Objective: Examine the association between military blast exposure and functional status among veterans with a focus on functional disability as a proxy for quality of life and explore the potential modifying effect of hearing loss on this association., Study Design: Prospective cohort., Setting: Multi-institutional tertiary referral centers., Patients: 540 veterans., Exposure: Self-reported military blast exposure with and without tinnitus; high-frequency hearing loss (yes/no)., Main Outcome Measure: WHO Disability Assessment Schedule 2.0 questionnaires at baseline and annually over 5 years. The odds of membership into three functional disability trajectory groups: low functional disability, moderate functional disability, and high functional disability., Results: Of 540 veterans, 197 (36.5%) self-reported a blast exposure history, and 106 of 197 (53.8%) reported tinnitus as a direct result of the blast. Blast exposure without tinnitus increased the odds of moderate functional disability compared with low functional disability (odds ratio [OR] = 1.5; 95% confidence interval [CI], 0.92-2.51), which strengthened among those with blast with tinnitus (OR, 3.6; 95% CI, 2.1-6.1). Blast exposure without tinnitus also increased the odds of membership to high functional disability versus low functional disability (OR, 2.2; 95% CI, 1.1-4.8). Hearing loss further increased the odds of reporting functional disability. The probability of low functional disability was approximately 60% if there was no history of blast or hearing loss, dropping to 20% if there was blast, tinnitus, and hearing loss history., Conclusions: Blast exposure negatively affects the quality of life of veterans, especially when compounded with tinnitus and hearing loss., Competing Interests: The authors disclose no conflicts of interest., (Copyright © 2024, Otology & Neurotology, Inc.)

Purpose: In 2021, the Veterans Health Administration (VHA) and Department of Defense (DOD) Tinnitus Working Group conducted a survey of DOD and VHA clinicians to evaluate clinical services provided for tinnitus., Method: The online survey included a mix of multiple-choice and open-ended questions. Respondents included VHA and DOD health care providers in audiology, otolaryngology, mental health, and primary care, as well as DOD hearing conservation technicians. Quantitative and qualitative methods were used to analyze the data., Results: A total of 669 providers responded to this combined survey. Results indicated that compared to DOD and VHA providers in other fields, audiologists tended to be more confident and more aware of their role in tinnitus management. In terms of confidence and scope of practice, DOD mental health care providers were the group least familiar with tinnitus care. Other results explored herein include barriers to tinnitus care, facilitators for progressive tinnitus management programs, interventions and patient materials offered, new patient materials wanted, and respondents' preferred information sources and training methods., Conclusion: Survey results indicated that more directed education and support are needed to increase DOD and VHA clinicians' awareness of the need for tinnitus services and their roles in providing that care., Supplemental Material: https://doi.org/10.23641/asha.27229215.

Purpose: Tinnitus is a common health condition in the general population, with increased prevalence among military Veterans. Tinnitus is, in fact, the most prevalent military service-connected disability. There is no cure for tinnitus, but interventions are available to help patients manage their reactions to tinnitus and reduce its functional impact. Progressive tinnitus management (PTM) is a stepped-care protocol that involves coordinated audiological and behavioral health clinical services. PTM was endorsed by national Veterans Affairs (VA) audiology leadership in 2009. Given new clinical insights and research findings since the initial rollout of PTM, it remains necessary to improve and update the protocol in response to feedback from clinicians and patients., Method: This two-phase quality improvement project captured quantitative and qualitative feedback from VA and Department of Defense (DOD) clinicians and patients concerning PTM materials. A convergent parallel mixed-methods design was used to integrate the quantitative and qualitative data, and a consensus method was used to adjudicate any discrepant findings., Results: In Phase 1, 21 VAs and DOD clinicians and patients completed semistructured interviews and quantitative measures on the PTM handbook and workbook revisions. Phase 1 findings were recommendations to modify content, format, and adaptations of content (e.g., electronic formats with a clickable index). In Phase 2, six non-Veteran patients assisted in pilot testing PTM PowerPoint slides used by clinicians for PTM skills education sessions. Phase 2 findings indicated that the revised PTM PowerPoint slides were useful and clinically acceptable., Conclusions: Findings from this study are being used to revise and update materials in the PTM skills education sessions. More generally, the study demonstrates the necessity of end-user input to inform and implement clinical updates., Supplemental Material: https://doi.org/10.23641/asha.27057691.

