keywords were entered into the PubMed database. The search resulted in a total of 141 hits, 22 were included. It had been noticed that the most common problems in those living around the wind turbines are noise annoyance(n=18), risk perception and attitude towards wind turbines(n=11), general health symptoms and quality of life(n=11), sleep disturbance(n=10), annoyance(n=7) and shadow flicker effect(n=4). General annoyance is adversely affected by the noise level and sensitivity to noise. We can conclude that the knowledge of and attitude towards wind turbines can turn into annoyance and symptoms if the audio-visual effects of turbines limit daily life activities.

The long‐term effect of noise pollution is a serious environmental concern for those living near the road due to numerous anthropogenic activities. A calibrated sound level meter was used to assess the noise levels in a semi‐urban area known as Basudevpur Town (16 squares) in March 2021. A sample of the general public (126) was taken and interviewed using a questionnaire to find out how they felt about noise pollution and its impact on their health. A relationship between demographic characteristics and public health issues was discovered in the current investigation. The ANNOVA test was used to determine the association between noise exposure and the probable impacts of this noise exposure on this town, and the Chi‐square test in SPSS 20.0 was utilized to study the relationships between demographic character and irritation. The study reveals that the noise levels were greater than the CPCB's permissible limit for Indian road conditions. The primary source of noise, according to the study, is road traffic noise. The impact of noise pollution on the public's sleep problem was also analyzed. In order to limit noise pollution and its influence on public health, proper administrative planning is necessary.

Metro operations inevitably generate noise inside trains. For better understanding the characteristics of interior noise, we conducted interior noise measurements on 12 subway lines in a Chinese city, objectively explored the reasons for psychological annoyance. By conducting a survey on passengers, we investigated the noise-components that cause an increase in subjective annoyance and used ordinal logistic regression to explore the key factors. Finally, the noise time–frequency characteristics under different operating conditions were discussed. The results showed that loudness is the primary factor causing psychological annoyance. Rail corrugation, especially in the 63–125 Hz range, and broadcasts are the main noise sources that cause annoyance. There was a strong correlation between subjective annoyance and noise sensitivity, and track spatial position and alignment, while vehicle type and seating position had no significant effect. A new index has been proposed for quantifying subjective annoyance. During maintenance, attention should be paid to rail corrugation. [ABSTRACT FROM AUTHOR]

Objective: This study explored the interaction between environment and behavior and analyzed the effect of physical environment stimuli and individual differences on environmental perception. Methods: We investigated the effects of two kinds of noise sensitivities (high sensitivity and low sensitivity) and three kinds of noise types (quiet, road traffic noise, and speech noise) on working memory and noise annoyance of college students through questionnaires and experiments. Results: (i) noise sensitivity was positively correlated with neuroticism and negatively correlated with conscientiousness. (ii) The interaction between noise sensitivity and noise type significantly affected the accuracy of working memory. (iii) Both noise sensitivity and the main effect of noise type significantly affected the response time of working memory. (iv) The interaction between noise sensitivity and noise type significantly affects noise annoyance. Conclusion: There were significant differences in working memory performance and subjective noise annoyance among individuals with different levels of noise sensitivity.

Transport noise is a serious problem in cities and has a negative impact on both health and economics. In addition to the aforementioned unnoticed health effects, traffic noise has also been identified as one of the leading causes of sleep disorders, annoyance and negative cardiovascular effects. This research consists of three parts: part one involves onsite measurements of traffic noise in Trakai town; part two simulates traffic noise at different average vehicle speeds; part three assesses the number of people affected by traffic noise. The carried-out simulation has demonstrated that the noise level changes very slightly at different average vehicle speeds. It should be noticed that more noise is generated at average vehicle speed of 30 km/h rather than at 50 km/h. The assessment of the annoyance level has disclosed that an average vehicle speed of 30 km/h should cause the highest level of annoyance (highest – 26.8%).

