This paper summarises findings from studies that evaluated the benefits of bimodal fitting (combining a hearing aid and a cochlear implant in opposite ears) or bilateral cochlear implantation, relative to unilateral implantation, for children (Ching et al., 2007). On average, the size of binaural speech intelligibility advantages due to redundancy and head shadow was similar for the two bilateral conditions. An added advantage of bimodal fitting was that the low-frequency cues provided by acoustic hearing complemented the high-frequency cues conveyed by electric hearing in perception of voice and music. Some children with bilateral cochlear implants were able to use spatial separation between speech and noise to improve speech perception in noise. This is possibly a combined effect of the directional microphones in their implant systems and their ability to use spatial cues. The evidence to date supports the provision of hearing in two ears as the standard of care. Copyright © 2008 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

This paper reports interim findings of a prospective study that examines longitudinal outcomes of early- and later-identified children with hearing impairment in Australia. Eighty-seven children with cochlear implants were assessed using the Preschool Language Scale at one or more intervals. Results demonstrated that children who received a cochlear implant before 12 months of age developed normal language skills and at a rate that is comparable to normal-hearing children. Children who received later implantation performed at two standard deviations below the normative mean. These results are preliminary, as there are currently insufficient data to examine the effect of multiple factors on language outcomes and the rate of language development.

This article aims to (1) examine the impact of newborn hearing screening on age of hearing aid fitting, and (2) estimate the prevalence of permanent childhood hearing impairment and its profile across age and degree of impairment in Australia. The data were drawn from the Australian Hearing national database on all aided children under 21 years of age as at December 2006. The results indicated that children who were screened and diagnosed soon after birth were fitted by a median age of 3.4 months in New South Wales. The prevalence of moderate and more severe hearing loss (three-frequency average in the better ear of ≥ 40 dB HL) rises from 1.04/1000 live births at 3 years of age to 1.57/1000 live births for children between 9 and 16 years of age. The prevalence of mild degrees of hearing loss (three-frequency average in the better ear < 40 dB HL) rises from 0.28/1000 live births at 3 years of age to 1.68/1000 live births at 9 years of age and older. The findings show that early detection leads to early amplification. The change in prevalence with age implies that newborn hearing screening needs to be supplemented by hearing screening at later ages of early childhood so that timely amplification can be provided.

This paper focuses on how the acoustical differences between the ear canals of adults and children affect amplification requirements and describes efficient strategies to allow for these differences when prescribing and verifying amplification. We will first summarize the problem for hearing assessment and then describe how adult-equivalent hearing loss can be calculated to circumvent this problem. Example cases demonstrate manual calculation and automatic derivation by using the NAL-NL1 software. The advantage of using real-ear aided gain prescriptions rather than real-ear insertion gain prescriptions for young children is explained. The practical benefit of deriving coupler gain targets to achieve the required real-ear aided gain by using individually measured real-ear-to-coupler differences is emphasized, together with a discussion on the practical issues relating to calibration and probe tube placement in measuring real-ear-to-coupler differences. Finally, an illustrative case exemplifies the derivation of individualized coupler gain targets by using the NAL-NL1 software system to achieve the required real-ear aided gain for a young child.

This article discusses whether children who did not wear a hearing aid after implantation would benefit from using a hearing aid using a cochlear implant in opposite ears. There is increasing evidence on the binaural benefits achievable with the use of hearing aids with cochlear implants in opposite ears for children who have continued to wear a hearing aid with a cochlear implant after implantation. This study aimed to evaluate whether children who received a unilateral cochlear implant but did not continue to wear a hearing aid in the opposite ear for up to eight years would benefit from using a cochlear implant with a hearing aid.