Many studies have attempted to determine methodology for interpreting change on outcome instruments that result from an intervention. The objective of these studies has been to devise methods to identify the minimal level of change that would be consistent with actual benefit perceived by the patient, and not just statistically significant change. With respect to intervention for bothersome tinnitus, the authors of the original study to develop and validate the Tinnitus Functional Index (TFI) suggested that a minimum 13-point reduction in the TFI score was likely to reflect a change perceived as meaningful to an individual. The 13-point estimation of meaningful change for an individual is appropriate for use with any adult seeking care for tinnitus. However, it cannot be relied upon in isolation to determine if an individual believes that there has been a noticeable, or meaningful improvement in their quality of life. It is important to use subjective impressions elicited from the patient to assist in interpreting the meaning of TFI data for an individual. For clinicians engaging in care for tinnitus, we recommend using the TFI and pairing it with the patient's belief/impression as to whether they are doing better than they were before care for tinnitus was provided. Ideally, the outcome assessment would be conducted by someone other than the clinician who provided the intervention., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Noise sensitivity and hyperacusis are decreased sound tolerance conditions that are not well delineated or defined. This paper presents the correlations and distributions of the Noise Sensitivity Scale (NSS) and the Hyperacusis Questionnaire (HQ) scores in two distinct large samples. In Study 1, a community-based sample of young healthy adults (n = 103) exhibited a strong correlation (r = 0.74) between the two questionnaires. The mean NSS and HQ scores were 54.4 ± 16.9 and 12.5 ± 7.5, respectively. NSS scores displayed a normal distribution, whereas HQ scores showed a slight positive skew. In Study 2, a clinical sample of Veterans with or without clinical comorbidities (n = 95) showed a moderate correlation (r = 0.58) between the two questionnaires. The mean scores were 66.6 ± 15.6 and 15.3 ± 7.3 on the NSS and HQ, respectively. Both questionnaires' scores followed a normal distribution. In both samples, participants who self-identified as having decreased sound tolerance scored higher on both questionnaires. These findings provide reference data from two diverse sample groups. The moderate to strong correlations observed in both studies suggest a significant overlap between noise sensitivity and hyperacusis. The results underscore that NSS and HQ should not be used interchangeably, as they aim to measure distinct constructs, however to what extent they actually do remains to be determined. Further investigation should distinguish between these conditions through a comprehensive psychometric analysis of the questionnaires and a thorough exploration of psychoacoustic, neurological, and physiological differences that set them apart., (Copyright © 2024 The Author(s).

Tinnitus acoustic therapy is defined as any use of sound where the intent is to alter the tinnitus perception and/or the reactions to tinnitus in a clinically beneficial way. The parameters of sound that may cause beneficial effects, however, are currently only theorized with limited data supporting their effectiveness. Residual inhibition is the temporary suppression or elimination of tinnitus that is usually observed following appropriate auditory stimulation. Our pilot study investigated the effects of a therapeutic acoustic stimulus that was individually customized to maximize residual inhibition of tinnitus and extend its duration to determine if there could be a sustained suppression of the tinnitus signal (i.e., reduced tinnitus loudness) and a reduction in the psychological and emotional reactions to tinnitus. This pilot study had two objectives: (1) to evaluate the feasibility of residual inhibition technique therapy through daily use of hearing aids and (2) to determine its effects by measuring reactionary changes in tinnitus with the Tinnitus Functional Index (TFI) and perceptual changes in tinnitus loudness. A total of 20 adults (14 males, 6 females; mean age: 58 years, SD = 12.88) with chronic tinnitus were enrolled in a four-visit study that consisted of the following: (1) baseline visit and initiation of the intervention period, (2) a 1-month postintervention visit, (3) 2-month postintervention visit and initiation of a wash-out period, and (4) a 3-month visit to assess the wash-out period and any lasting effects of the intervention. The intervention consisted of fitting bilateral hearing aids and creating an individualized residual inhibition stimulus that was streamed via Bluetooth from a smartphone application to the hearing aids. The participants were instructed to wear the hearing aids and stream the residual inhibition stimulus all waking hours for the 2-month intervention period. During the wash-out period, the participants were instructed to use the hearing aids for amplification, but the residual inhibition stimulus was discontinued. At all visits, the participants completed the TFI, study-specific self-report measures to document perceptions of tinnitus, a psychoacoustic test battery consisting of tinnitus loudness and pitch matching, and a residual inhibition test battery consisting of minimum masking and minimum residual inhibition levels. At the end of the trial, participants were interviewed about the study experience and acceptability of the residual inhibition treatment technique. Repeated measures analyses of variance (ANOVA) were conducted on the two main outcomes (TFI total score and tinnitus loudness) across all four visits. The results showed a significant main effect of visit on the TFI total score ( p  < 0.0001). Specifically, the results indicated a significant reduction in TFI total scores from baseline to the 1-month post-intervention period, which remained stable across the 2-month post-intervention period and the wash-out period. The ANOVA results did not show a significant change in tinnitus loudness as a function of visit ( p  = 0.480). The majority of the participants reported a positive experience with the study intervention at their exit interview. This pilot study demonstrated that residual inhibition as a sound therapy for tinnitus, specifically through the daily use of hearing aids, was feasible and acceptable to individuals suffering from chronic tinnitus. In addition, participants showed improvement in reactions to tinnitus as demonstrated by sustained reduction in TFI scores on average over the course of the treatment period. Achieving residual inhibition may also provide patients a feeling of control over their tinnitus, and this may have a synergistic effect in reducing the psychological and emotional distress associated with tinnitus. There was no significant reduction in long-term tinnitus loudness resulting from the residual inhibition treatment; however, the current pilot study may not have had sufficient power to detect such a change. The combination of tinnitus suppression and improved psychosocial/emotional reactions to tinnitus may result in a better quality of life in both the short and long term. A larger-scale study is needed to determine the validity of using residual inhibition as a clinical therapy option and to ascertain any effects on both perception and reactions to tinnitus., Competing Interests: Conflict of Interest Hearing aids and hearing aid supplies (i.e., domes, batteries, cleaning materials) were donated by GN ReSound.