The significant growth in traffic density in Slovakia, combined with the country’s economic change, has resulted in new environmental noise issues, particularly in road traffic noise. The objective of this study was to assess and evaluate the impact of environmental noise on the psychosocial well-being of young healthy individuals in the two main Slovak cities of Bratislava and Kosice. To assess noise annoyance, interference with activities, and sleep disturbance, the ICBEN (The International Commission on the Biological Effects of Noise) anonymous validated “Noise annoyance questionnaire” was applied; noise levels were objectified by direct measurements using a sound level analyzer with a frequency analysis module. Young individuals between the ages of 20 and 30 were interviewed in Bratislava (533 respondents, 155 males) and Kosice (355 respondents, 111 males). The majority of the respondents in both cities were exposed to medium levels of road traffic noise LAeq≥ 60 dB. In Bratislava, 27.82 % of respondents resided in the higher noise exposure category LAeq≥ 70 dB, while in Kosice, 39.9 % resided in the lower noise exposure category LAeq< 50 dB. Road traffic noise annoys respondents in the higher noise exposure category in Bratislava 63.51 %, and even in the lower noise exposure category in Kosice, it interferes with reading and mental work, sleep and falling asleep 46.51 %. The study has identified traffic noise as an environmental issue in large cities, emphasizing the need for vulnerable individuals to be protected, particularly at night.

BackgroundWhile chronic exposure to high levels of noise was demonstrated to increase the risk of various cardiovascular diseases, the association between noise annoyance and risk of cardiovascular disease remains still inconsistent. Recently, we showed that noise annoyance is associated with prevalent atrial fibrillation in the general population. However, the association between noise annoyance and risk of incident atrial fibrillation as well as potential sex-differences remain still elusive.Methods and results15,010 subjects from a German population-based cohort were examined at baseline (2007 to 2012) and follow-up five years later (2012 to 2017) to investigative the association between noise annoyance due to multiple sources and prevalent and incident atrial fibrillation. After multivariable adjustment, the results from logistic regression analyses revealed overall consistent and positive associations between noise annoyance and prevalent and incident atrial fibrillation in men, whereas this association was weaker in women, in particular with respect to incident atrial fibrillation. For instance, industrial noise annoyance was associated with 21% (95% confidence interval (CI) 9–34%) and 18% (8–29%) higher odds of prevalent atrial fibrillation in men and women, respectively. In prospective analysis, this association remained stable in men (odds ratio (OR) 1.25, 1.07–1.44), while in women no association was observed (OR 1.03, 0.89–1.18).ConclusionsThe findings suggest that noise annoyance can increase the risk of incident atrial fibrillation in a large population-based cohort and that men may be more sensitive to the adverse effects of noise annoyance with regard to the risk of atrial fibrillation.

Industrial noise sources are among the environmental noise sources that are ranked second among the causes of ill health in Europe by the World Health Organization. The aim of this paper is to summarize and review of published information focusing on noise annoyance from industrial activities and mining. A search for articles was performed using the bibliographic databases platforms. The epidemiological evidence shows that environmental noise may be associated with cardiovascular and metabolic diseases, impaired cognitive development in children, mental health, post-irritability, and sleep disturbances. As a result of efforts to minimize the effects of industrial noise on human health, the New South Wales Environment Protection Authority published A Guide to the Noise Policy for Industry in 2017, which sets out recommended noise levels, methods, and procedures for noise management based on the latest scientific evidence. Social networks can be used to assess the population's noise annoyance and to verify the effectiveness of the measures. The industrial noise sources are typically defined by low-frequency noise. Low-frequency noise has very low attenuation and is only slightly affected by obstacles, therefore it can be a major cause of night noise annoyance. An association was confirmed between exposure to low-frequency noise and sleep disturbance, psychological problems, cognitive impairment, increased social conflicts, anxiety, emotional instability, nervousness, and reduced mental performance - concentration, and visual perception. In view of the long tradition of mining and industry, the assessment of noise from these activities from the perspective of its impacts on human health is an inherent part of legislative processes.