BACKGROUND: Universal newborn hearing screening was implemented worldwide largely on modeled, not measured, long-term benefits. Comparative quantification of population benefits would justify its high cost. METHODS: Natural experiment comparing 3 population approaches to detecting bilateral congenital hearing loss (>25 dB, better ear] in Australian states with similar demographics and services: (1) universal newborn hearing screening, New South Wales 2003-2005, n = 69; (2) Risk factor screening (neonatal intensive care screening + universal risk factor referral), Victoria 2003-2005, n = 65; and (3) largely opportunistic detection, Victoria 1991-1993, n - 86. Children in (1) and (2) were followed at age 5 to 6 years and in (3} at 7 to 8 years. Outcomes were compared between states using adjusted linear regression. RESULTS: Children were diagnosed younger with universal than risk factor screening (adjusted mean difference -8.0 months, 95% confidence interval -12.3 to -3.7). For children without intellectual disability, moving from opportunistic to risk factor to universal screening incrementally improved age of diagnosis (22.5 vs 16.2 vs 8.1 months, P < .001), receptive (81.8 vs 83.0 vs 88.9, P = .05) and expressive (74.9 vs 80.7 vs 89.3, P < .001) language and receptive vocabulary (79.4 vs 83.8 vs 91.5, P < .001); these nonetheless remained well short of cognition (mean 103.4, SD 15.2). Behavior and health-related quality of life were unaffected. CONCLUSIONS: With new randomized trials unlikely, this may represent the most definitive population-based evidence supporting universal newborn hearing screening. Although outperforming risk factor screening, school entry language still lagged cognitive abilities by nearly a SD. Prompt intervention and efficacy research are needed for children to reach their potential. [ABSTRACT FROM AUTHOR]

- Abstract
Objectives: To investigate the effects of automatic scene classification (SCAN) on speech perception in noise and real-world functional performance in children using cochlear implants (CIs)., Methods: We used a within-subjects repeated measures design in two studies. The first study assessed speech perception in noise with or without SCAN enabled in 25 school-aged children. The second study evaluated functional auditory performance in real life. Parents of 18 children provided ratings using the Parents' Evaluation of Aural/oral Performance of Children (PEACH) questionnaire; and children provided ratings using the Self Evaluation of Listening Function (SELF) questionnaire. Analyses of variance with repeated measures were used to examine the effect of SCAN., Results: On average, speech perception in noise was significantly better with SCAN enabled (mean SRT: -4.1 dB; SD: 4.0), compared to SCAN disabled (mean SRT: 0.5 dB; SD: 3.5). Children's functional performance in real life was similar between the two device settings., Conclusion: Automatic auditory scene classification provides significant benefits for speech perception in noise (4.6 dB improvement). On average, there were no perceived detrimental or beneficial effects in real life. These findings support the use of SCAN in CIs for young children.

- Abstract
Objectives: Carers of children with disabilities, especially primary carers, tend to have poorer labor market outcomes than carers of typically developing children. However, the extant literature has been largely silent on whether interventions for children's disabilities spill over to carers' employment outcomes, if at all. We aimed to fill this gap., Design: We analyzed data from the Longitudinal Outcomes of Children with Hearing Impairment study, which is a unique panel dataset of Australian children who are deaf or hard-of-hearing (DHH). The Longitudinal Outcomes of Children with Hearing Impairment dataset includes information about 449 DHH children. We used 3 waves covering the same children at ages 0 to 3, 5 to 7, and 8 to 10 years during 2005 and 2018. We used a panel random-effects model, the use of which was supported by the Hausman specification test to control for time-invariant individual heterogeneity., Results: We found that primary carers (typically mothers) of DHH children with cochlear implants (CI) were more likely to be employed relative to DHH children without a CI. The positive association was stronger among carers from a lower socioeconomic background., Conclusions: The association between childhood CI and carer employment may potentially be due to relaxed primary carers' time constraints to care for the child, increased self-efficacy, and reduced carer stress, enabling them to engage in other activities, including employment. Further research through large-scale, longitudinal studies is warranted to solidify the findings of this research., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Editor's Note: The following article discusses the timely topic Clinical Guidance in the areas of Evidence-Based Early Hearing Detection and Intervention Programs. This article aims to discuss areas of services needed, guidance to countries/organizations attempting to initiate early hearing detection and intervention systems. Expert consensus and systematic/scoping reviews were combined to produce recommendations for evidence-based clinical practice. In Ear and Hearing, our long-term goal for the Point of View article is to stimulate the field's interest in and to enhance the appreciation of the author's area of expertise. Hearing is an important sense for children to develop cognitive, speech, language, and psychosocial skills. The goal of universal newborn hearing screening is to enable the detection of hearing loss in infants so that timely health and educational/therapeutic intervention can be provided as early as possible to improve outcomes. While many countries have implemented universal newborn hearing screening programs, many others are yet to start. As hearing screening is only the first step to identify children with hearing loss, many follow-up services are needed to help them thrive. However, not all of these services are universally available, even in high-income countries. The purposes of this article are (1) to discuss the areas of services needed in an integrated care system to support children with hearing loss and their families; (2) to provide guidance to countries/organizations attempting to initiate early hearing detection and intervention systems with the goal of meeting measurable benchmarks to assure quality; and (3) to help established programs expand and improve their services to support children with hearing loss to develop their full potential. Multiple databases were interrogated including PubMed, Medline (OVIDSP), Cochrane library, Google Scholar, Web of Science and One Search, ERIC, PsychInfo. Expert consensus and systematic/scoping reviews were combined to produce recommendations for evidence-based clinical practice. Eight essential areas were identified to be central to the integrated care: (1) hearing screening, (2) audiologic diagnosis and management, (3) amplification, (4) medical evaluation and management, (5) early intervention services, (6) family-to-family support, (7) D/deaf/hard of hearing leadership, and (8) data management. Checklists are provided to support the assessment of a country/organization's readiness and development in each area as well as to suggest alternative strategies for situations with limited resources. A three-tiered system (i.e., Basic, Intermediate, and Advanced) is proposed to help countries/organizations at all resource levels assess their readiness to provide the needed services and to improve their integrated care system. Future directions and policy implications are also discussed., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 The Authors.