Purpose: The Tinnitus Screener was introduced in 2015 as a four-item algorithmic instrument to assess the temporal characteristics of a person's reported tinnitus. The Tinnitus Screener was then revised as a six-item version to include a new temporal category and to capture tinnitus duration (acute < 6 months vs. chronic ≥ 6 months). When contrasted with audiologist assessment, the four-item Tinnitus Screener was determined to be highly valid, but the short-term reliability of either version remained unknown. The present analysis focused on determining the test-retest reliability of the six-item Tinnitus Screener. Additionally, we sought to determine whether reliability differed by respondent age, sex, military status, and hearing loss., Method: The Tinnitus Screener was administered to 190 military Service members and 250 military Veterans at two time points separated by 7-31 days. Our analysis focused on test-retest reliability of responses as measured by the kappa coefficient, overall and within subsamples. Percent agreement of tinnitus categorization (temporal categories) and classification (positive/negative) between the two time points was also evaluated., Results: Constant or intermittent tinnitus was found in 31% of Service members and 53% of Veterans. Overall, kappa reliability coefficients were high, near .80, indicating substantial reliability. The majority (96%) of reliability coefficients for the Tinnitus Screener within subsamples were similarly high, ranging from .68 to .88., Conclusions: The updated version of the Tinnitus Screener is shown to be a reliable instrument. The Tinnitus Screener is recommended to inform clinical decision making by determining the temporal characteristics of tinnitus.

Purpose: The purpose of this study was to examine progressive tinnitus management (PTM) Level 3 skill utilization among Veterans in the Bay Pines Veterans Affairs Healthcare System 6-10 years after completing the PTM workshops., Method: In fiscal year 2020, the Tinnitus Workshop Follow-Up form was mailed to Veterans who completed the workshops during fiscal years 2010-2014. Veterans were identified as receiving care via the traditional face-to-face method or clinical video telehealth (CVT). Data were compiled to determine which, if any, PTM skills were being used 6-10 years later and the impact on self-reported ratings of well-being., Results: More than half of the respondents reported using all four self-management skills up to 10 years postcompletion; relaxation was utilized by more Veterans than the other three skills. Approximately 69% reported improved ability to control reactions to tinnitus. At least half reported ratings of improved well-being. Eighty-eight percent of the respondents said they would recommend the workshops to someone with bothersome tinnitus. Veterans who received care via CVT reported using fewer skills than those who received care face-to-face; however, the CVT respondents reported the same or slightly better ability to cope with tinnitus, less bothersome tinnitus, and improved ratings of well-being. Finally, most participants who responded to an open-ended question about their workshop experience reported it as positive., Conclusions: This clinical focus project suggests that PTM Level 3 skills continue to be utilized up to 10 years after participation in the workshops. Although there were reductions in the number of skills used, Veterans' ability to manage reactions to tinnitus and improvement in self-reported ratings of well-being indicate successful ongoing tinnitus management efforts. Respondents who received care via CVT did not report lower self-reported ratings of well-being or appear less likely to recommend Level 3 group PTM to other Veterans with bothersome tinnitus.