Abstract Background Poor acoustic conditions at home can have negative health impact. The aim was to investigate home environment factors and medical symptoms associated with noise disturbance. Methods All adults (≥18 y) registered in selected apartments in Sweden were invited to participate in a questionnaire survey including medical questions and personal factors. Totally 5775 adults participated (response rate 46%). Information on home environment was obtained through an indoor environment questionnaire. Two-level logistic regression models (individual, municipality) were performed to estimate associations. Results Totally 11.9% reported noise disturbance in general at home. Noise disturbance from voice/radio/TV/music/similar sounds from neighbours (13.2%), scraping sound/footsteps/thumping from neighbours (16.5%) and road traffic (16.1%) were common. Younger age and smoking were related to more noise disturbance and more medical symptoms. Noise disturbance was related to tiredness, headache and difficulty concentrating (OR = 1.70–8.19). Renting the apartment (OR = 2.53) and living above ground floor (OR = 1.37) were related to more noise disturbance in general. Living in newer buildings (constructed from 1986 to 2005) was related to less noise disturbance in general (OR = 0.40–0.59). A warmer climate (OR = 1.95), higher municipality population density (OR = 1.24), a longer living time (OR = 1.34), construction year (1961–1975) (OR = 2.42), renting (OR = 1.80–2.32), living above ground floor (OR = 1.45) and having a bathroom fan (OR = 1.84) were associated with increased noise disturbance from neighbours. Factors associated with increased noise disturbance from installations or ventilation/fans/heat pumps included a warmer climate, higher municipality population density, construction year (1961–1995), renting and any mechanical ventilation. Higher municipality population density, construction year (especially 1961–1985) and renting were associated with more noise disturbance from traffic (OR = 1.77–3.92). Renting the apartment (OR = 1.73) and living above ground floor (OR = 1.60) were related to more severe traffic noise disturbances. Noise disturbance in general was partly a mediator of the effects of old buildings, renting the apartment and lack of mechanical ventilation on medical symptoms (% of total effect mediated by noise disturbance: 19–44.8%). Conclusions Noise disturbance can be associated medical symptoms. Younger age, smoking, a warmer climate, higher municipality population density and different building factors (e.g. renting the apartment, construction period 1961–1985) can be associated with noise disturbance.

Few studies have focused on the simultaneous effects of air pollution and noise annoyance on human mental health. Using a panel study design, we studied the concurrent effect of short-term exposure to PM2.5 and noise annoyance on mental health outcomes by recruiting a sample of 110 students from Tehran University of Medical Sciences. Mental health was evaluated in terms of depression, anxiety, and stress symptoms using validated, standardized DASS-21 questionnaires in three time periods. Average daily exposures over a 6-day period were assigned to participants based on the closest stationary monitor during hours spent on campus and in the dormitory. The noise annoyance was evaluated based on self-reported scale. We used random intercept mixed-effect model, adjusting for potential confounders. An increase in PM2.5 and noise annoyance was significantly associated with mental health outcomes in crude and adjusted analysis. For example, an IQR increase in PM2.5 was associated with a 2.57 point (95% CI: 1.40, 3.74) increase in depression score, 2.11 point (95% CI: 0.94, 3.28) increase in anxiety score, and 1.64 point (95% CI: 0.47, 3.04) increase in stress score. PM2.5 in crude analysis was also positively associated with all three-outcome adjusting for economic status, sex, and noise annoyance. Overall, our findings revealed evidence confirming an association between short-term exposure to environmental PM2.5 and noise annoyance increased outcomes of depression, stress, and anxiety.

Objective: This study explored the interaction between environment and behavior and analyzed the effect of physical environment stimuli and individual differences on environmental perception.Methods: We investigated the effects of two kinds of noise sensitivities (high sensitivity and low sensitivity) and three kinds of noise types (quiet, road traffic noise, and speech noise) on working memory and noise annoyance of college students through questionnaires and experiments.Results: (i) noise sensitivity was positively correlated with neuroticism and negatively correlated with conscientiousness. (ii) The interaction between noise sensitivity and noise type significantly affected the accuracy of working memory. (iii) Both noise sensitivity and the main effect of noise type significantly affected the response time of working memory. (iv) The interaction between noise sensitivity and noise type significantly affects noise annoyance.Conclusion: There were significant differences in working memory performance and subjective noise annoyance among individuals with different levels of noise sensitivity.