- Abstract
Introduction: Children with early-identified unilateral hearing loss (UHL) might be at risk for delays in early speech and language, functional communication, psychosocial skills, and quality of life (QOL). However, a paucity of relevant research prohibits strong conclusions. This study aimed to provide new evidence relevant to this issue., Methods: Participants were 34 children, ages 9;0 to 12;7 (years;months), who were identified with UHL via newborn hearing screening. Nineteen children had been fitted with hearing devices, whereas 15 had not. Assessments included measures of speech perception and intelligibility; language and cognition; functional communication; psychosocial abilities; and QOL., Results and Discussion: As a group, the children scored significantly below the normative mean and more than one standard deviation below the typical range on speech perception in spatially separated noise, and significantly below the normative mean on written passage comprehension. Outcomes in other aspects appear typical. There was however considerable within participant variation in the children's degree of hearing loss over time, raising the possibility that this pattern of results might change as children get older. The current study also revealed that participants with higher levels of nonverbal ability demonstrated better general language skills and better ability to comprehend written passages. By contrast, neither perception of speech in collocated noise nor fitting with a hearing device accounted for unique variance in outcome measures. Future research should, however, evaluate the fitting of hearing devices using random assignment of participants to groups in order to avoid any confounding influence of degree of hearing loss or children's past/current level of progress., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Cupples, Ching and Hou.)

- Abstract
Purpose: The purpose of this study was to determine the speech recognition equivalence of Mandarin Bamford-Kowal-Bench (BKB) sentence lists with adults and children with normal hearing., Method: A total of 32 lists, each of nine sentences, were compiled from a corpus of BKB-like sentences with paired babble in Mandarin. Interlist equivalence, critical differences, and sensitivity of performance to signal-to-noise ratio (SNR) were examined. Experiment 1 included 64 native Mandarin-speaking adults with normal hearing. Experiment 2 included 54 native Mandarin-speaking children with normal hearing aged 4-6 years., Results: Among the 32 sentence lists, 28 lists were confirmed to be equivalent in adults, with a mean SNR required for 50% correct (SNR
50 ) of -5.9 ± 0.1 dB, a mean slope of 22.3%/dB ± 1.5%/dB, and a grand 95% critical difference subsequently calculated as 27.2% for score. From the 28 equivalent lists, 27 lists were selected and observed to be equivalent in children, with a mean SNR50 threshold of -2.0 ± 0.2 dB, a mean slope of 15.8%/dB ± 1.1%/dB, and a grand 95% critical difference of 24.6% for score., Conclusions: The Mandarin BKB sentences in babble noise test offers an opportunity for clinicians and researchers to assess speech understanding in adults and preschool children in an efficient manner. For comparisons of performance in different test conditions, 28 equivalent lists are available for adults and 27 equivalent lists for preschool children. The 95% critical difference values can be used for total percentage correct or SNR for 50% performance. Future work will examine the clinical utility for school-age children and children who are deaf and hard of hearing., Supplemental Material: https://doi.org/10.23641/asha.24400066.- Published