Audiologists' role in providing care for tinnitus typically includes conducting an audiologic evaluation, fitting hearing aids when appropriate, assessing the impact of tinnitus, and facilitating use of sound to improve quality of life with tinnitus when appropriate. Cognitive behavioral therapy (CBT) is consistently judged by systematic reviews as having the strongest evidence relative to other therapies for improving quality of life with tinnitus. Because audiologists are already playing an active role in providing care for tinnitus, and the relative paucity of behavioral health providers who are experienced in implementing CBT for tinnitus, a logical question is whether audiologists can provide CBT and whether it is within their scope of practice. In this article, we present both sides of the argument as to whether audiologists can provide CBT and we make recommendations for appropriate administration of CBT for tinnitus management., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objectives: Military Service members and Veterans commonly report hearing loss and tinnitus, both of which can result in significant disability. During military service, Service members are exposed to many different types of loud noise, which is strongly associated with hearing loss and tinnitus. Other military-related exposures, such as chemicals and traumatic brain injury (TBI), are also linked with auditory problems. The purpose of the "Noise Outcomes in Servicemembers Epidemiology" (NOISE) study is to gather information from Active-Duty Service members and recently separated Veterans about their military and nonmilitary noise exposures, other relevant military and nonmilitary exposures, and potential outcomes of these exposures including tinnitus, hearing loss, and other hearing-related health concerns., Design: The NOISE study assesses lifetime noise exposures, chemical and blast exposures, TBI, physical and psychiatric comorbidities, and other military and nonmilitary exposures and outcomes that can affect auditory function. Participants undergo comprehensive in-person audiologic examinations; those who experience tinnitus undergo a complete tinnitus assessment. Exposures and select outcomes are reassessed annually by mail, and the comprehensive in-person assessment is completed every 5 years. This report presents descriptive, baseline data obtained from the first 690 participants enrolled between 2014 and 2018., Results: Some notable findings from this analysis include: (1) the prevalence of hearing loss in the sample was 8% for low frequencies (0.25 to 2 kHz), 20% for high frequencies (3 to 8 kHz), and 39% for extended high frequencies (9 to 16 kHz); (2) the prevalence of tinnitus was 53%; (3) the prevalence of both hearing loss and tinnitus was higher among those with higher age, more years of military service, greater degree of noise exposure, and exposures to blasts and/or TBI in the military; and (4) tinnitus was most prevalent among participants who serve/served in the Army relative to the other military branches., Conclusions: The NOISE study is acquiring comprehensive data on military-related auditory dysfunction. It is the first of its kind to enroll active Service members and recently separated Veterans into a longitudinal study to examine the etiology and outcomes of tinnitus and hearing loss in this population. Although these data do not necessarily represent the entire military and Veteran populations, ongoing enrollment is focused on increasing generalizability and will also provide the statistical power to conduct multivariable analyses. This will allow us to examine longitudinal associations of interest while controlling for potential confounders and other possible sources of error. These data will provide critical knowledge to refine future military hearing conservation efforts and inform efforts to develop future treatments., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

Purpose: Progressive Tinnitus Management (PTM) is an evidence-based interdisciplinary stepped-care approach to improving quality of life for patients with tinnitus. PTM was endorsed by Department of Veterans Affairs (VA) Audiology leadership in 2009. Factors affecting implementation of PTM are unknown. We conducted a study to: 1) estimate levels of PTM program implementation in VA Audiology and Mental Health clinics across the country; and 2) identify barriers and facilitators to PTM implementation based on the experiences of VA audiologists and mental health providers., Method: We conducted an anonymous, web-based survey targeting Audiology and Mental Health leaders at 144 major VA facilities. Quantitative analyses summarized respondents' facility characteristics and levels of program implementation (full PTM, partial PTM, or no PTM). Qualitative analyses identified themes in factors influencing the implementation of PTM across VA sites., Results: Surveys from 87 audiologists and 66 mental health clinicians revealed that few facilities offered full PTM; the majority offered partial or no PTM. Inductive analysis of the open-ended survey responses identified seven factors influencing implementation of PTM: 1) available resources, 2) service collaboration, 3) prioritization, 4) Veterans' preferences and needs, 5) clinician training, 6) awareness of (evidence-based) options, and 7) perceptions of scope of practice., Conclusion: Results suggest wide variation in services provided, a need for greater engagement of mental health providers in tinnitus care, and an interest among both audiologists and mental health providers in receiving tinnitus-related training. Future research should address barriers to PTM implementation, including methods to: 1) improve understanding among mental health providers of their potential role in tinnitus management; 2) enhance coordination of tinnitus-related care between health care disciplines; and 3) collect empirical data on Veterans' need for and interest in PTM, including delivery by telehealth modalities., Competing Interests: The authors have read the journal’s policy and have the following conflicts: JH, TZ, and CS were part of the research team that originally developed Progressive Tinnitus Management.

Tinnitus is commonly referred to as "ringing in the ears." Epidemiologic studies highlight challenges associated with clinical determination of tinnitus and ascertainment of its etiology, functional effects, temporal characteristics, psychoacoustic parameters, and risk factors. Because no standards exist for capturing these factors as measures, direct comparison of data between studies is not possible. This report suggests terminology and definitions to promote standardization, with a brief overview of findings from selected population-based epidemiologic studies. Tinnitus-specific data are presented from the Noise Outcomes in Servicemembers Epidemiology study. Further epidemiologic studies are needed to develop tinnitus treatment and a cure for this chronic condition., Competing Interests: Disclosure This work was supported by a Department of Defense Congressionally Directed Medical Research Program Investigator-Initiated Research Award (PR121146), a Joint Warfighter Medical Research Program Award (JW160036), and a US VA Rehabilitation Research and Development (RR&D) Research Career Scientist Award (1 IK6 RX002990-01).