Purpose: The aim of this study was to investigate the association between the psychological distress and sleep problems with environmental noise annoyance in adult population. Methods: This is a cross-sectional study on 822 adult population of Tehran City in 2016. Integrated cluster stratified random sampling and Kish grid method were used. Noise annoyance, the day-night average sound level (Ldn), nighttime average sound level (Lnight), and daytime average sound level (Lday) were selected as noise exposure indicators. The prevalence of psychological distress and sleep problems were assessed using the Kessler Psychological Distress Scale (K10) and the PSQI questionnaire, respectively. Multiple logistic regression analysis was applied for data analysis. Results: Among the participants 46.03%% were exposed to a sound level higher than the daytime standard level (55 dB) and 84.6% were exposed to a level higher than the nighttime standard limit (45 dBA). According to the results, 49% of the subjects had poor sleep quality and 66% were highly sensitive to noise. In addition, 17.73% had a high risk of mental disorders and 16.48% were found to have a mild risk of mental disorders. There was found a statistically significant association between psychological distress and the noise annoyance at home (OR = 1.3 CI 95% (1.17–1.44)) and at work environment (OR = 1.18 CI 95% (1.08–1.28)). Conclusion: The findings indicated that the study population was highly sensitive to noise. In addition, the relatively high percentage of people who exposed to non-standard levels of sound indicates that this exposure has the potential to cause physical and mental consequences among them.

Classrooms are noisy, yet little is known about pupils' subjective reactions to noise. We surveyed 112 children between 8.70 and 11.38 years of age and extracted five dimensions in their reactions to noise by factorial analyses: (1) perceived classroom loudness, (2) hearing difficulties, (3) attention capture, (4) interference, (5) annoyance from noise. Structural Equation Models were run to better understand interindividual differences in noise interference and annoyance. Children reporting hearing and switching difficulties experienced more interference and annoyance from noise. Children who had a greater propensity for mind-wandering also experienced more interference from noise, but were annoyed by noise only to the extent that it produced interference--the relationship between mind-wandering and noise annoyance was indirect, and not direct, as was the case for reported hearing and switching difficulties. We suggest that the distinction between annoyance and interference has theoretical, empirical, and practical relevance for educational research. [ABSTRACT FROM AUTHOR]

Transport noise is a serious problem in cities and has a negative impact on both health and economics. In addition to the aforementioned unnoticed health effects, traffic noise has also been identified as one of the leading causes of sleep disorders, annoyance and negative cardiovascular effects. This research consists of three parts: part one involves onsite measurements of traffic noise in Trakai town; part two simulates traffic noise at different average vehicle speeds; part three assesses the number of people affected by traffic noise. The carried-out simulation has demonstrated that the noise level changes very slightly at different average vehicle speeds. It should be noticed that more noise is generated at average vehicle speed of 30 km/h rather than at 50 km/h. The assessment of the annoyance level has disclosed that an average vehicle speed of 30 km/h should cause the highest level of annoyance (highest - 26.8%). [ABSTRACT FROM AUTHOR]

Introduction: Although noise characteristics such as intensity and frequency are the main cause of detrimental effects, it is important to pay attention to the personality traits of individuals as the host of adverse health effects. The aim of this study was to investigate the effect of personality traits on sensitivity, annoyance and loudness perception due to exposure to high frequency sound. Material and method: This interventional and experimental study was carried out among 80 undergraduate and postgraduate students in 2017. First, examinee were exposed to a high frequency noise at 65 dBA for one hour in an acoustic room. Then, to determine amount of annoyance, sensitivity, loudness perception and to investigate personality traits, questionnaire of noise annoyance, noise sensitivity, loudness perception and Eysenck personality inventory was used, respectively. Finally, Chi-square, independent t-test and multivariate analysis of variance (MANOVA) were used to data analyze. Results: The mean±SD of sensitivity, annoyance and loudness perception were 54.08±7.71, 7.0±1.53, and 2.79±1.13, respectively in this study. The mean scores of sensitivity, annoyance and loudness perception were significantly different in terms of personality traits, so that their average was higher in the neurotic and introverted. Based on MANOVA test results, personality traits had a significant effect on sensitivity, annoyance and loudness perception of individuals. In a way, the neuroticism and introversion had the greatest effect on the sensitivity and annoyance, respectively. Conclusion: The results of this study showed that personality traits such as introversion and neuroticism can affect the sensitivity, annoyance and loudness perception of individuals.