- Abstract
Objective: This study examined (1) the utility of a clinical system to record acoustic change complex (ACC, an event-related potential recorded by electroencephalography) for assessing speech discrimination in infants, and (2) the relationship between ACC and functional performance in real life., Methods: Participants included 115 infants (43 normal-hearing, 72 hearing-impaired), aged 3-12 months. ACCs were recorded using [szs], [uiu], and a spectral rippled noise high-pass filtered at 2 kHz as stimuli. Assessments were conducted at age 3-6 months and at 7-12 months. Functional performance was evaluated using a parent-report questionnaire, and correlations with ACC were examined., Results: The rates of onset and ACC responses of normal-hearing infants were not significantly different from those of aided infants with mild or moderate hearing loss but were significantly higher than those with severe loss. On average, response rates measured at 3-6 months were not significantly different from those at 7-12 months. Higher rates of ACC responses were significantly associated with better functional performance., Conclusions: ACCs demonstrated auditory capacity for discrimination in infants by 3-6 months. This capacity was positively related to real-life functional performance., Significance: ACCs can be used to evaluate the effectiveness of amplification and monitor development in aided hearing-impaired infants., (Copyright © 2023 International Federation of Clinical Neurophysiology.

- Abstract
Objectives: The purpose of this study was to (1) develop a Language-independent Test of Auditory Discrimination (LIT-AD) between speech sounds so that people with hearing loss who derive limited speech perception benefits from hearing aids (HAs) may be identified for consideration of cochlear implantation and (2) examine the relationship between the scores for the new discrimination test and those of a standard sentence test for adults wearing either HAs or cochlear implants (CIs)., Design: The test measures the ability of the listener to correctly discriminate pairs of nonsense syllables, presented as sequential triplets in an odd-one-out format, implemented as a game-based software tool for self-administration using a tablet computer. Stage 1 included first a review of phonemic inventories in the 40 most common languages in the world to select the consonants and vowels. Second, discrimination testing of 50 users of CIs at several signal to noise ratios (SNRs) was carried out to generate psychometric functions. These were used to calculate the corrections in SNR for each consonant-pair and vowel combination required to equalize difficulty across items. Third, all items were individually equalized in difficulty and the overall difficulty set. Stage 2 involved the validation of the LIT-AD in English-speaking listeners by comparing discrimination scores with performance in a standard sentence test. Forty-one users of HAs and 40 users of CIs were assessed. Correlation analyses were conducted to examine test-retest reliability and the relationship between performance in the two tests. Multiple regression analyses were used to examine the relationship between demographic characteristics and performance in the LIT-AD. The scores of the CI users were used to estimate the probability of superior performance with CIs for a non-CI user having a given LIT-AD score and duration of hearing loss., Results: The LIT-AD comprises 81 pairs of vowel-consonant-vowel syllables that were equalized in difficulty to discriminate. The test can be self-administered on a tablet computer, and it takes about 10 min to complete. The software automatically scores the responses and gives an overall score and a list of confusable items as output. There was good test-retest reliability. On average, higher LIT-AD discrimination scores were associated with better sentence perception for users of HAs (r = -0.54, p <0.001) and users of CIs (r = -0.73, p <0.001). The probability of superior performance with CIs for a certain LIT-AD score was estimated, after allowing for the effect of duration of hearing loss., Conclusions: The LIT-AD could increase access to CIs by screening for those who obtain limited benefits from HAs to facilitate timely referrals for CI candidacy evaluation. The test results can be used to provide patients and professionals with practical information about the probability of potential benefits for speech perception from cochlear implantation. The test will need to be evaluated for speakers of languages other than English to facilitate adoption in different countries., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 The Authors.