Purpose Psychoacoustic characteristics of tinnitus include its loudness and pitch. These characteristics are commonly measured and reported; however, it has not been shown that they are associated with the impact, or bothersomeness, of tinnitus. This study addressed this question by determining correlations between measures of tinnitus loudness, tinnitus pitch, and functional effects of tinnitus. Method Tinnitus loudness matches, pitch matches, a numeric rating scale (NRS) of tinnitus loudness, and responses to the 25-item tinnitus functional index (TFI) were obtained from 223 participants who experienced tinnitus for at least 6 months. Estimates of tinnitus pitch were calculated by use of a Bayesian sequential analysis technique. Results The total TFI score, as well as each of its 8 subscales, had weak or no correlations with both loudness matches and pitch matches, but moderate correlations with the NRS. Conclusions Psychoacoustic measurements used to estimate aspects of tinnitus perception appear unrelated to the impact of tinnitus, as assessed by a subjective outcome instrument. These psychoacoustic measurements do not assess reactions to tinnitus. These reactions should be measured by validated questionnaires, such as the TFI, which are designed to measure tinnitus impact. The moderate correlations between the NRS and the TFI suggest that self-reported tinnitus loudness is more a measure of tinnitus reactions than perception.

Purpose Tinnitus is prevalent among military Veterans and may frequently co-occur with mental health disorders. This study examined health care utilization and mental health diagnoses among Veterans with and without tinnitus who receive Department of Veterans Affairs (VA) health care. Method We randomly sampled 10% of VA health care users for a 5-year period between 2011 and 2016. Tinnitus and other diagnoses were identified using International Classification of Diseases diagnosis codes; Veterans assigned 1 or more inpatient codes or 2 or more outpatient codes were considered to have the respective diagnosis. We examined demographics, military service, clinical characteristics, and health care utilization of Veterans with and without tinnitus diagnoses. Bivariable and multivariable logistic regression was used to estimate associations between tinnitus and mental health diagnoses of interest. Results Among 617,534 eligible Veterans, 3.8% met criteria for tinnitus diagnosis. Prevalence of tinnitus was associated with sex, age, race, marital status, and VA service connection status; additionally, hearing loss and traumatic brain injury were frequently codiagnosed with tinnitus. Veterans with tinnitus had higher annual health care utilization than those without. While controlling for potential confounders, tinnitus diagnoses were associated with mental health diagnoses, including anxiety, depression, and substance use disorders. Conclusion Findings suggest that Veterans who are diagnosed with tinnitus have more health care utilization and are more frequently diagnosed with mental health disorders than Veterans who are not diagnosed with tinnitus. This suggests a need for coordinated tinnitus and mental health care services for Veterans in the VA system of care.

Purpose This is a description of the clinical implementation and outcomes of progressive tinnitus management (PTM) at 2 Veterans Affairs (VA) medical centers: Both programs modified the protocol originally described by PTM developers. Method Modifications at both sites were classified according to an evidence-based framework set forth by Stirman, Miller, Toder, and Calloway (2013) . The Iowa City VA PTM program clinicians made 2 modifications and the Asheville, North Carolina, VA PTM program clinicians made 6 modifications to the standard PTM protocol. Pre-post outcome measures were analyzed for 20 veterans who completed the Iowa City program and for 200 veterans who completed the Asheville program. Results Veterans who completed the Iowa City program showed a statistically significant decrease in the average Tinnitus Handicap Inventory score ( Newman, Jacobson, & Spitzer, 1996 ). Veterans who completed the Asheville PTM program showed a statistically significant decrease in the average Tinnitus Functional Index (TFI) score. Outcomes in Asheville were compared to outcomes of a clinical trial of PTM conducted by the developers of PTM. The clinical work in Asheville resulted in a greater mean reduction on the TFI and a larger effect size using the TFI as compared to the results of the PTM clinical trial. Conclusions Clinician-directed modifications to PTM that are made to address the unique needs and circumstances of an individual clinic have potential to result in positive outcomes for patients. Clinicians providing care for patients with tinnitus using PTM who modify the protocol to meet the needs of their local setting are encouraged to collect and report the outcomes of their modifications to improve understanding of the impact of various types of modifications to PTM and other evidence-based practices.

Objectives: This randomized controlled trial evaluated the efficacy of delivering coping skills education from Progressive Tinnitus Management (PTM) by telephone (Tele-PTM). The trial followed a previous pilot study that showed positive results for Tele-PTM., Design: Participants included individuals with bothersome tinnitus (N = 205) located anywhere within the United States. A special emphasis was given to including individuals who had experienced one or more traumatic brain injuries (TBIs). Participants were randomized to either Tele-PTM intervention or 6-month wait-list control (WLC). The Tele-PTM intervention involved five telephone appointments-two led by an audiologist (teaching how to use therapeutic sound) and three by a psychologist (teaching coping skills derived from cognitive-behavioral therapy). It was hypothesized that Tele-PTM would be more effective than WLC in reducing functional effects of tinnitus as measured with the Tinnitus Functional Index. Additional outcome measures included the Self-Efficacy for Managing Reactions to Tinnitus questionnaire and the Hospital Anxiety and Depression Scale. The effect of Tele-PTM on outcomes was estimated using linear mixed models., Results: Overall results showed convincingly that the Tele-PTM group had significantly better outcomes than the WLC group. These results were consistent across all outcome measures, indicating not only a reduction of tinnitus functional distress but also increased self-efficacy. Improvements in measures of anxiety and depression were also observed. Tele-PTM participants in all TBI categories showed significant improvement., Conclusions: Results provide strong support for use of Tele-PTM methodology for persons with bothersome tinnitus, regardless of whether the person also has TBI symptoms. The effect size for Tele-PTM was high for the primary outcome measure, the Tinnitus Functional Index, and all other outcome measures showed significant improvement. Combined with our previous pilot study, the Tele-PTM method is validated for potential nationwide provision of tinnitus services.