This systematic review investigates the certainty of evidence (CoE) regarding noise annoyance as a determinant of biological changes known to contribute to disease development. We searched PubMed MEDLINE, EMBASE, Cochrane Central, and CINAHL for English-language comparative studies conducted on humans of any age from 1 January 1940, to 28 August 2023. Further, studies that provided quantitative data on the relationship between noise annoyance and biomarkers of interest were included. Where possible, random-effects meta-analyses were used to calculate the odds ratios of noise annoyance on biomarkers and biological conditions considered to be risk factors for developing health effects. The risk of bias of individual studies was assessed using the Risk of Bias of Non-randomized Studies of Exposures (ROBINS-E) instrument. The CoE for each outcome was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. The search identified 23 primary studies reporting on relevant biomarkers. Although some studies and pooled estimates suggest a possible association between noise annoyance and biological measures, the CoE overall is very low due to concerns with the risk of bias, inconsistency, and imprecision in the estimates of effects. In the context of environmental impact assessment, where guidelines aim to mitigate the prevalence of populations experiencing a high level of noise annoyance, our results suggest that such practices should be grounded in the understanding that annoyance is health-relevant because it reflects an undesirable reaction to noise, rather than a precursor to chronic physical health conditions.

Background: Poor acoustic conditions at home can have negative health impact. The aim was to investigate home environment factors and medical symptoms associated with noise disturbance.Methods: All adults (≥18 y) registered in selected apartments in Sweden were invited to participate in a questionnaire survey including medical questions and personal factors. Totally 5775 adults participated (response rate 46%). Information on home environment was obtained through an indoor environment questionnaire. Two-level logistic regression models (individual, municipality) were performed to estimate associations.Results: Totally 11.9% reported noise disturbance in general at home. Noise disturbance from voice/radio/TV/music/similar sounds from neighbours (13.2%), scraping sound/footsteps/thumping from neighbours (16.5%) and road traffic (16.1%) were common. Younger age and smoking were related to more noise disturbance and more medical symptoms. Noise disturbance was related to tiredness, headache and difficulty concentrating (OR = 1.70-8.19). Renting the apartment (OR = 2.53) and living above ground floor (OR = 1.37) were related to more noise disturbance in general. Living in newer buildings (constructed from 1986 to 2005) was related to less noise disturbance in general (OR = 0.40-0.59). A warmer climate (OR = 1.95), higher municipality population density (OR = 1.24), a longer living time (OR = 1.34), construction year (1961-1975) (OR = 2.42), renting (OR = 1.80-2.32), living above ground floor (OR = 1.45) and having a bathroom fan (OR = 1.84) were associated with increased noise disturbance from neighbours. Factors associated with increased noise disturbance from installations or ventilation/fans/heat pumps included a warmer climate, higher municipality population density, construction year (1961-1995), renting and any mechanical ventilation. Higher municipality population density, construction year (especially 1961-1985) and renting were associated with more noise disturbance from traffic (OR = 1.77-3.92). Renting the apartment (OR = 1.73) and living above ground floor (OR = 1.60) were related to more severe traffic noise disturbances. Noise disturbance in general was partly a mediator of the effects of old buildings, renting the apartment and lack of mechanical ventilation on medical symptoms (% of total effect mediated by noise disturbance: 19-44.8%).Conclusions: Noise disturbance can be associated medical symptoms. Younger age, smoking, a warmer climate, higher municipality population density and different building factors (e.g. renting the apartment, construction period 1961-1985) can be associated with noise disturbance.

Introduction: The body's response to noise pollution is very similar to the way the body responds to stress, which can lead to poor health over time. In this regard, this study was conducted to determine the general health of the elderly and its relationship with traffic noise pollution in Ardakan. Methods: This descriptive cross-sectional study was conducted in 1399. Participants were 200 elderly people in Ardakan chosen by random sampling. Data were collected through sound measurement with SVANTEK device, General Health Questionnaire 28 (GHQ-28). After completing the questionnaires and measurements, the collected data were entered into SPSS-19 software and descriptive statistics as well as analytical statistics such as Chi-square, regression and analysis of variance were used to analyze them. Results: The overall average sound level equivalent in decibels at all measuring stations was within the standard range. There was a significant relationship between noise annoyance, the dimensions of "anxiety symptoms,sleep disorders",and "depressive symptoms" of general health (p <0.001). Conclusion: People with more noise annoyance experience more anxiety, sleep disorders and depression. Existence of noise pollution levels in the allowable or standard level can lead to the observation of no significant relationship between traffic noise pollution levels and general health. Reducing anxiety, depression and sleep disorders in the elderly is possible with interventions to reduce noise annoyance in them. [ABSTRACT FROM AUTHOR]