- Abstract
The presence of congenital permanent childhood hearing loss has a negative impact on children's development and lives. The current literature documents weaknesses in speech perception in noise and language development in many children with hearing loss. However, there is a lack of clear evidence for a longitudinal relationship between early speech perception abilities and later language skills. This study addressed the evidence gap by drawing on data collected as part of the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study. Cross-lagged regression analyses were used to examine the influence of speech perception in noise at age 5 years on language ability at age 9 years and vice versa (i.e. the influence of language ability at age 5 years on speech perception in noise at age 9 years). Data from 56 children using cochlear implants were analysed. We found that preschool speech perception in noise was a significant predictor of language ability at school age, after controlling for the effect of early language. The findings lend support to early intervention that targets the improvement of language skills, but also highlight the need for intervention and technology to enhance young children's auditory capabilities for perceiving speech in noise in early childhood so that outcomes of children with hearing loss in school can be maximized.

- Abstract
The communication journey of a child with hearing loss is often a complex, interwoven process in which the child's use of language or method of communication may change numerous times. As there has been limited research exploring the caregiver decision making process behind making such changes, this qualitative descriptive study aimed to explore the factors which influence the caregiver decision making process to change the communication method of their child with hearing loss. Individual semi-structured in-depth interviews were conducted with seven caregivers of children with hearing loss in Australia. Thematic analysis revealed five key themes which influenced caregiver decisions regarding changes to their child's method of communication, including: (1) family characteristics; (2) family access to information; (3) family strengths; (4) family beliefs; and (5) family-centered practice. The overall finding that the family unit is at the core of decision-making has important clinical implications regarding early intervention professionals' provision of family-centered services when working with the families of children with hearing loss., Competing Interests: Financial disclosure: The authors have no financial relationships relevant to this article to disclose.

- Abstract
Objective: To examine usage patterns of hearing aids and cochlear implants in children up to three years of age, how usage changes longitudinally, and factors associated with device usage., Design: Parent report and Parent's Evaluation of Aural/oral Performance of Children (PEACH) data were obtained at six and twelve months after hearing-aid fitting or cochlear implant switch-on, and again at three years of age. The effect of device use on auditory functional performance was investigated using the PEACH questionnaire., Study Sample: Four hundred and thirteen participants from the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study were included for analysis., Results: For users of hearing aids, higher usage at three years was associated with higher maternal education, and more severe hearing loss. For users of cochlear implants, higher usage was associated with higher maternal education and the absence of additional disabilities. Higher PEACH scores were associated with higher usage scores. After allowing for the effects of demographic characteristics, device use was not a significant predictor of functional performance., Conclusions: Sixty-two percent of children achieved consistent use (> 75% of waking hours) within the first year of receiving a hearing aid or a cochlear implant, and 71% by three years of age.

- Abstract
Objective: To describe the audiological journey of a group of infants with auditory neuropathy spectrum disorder (ANSD) following the fitting of hearing aids, and to investigate the potential benefits of including cortical auditory-evoked potentials (CAEPs) and a measure of functional auditory behaviour during early audiological management., Design: Results from chart revision of estimated hearing threshold, early behavioural testing, parental observation, and functional auditory behaviour assessments were described, and compared to visual reinforcement audiometry (VRA) thresholds obtained at a mean corrected age of 10 months (SD 3). The relationship with CAEPs and functional performance was examined., Study Sample: The study included 12 infants diagnosed with ANSD and fitted with amplification., Results: The estimated 4FA at a mean corrected age of four months (SD5) was within ± 10 dB of VRA results in 75% of infants when unaided and aided behavioural observation audiometry (BOA), together with unaided and aided parental observations was combined. Infants with a greater proportion of CAEPs present had higher PEACH scores., Conclusions: Delaying amplification until VRA results were available would have led to a significant period of auditory deprivation for infants in this study group. None of the assessments could accurately determine hearing thresholds when used in isolation, however when used in combination clinicians were able to obtain sufficient information to fit hearing aids early, and identify infants requiring closer monitoring.