Objectives: The Noise Outcomes in Servicemembers Epidemiology (NOISE) Study is obtaining longitudinal data to evaluate the effects of noise and other exposures on auditory function in military personnel. A gap in the literature is the lack of studies concerning how active-duty Service members might be impacted by having tinnitus. The present study reports NOISE Study data that address this gap., Methods: Data are reported from current Service members and recently-separated (within 2.5 years) Veterans, enabling a direct comparison of results between active and post-military samples. Data were collected from two sites: VA Portland Health Care System, Portland, OR and Department of Defense Hearing Center of Excellence, San Antonio, TX. Participants completed comprehensive audiometric testing and numerous questionnaires., Results: Results are presented from n = 428 participants across the two sites, including 246 Veterans and 182 Service members. The data reveal that, for both Service members and Veterans, the presence of tinnitus has effects on job performance, concentration, anxiety, depression, and sleep., Conclusions: This study has revealed that, for these samples of study participants, tinnitus has an impact on military Service members that is comparable to how it affects Veterans who have completed their military service within the previous 2.5 years., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2019.

Objective: This study obtained preliminary data using two types of sound therapy to suppress tinnitus and/or reduce its functional effects: (1) Notched noise (1000-12,000 Hz notched within a 1-octave range centred around the tinnitus pitch match [PM] frequency); and (2) Matched noise (1-octave wide band of noise centred around the PM frequency). A third (Placebo) group listened to low frequency noise (250-700 Hz)., Design: Participants with bothersome tinnitus were randomised into one of the three groups and instructed to listen to the acoustic stimulus for 6 hours a day for 2 weeks. Stimuli were delivered using an iPod Nano, and tinnitus counselling was not performed. Outcome measures were recorded at the 0, 2 and 4 week study visits., Study Sample: Thirty participants with constant and bothersome tinnitus were recruited and randomised., Results: All groups showed, on average, overall improvement, both immediately post-treatment and 2 weeks following treatment. Outcomes varied between groups on the different measures and at the two outcome points., Conclusion: This study showed improvement for all of the groups, lending support to the premise that any type of sound stimulation is beneficial for relieving effects of tinnitus. These results may serve as a preliminary evidence for a larger study.

Purpose: The primary purpose of this study was to determine whether progressive tinnitus management Level 3 skills education workshops conducted at the Bay Pines and Boston Veterans Affairs hospitals result in consistent use of the presented tinnitus management strategies by patients 1-5 years after completing the workshops., Method: In fiscal year (FY) 2015, the tinnitus workshop follow-up form was mailed to all veterans who completed the Level 3 workshops between FY 2010 and FY 2014. Data were compiled to determine which, if any, of the skills taught in the workshops were being used 1-5 years after completion of the workshops and the impact on quality-of-life indicators., Results: All self-management skills were being utilized up to 5 years postcompletion; therapeutic sound was utilized the most. The majority of patients reported an improved ability to manage reactions to tinnitus and improved quality-of-life indicators. Over 90% of patients from both sites recommended the program to others with tinnitus., Conclusion: The self-management skills taught in the progressive tinnitus management Level 3 workshops are sustained over time even when limited resources prevent the full complement of workshops or the involvement of mental health services. The workshops can also be successfully implemented through remote delivery via videoconferencing (telehealth)., Supplemental Materials: https://doi.org/10.23641/asha.5370883.

Military Service Members are often exposed to high levels of occupational noise, solvents, and other exposures that can be damaging to the auditory system. Little is known about hearing loss and how it progresses in Veterans following military service. This epidemiology study is designed to evaluate and monitor a cohort of Veterans for 20 years or more to determine how hearing loss changes over time and how those changes are related to noise exposure and other ototoxic exposures encountered during military service. Data reported here are from baseline assessments of the first 100 study participants (84 males; 16 females; mean age 33.5 years; SD 8.8; range 21-58). Each participant was asked to complete a comprehensive audiologic examination and self-report questionnaires regarding sociodemographic characteristics, noise and solvent exposures, health conditions common among post-deployment Veterans, and the social and emotional consequences of hearing loss. For this relatively young cohort, 29% exhibited hearing loss, defined as average hearing threshold >20 dB HL in the conventional audiometric range. Forty-two percent exhibited hearing loss in the extended-high-frequency audiometric range using the same criterion (average hearing threshold >20 dB HL). Certain factors were found to be associated with poorer hearing in both conventional and extended-high-frequency ranges, including age, type of military branch, years of military service, number of military deployments, noise exposure, tinnitus, and a positive screen for post-traumatic stress disorder. Although the majority of participants had hearing within normal limits, 27% reported a self-perceived mild/moderate hearing handicap and 14% reported a significant handicap. Further research is needed to identify a cause for this discrepancy in audiologic results versus self-report. The information obtained from this longitudinal study could be used in future resource planning with the goal of preventing, as much as possible, the development of hearing loss during military service, and the exacerbation of prevalent hearing loss after military service and over Veterans' lifetimes., (Published by Elsevier B.V.)