Noisiness in the working environment was largely proved to have effects on the working activity and performance. To limit the spreading of the COVID-19 pandemic in the first wave between March and May 2020, Italian workers had massively started performing remote working. Insights on the subjective perception of noise annoyance under the remote working settings were thus necessary. Workers from a university and from several large and small Italian companies, resulting in 1,934 participants overall, answered to a questionnaire on the perception of noise annoyance in the remote working environment. A total of 57% of the responding workers stated to be sensitive to noise. The questionnaire was delivered online; data were recorded anonymously and then aggregated for statistical analyses. Results show that 55% of the workers perform their activity in an isolated room of the home environment, 43% in a shared room (e.g., kitchen, living room), and 2% in an outdoor space, with the majority of workers (57%) performing activity without other people in the environment. Among the noise sources investigated, 25% of workers recognize the noise generated by people (e.g., talking, moving, calling, listening to music) as the main source of disturbance. The negative consequences of noise annoyance during the remote working hours are mainly related to a loss of concentration and to a difficulty in relaxing. Furthermore, workers reported to get easily irritated by noise generated from the neighborhoods or from the housemates as it tends to distract from finishing a task.

This study aims to examine the influence of colour exposure on noise annoyance. Previous studies in the literature have focused mostly on the effects of colour exposure on loudness judgements; however, due to the cognitive nature of multisensory perception, the influence of colour on noise annoyance also needs to be investigated. Our experiments were designed to administer non-information-carrying sound signals (i.e. white noise) and visual stimuli (i.e. abstract colour samples) and to limit visual and auditory contextual information. Participants were asked to evaluate noise annoyance on an 11-point International Commission on Biological Effects of Noise (ICBEN) scale. The experiments were conducted in the form of audio-visual tests. During these tests, random combinations of three white noise sound samples with sound pressure levels of 66 dB(A) (−4 dB[A] acoustic condition), 70 dB(A) (0 dB[A] acoustic condition) and 74 dB(A) (+4 dB[A] acoustic condition), and six visual stimuli, including the elementary colours of the Natural Colour System (NCS)—yellow (Y), red (R), blue (B), green (G), white (W) and black (S)—were presented to a total of 42 participants. The black colour sample was used to measure the audio-only control condition for the three white noise sound samples. The results of the study reveal that the effects of sound, the effects of colour and the interaction effects of colour and sound on perceived noise annoyance were statistically significant. The effects of colour on the loudness evaluations of the previous studies and the effects of colour on noise annoyance evaluations presented in this study show very similar and concordant results, indicating that the effects of colour on noise annoyance depend on the sound pressure level (SPL). The results indicate that the hue contrasts of red–green, red–blue and yellow–blue and the lightness contrast of yellow–blue influenced perceived noise annoyance when the SPL was low or high. Within the contrast pairs, red and yellow were perceived to be annoying, whereas blue and green were perceived to be non-annoying. [ABSTRACT FROM AUTHOR]

• Standardized tram noise measurements in the normal operation conditions. • Psychoacoustic measures calculation and different statistical analyses and verification. • More effective approach to assessment the tram noise annoyance in the cities. Current environmental standards rely on A-weighted equivalent noise levels (L Aeq) or Single Event Level (SEL), which have limitations. This article presents the results of a study on tram noise annoyance in the context of different acoustic measures proposing a different approach to assessing traffic noise in the city. The main objective of the study was to understand how different noise measures may differ in assessing noise annoyance. The study was based on an analysis of 173 tram passages. The results show significant variation in noise ratings based on different measures. It was noted that the highest number of exceedances of the limits (15.0%) was identified by the Annoyance Index model and Articulation Index, while the least was identified by the currently used SEL measure (8.1%). The results suggest that high SEL values are not always directly correlated with the perception of sound as loud or unpleasant. Such an approach can contribute to a better understanding and management of urban noise, which in turn can lead to improved quality of life for residents. [ABSTRACT FROM AUTHOR]