- Abstract
Objective: The aim of this study was to compare conventional processing with nonlinear frequency compression (NLFC) in hearing aids for young children with bilateral hearing loss., Methods: Sixty-four children aged between 2 and 7 years with bilateral hearing aids were recruited. Evaluations of cortical responses, speech intelligibility rating, consonant perception and functional performance were completed with the children wearing their personal hearing aids with conventional processing. The children were then refitted with new hearing aids with NLFC processing. Following a six-week familiarization period, they were evaluated again while using their hearing aids with NLFC activated., Results: The mean speech intelligibility rating and the number of cortical responses present for /s/were significantly higher when children were using NLFC processing than conventional processing in their hearing aids (p<0.05). Parents judged the children's functional real life performance with the NLFC hearing aids to be similar or better than that with the children's own hearing aids in both quiet and noisy situations. The mean percent consonant score was higher with NLFC processing compared to conventional processing, but the difference did not reach the 5% significance level (p=0.056). An overall figure of merit (FOM) was calculated by averaging the standardized difference scores between processing schemes for all measures. Regression analysis revealed that, on average, greater advantage for NLFC processing was associated with poorer hearing at 4 kHz., Conclusions: Compared to conventional processing, the use of NLFC was, on average, effective in increasing audibility of /s/as measured by cortical evaluations, and higher ratings on speech intelligibility and functional performance in real life by parents. On average, greater benefits from NLFC processing was associated with poorer hearing at 4 kHz., (Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.)

- Abstract
This paper summarizes findings from a population study on outcomes of children with hearing loss in Australia, the Longitudinal Outcomes of Children with Hearing Impairment ( http://www.outcomes.nal.gov.au ) study. Children were evaluated at several intervals using standardized tests, and the relationship between a range of predictors and the outcomes was examined. This paper reports the performance of children with cochlear implants at 5 years of age together with factors predicting word reading ability. Earlier age at cochlear implantation was significantly associated with better word reading ability, after controlling for the effects of language, receptive vocabulary, nonverbal cognitive ability, and device configuration.

- Abstract
Objective: To examine the impact of prescription on predicted speech intelligibility and loudness for children., Design: A between-group comparison of speech intelligibility index (SII) and loudness, based on hearing aids fitted according to NAL-NL1, DSL v4.1, or DSL m[i/o] prescriptions. A within-group comparison of gains prescribed by DSL m[i/o] and NAL-NL2 for children in terms of SII and loudness., Study Sample: Participants were 200 children, who were randomly assigned to first hearing-aid fitting with either NAL-NL1, DSL v4.1, or DSL m[i/o]. Audiometric data and hearing-aid data at 3 years of age were used., Results: On average, SII calculated on the basis of hearing-aid gains were higher for DSL than for NAL-NL1 at low input level, equivalent at medium input level, and higher for NAL-NL1 than DSL at high input level. Greater loudness was associated with DSL than with NAL-NL1, across a range of input levels. Comparing NAL-NL2 and DSL m[i/o] target gains revealed higher SII for the latter at low input level. SII was higher for NAL-NL2 than for DSL m[i/o] at medium- and high-input levels despite greater loudness for gains prescribed by DSL m[i/o] than by NAL-NL2., Conclusion: The choice of prescription has minimal effects on speech intelligibility predictions but marked effects on loudness predictions.

- Abstract
Objective: To determine the influence of choice of prescription and other child-, family- and intervention-related factors on speech, language, and functional performance of hearing-impaired children by three years of age., Design and Study Sample: A randomized controlled design was implemented as part of a population-based, longitudinal study on outcomes of children with hearing impairment (LOCHI) in Australia. Two hundred and eighteen children were randomly assigned to either the NAL or the DSL prescription for first fitting of hearing aids. Their performance outcomes were evaluated., Results: Prescriptive targets were closely matched in children's hearing aids. There were no significant differences in children's language, speech production, or functional performance between prescriptions. Parents' ratings of children's device usage and loudness discomfort were not significantly different between prescription groups. Functional performance within the first year of fitting together with degree of hearing loss, presence of additional disabilities, and maternal education explained 44% of variation in language ability of children by three years of age., Conclusions: There was no significant association between choice of hearing-aid prescription and variance in children's outcomes at three years of age. In contrast, additional disability, maternal educational level, and early functional performance were significant predictive factors of children's outcomes.