Purpose: This randomized controlled trial evaluated, within clinical settings, the effectiveness of coping skills education that is provided with progressive tinnitus management (PTM)., Method: At 2 Veterans Affairs medical centers, N = 300 veterans were randomized to either PTM intervention or 6-month wait-list control. The PTM intervention involved 5 group workshops: 2 led by an audiologist (teaching how to use sound as therapy) and 3 by a psychologist (teaching coping skills derived from cognitive behavioral therapy). It was hypothesized that PTM would be more effective than wait-list control in reducing functional effects of tinnitus and that there would be no differences in effectiveness between sites., Results: At both sites, a statistically significant improvement in mean Tinnitus Functional Index scores was seen at 6 months for the PTM group. Combined data across sites revealed a statistically significant improvement in Tinnitus Functional Index relative to wait-list control. The effect size for PTM using the Tinnitus Functional Index was 0.36 (small)., Conclusions: Results suggest that PTM is effective at reducing tinnitus-related functional distress in clinical settings. Although effect sizes were small, they provide evidence of clinical effectiveness of PTM in the absence of stringent research-related inclusion criteria and with a relatively small number of sessions of cognitive behavioral therapy.

Purpose: A retrospective analysis of tonal and speech loudness discomfort levels (LDLs) relative to a subjective report of sound tolerance (SRST) was performed to explore the relation between the 2 commonly used clinical measures., Method: Tonal LDLs and SRST were measured for 139 U.S. military veterans who were recruited into a study providing intervention for tinnitus. Spearman's rank correlation coefficients were computed to assess the relation between the tonal and speech LDLs and the SRST., Results: Only weak correlations were found between tonal LDLs and SRST and between speech LDLs and SRST., Conclusion: If LDLs ratings of SRST measured the same phenomenon, the measures would be strongly negatively correlated. The weak correlations found between the measures suggest that LDLs do not accurately represent a patient's ability to tolerate sound in daily life.

Objectives: New tinnitus therapies are being developed and marketed that target the patient's tinnitus frequency. This frequency is estimated clinically by pitch matching, which has the patient identify the pure tone that is closest to the perceived tinnitus frequency. Though widely used, pitch matching is heavily criticized as unreliable, and the degree of reliability varies among patients. At the very least, it is recommended that multiple pitch matches be used to identify the patient's tinnitus frequency. Even so, it is not clear how many pitch matches to collect, how they should be combined, or how doing so will enhance the audiologist's certainty about the true tinnitus frequency. In this article, we describe a simple Bayesian method of sequentially combining pitch matches until acceptable precision is achieved and illustrate the method in 10 patients with chronic tinnitus., Design: Subjects were recruited from previous study participants and support group attendees at the National Center for Rehabilitative Auditory Research. Thirty tinnitus pitch matches were elicited from 10 patients with chronic, monotonal tinnitus., Results: A Bayesian sequential analysis yielded estimated tinnitus frequencies for 7 patients that were within one-quarter octave of their true value with 90% certainty. Between four and twenty pitch matches were required to achieve acceptable results in these seven patients., Conclusions: Despite criticism, pitch matching is widely used to estimate tinnitus frequency. We address reliability concerns with a Bayesian sequential analysis to jointly estimate tinnitus frequency and reliability. The method is easily applied.

Background: Evaluation tools are lacking for the identification of patients exhibiting pseudotinnitus. It was hypothesized that tinnitus loudness traces might show a separation between continuous and pulsed tones for participants exhibiting pseudotinnitus, that is, the "type V" pattern shown for threshold tracking among participants exhibiting pseudohypacusis. It was further hypothesized that tinnitus loudness tracking might reveal unreliable tinnitus loudness matches among participants exhibiting pseudotinnitus due to their lack of an internal tinnitus standard., Purpose: To determine whether a tinnitus loudness tracking pattern exists for participants exhibiting pseudotinnitus., Research Design: Nonrandomized posttest-only control design. The experimental group participants were those without tinnitus, and the control group participants were those with tinnitus., Study Sample: There were 86 participants, including 45 with tinnitus and 41 without tinnitus. The participants' hearing varied from normal to severe hearing losses by pure-tone average at 1000, 2000, and 4000 Hz., Intervention: Participants without tinnitus were asked to act as if they had tinnitus and to complete tinnitus loudness matching as if they were trying to convince the test (or computer) that they had tinnitus., Data Analysis: t-tests, Results: There were no statistically significant differences between individuals with tinnitus and participants acting out pseudotinnitus for any of six measures: (1) continuous tone tinnitus loudness tracking; (2) pulsed tone tinnitus loudness tracking; (3) differences between continuous and pulsed tone tinnitus loudness tracking; (4) continuous tone excursion width; (5) pulsed tone excursion width; and (6) differences between continuous and pulsed tone excursion width., Conclusions: Tinnitus loudness tracking does not appear to hold promise as a clinical tool for the identification of participants exhibiting pseudotinnitus., (American Academy of Audiology.)

Background: Psychoacoustic measures of tinnitus typically include loudness and pitch match, minimum masking level (MML), and residual inhibition (RI). We previously developed and documented a computer-automated tinnitus evaluation system (TES) capable of subject-guided loudness and pitch matching. The TES was further developed to conduct computer-aided, subject-guided testing for noise-band matching (NBM), MML, and RI., Purpose: The purpose of the present study was to document the capability of the upgraded TES to obtain measures of NBM, MML, and RI, and to determine the test-retest reliability of the responses obtained., Research Design: Three subject-guided, computer-automated testing protocols were developed to conduct NBM. For MML and RI testing, a 2-12 kHz band of noise was used. All testing was repeated during a second session., Study Sample: Subjects meeting study criteria were selected from those who had previously been tested for loudness and pitch matching in our laboratory. A total of 21 subjects completed testing, including seven females and 14 males., Results: The upgraded TES was found to be fairly time efficient. Subjects were generally reliable, both within and between sessions, with respect to the type of stimulus they chose as the best match to their tinnitus. Matching to bandwidth was more variable between measurements, with greater consistency seen for subjects reporting tonal tinnitus or wide-band noisy tinnitus than intermediate types. Between-session repeated MMLs were within 10 dB of each other for all but three of the subjects. Subjects who experienced RI during Session 1 tended to be those who experienced it during Session 2., Conclusions: This study may represent the first time that NBM, MML, and RI audiometric testing results have been obtained entirely through a self-contained, computer-automated system designed specifically for use in the clinic. Future plans include refinements to achieve greater testing efficiency., (American Academy of Audiology.)

The Department of Veterans Affairs (VA) considers tinnitus a disability. Veterans can claim tinnitus as a "service-connected" disability if the tinnitus is thought to be connected to military service. The VA adjudicates each claim and determines whether reasonable evidence exists to support it. Currently, determining the presence of tinnitus is based on subjective reporting-objective measures do not exist. The aim of this study was to develop and document a test for detecting the presence/absence of tinnitus with high confidence. Using our computer-automated, self-guided tinnitus evaluation system, we conducted three phases of testing to compare psychoacoustic measures of tinnitus between participants with versus without tinnitus. Phase 1 measures included loudness match, pitch match, minimum masking level, residual inhibition, Békésy, and forced-choice double staircase. Phases 2 and 3 measures were chosen based on results of the previous phase. The number of tests and time of testing decreased during each successive phase. Differences were seen between groups; most notably, higher low-frequency loudness matches and higher median pitch matches were observed for participants with tinnitus. Results of this study suggest that further efforts can produce a defined psychoacoustic test battery for identifying the presence/absence of tinnitus.

Tinnitus, or "ringing in the ears," affects 10%-15% of adults; cases can be problematic and require lifelong management. Many people who have experienced traumatic brain injury (TBI) also experience tinnitus. We developed Progressive Tinnitus Management (PTM), which uses education and counseling to help patients learn how to self-manage their reactions to tinnitus. We adapted PTM by delivering the intervention via telephone and by adding cognitive-behavioral therapy. A pilot study was conducted to evaluate the feasibility and potential efficacy of this approach for individuals with and without TBI. Participants with clinically significant tinnitus were recruited into three groups: probable symptomatic mild TBI (n = 15), moderate to severe TBI (n = 9), and no symptomatic TBI (n = 12). Participants received telephone counseling (six sessions over 6 months) by an audiologist and a psychologist. Questionnaires were completed at baseline, 12 weeks, and 24 weeks. All groups showed trends reflecting improvement in self-perceived functional limitations due to tinnitus. A follow-up randomized clinical study is underway.

Purpose: This study tested a prediction stemming from the hypothesis that anastrozole users experience heightened vitreo-retinal traction. This hypothesis was based on the knowledge that menopause increases the risk of intraocular tractional events such as posterior vitreous detachments (PVDs)., Methods: Retinal thickness was measured for 3 groups of amenorrheic women: (1) anastrozole users and (2) tamoxifen users undergoing adjuvant therapy for early-stage breast cancer, and (3) control subjects not using hormonal medication. Foveal shape indices were derived for subjects without PVDs., Results: For anastrozole users, the distance to the temporal side of the fovea became less than the distance to the nasal side at a sufficient height above the foveal base. This effect did not exist for control subjects; the between-group difference was appreciable. Results concerning tamoxifen users were inconclusive., Conclusions: The foveas of women using anastrozole appear to be subjected to more tractional force than are the foveas of women not using any hormonal medication.