- Abstract
Objective: To develop a corpus of sentences in babble noise that is suitable for Mandarin-speaking children. Two experiments were conducted with specific aims of (1) developing sentence material that is grammatically and semantically within the linguistic abilities of children; and (2) improving the efficiency of the test by equalizing the relative intelligibility of individual items in sentences., Design and Study Sample: Sentences were extracted from spoken material of Chinese children aged between 4 and 5 years of age. The sentences were tested for intelligibility in a four-talker babble by 96 adult native speakers of Mandarin. Psychometric functions were generated, and used for adjusting signal-to-noise ratios of individual items by varying the level of the time-locked babble to equate intelligibility of the target speech. These adjusted stimuli were tested for intelligibility using a different group of 64 adult listeners., Results: The signal-to-noise ratio for 50% correct was not different before and after adjustments (- 6.1 dB and - 6.0 dB, respectively). However, there was a significant reduction in standard deviation from 2.3 dB before adjustment to 1.1 dB after adjustment (p < 0.05)., Conclusions: The experiments established a corpus of Mandarin BKB-like sentences with four-talker babble as competing noise, in which the test items' homogeneity was optimized via psychometric evaluation (HOPE).

- Abstract
Unlabelled: The parents' evaluation of aural/oral performance of children (PEACH) scale was developed to assess the effectiveness of amplification for children, based on a systematic use of parents' observations of children's performance in real-world environments., Objective: The purpose of the present study was to adapt the PEACH scale into the Malay language, and to collect normative data on a group of children with normal hearing., Study Sample: The participants were parents of 74 children aged between 3 months and 13 years of age. Parents were requested to observe their children's auditory/oral behavior in everyday life and to record their observations in the PEACH booklet., Results: High internal consistency (Cronbach's alpha = 0.93) and item-total correlation were found (0.52-0.85). Similar to the published norms for English-speaking children, near-perfect scores were achieved by Malaysian children around 40 months of age., Conclusions: The adapted version can be used to evaluate amplification for children in the Malay speaking environment. The normative curve relating age to scores for the Malay PEACH can be used as a reference against which functional aural/oral performance of hearing-impaired Malaysian children can be evaluated.

- Abstract
This paper reports real world preferences of children in a double-blind, cross-over trial comparing NAL-NL1 and DSL v.4.1 prescriptions. Twenty-four children wore digital WDRC hearing aids at each site (Australia, Canada). Multi-memory hearing aids provided the NAL and DSL programs in each of two memories. Diaries were completed during two counterbalanced trials, providing overall preference, situational preference, and preference comments. Ratings were reliable, and situational preferences factored into quiet/low level situations versus noisy/reverberant/high level situations. Children at both sites used DSL v4.1 for hearing low level speech, or when they wanted to hear loudly and clearly. Children used NAL-NL1 when they wished to hear sounds at a lower level, or to reduce background noise. Children expressed strong preferences for having the choice of both programs. Canadian children were more likely to prefer DSL than were the Australian children. Factors such as listening environment and prior listening experience are discussed in interpreting these findings.

- Abstract
This paper reports intelligibility judgments and real-life functional performance of 48 children in a double-blind, cross-over trial comparing the NAL-NL1 and the DSL v.4.1 prescriptions. Intelligibility judgments were obtained by using a paired-comparisons procedure with audiovisual stimuli. Functional performance of children during two eight-week periods, each with hearing aids adjusted to one prescription, was assessed by parents and teachers (PEACH and TEACH) and by children's self reports (SELF). Consistently across reports, performance was significantly better in quiet than in noise. On average, better performance in noise (a higher Noise subscale score) was associated with NAL-NL1 than with DSL v.4.1, both for the PEACH and the SELF. This difference was significant for the SELF in Australia. Intelligibility judgments revealed preferences that were equally split between prescriptions in both countries, on average. In the Australian sample, intelligibility judgments agreed with the questionnaire ratings and with parents' ratings. An increase in preference for NAL was significantly associated with lesser hearing loss. The effect was not significant in the Canadian sample.

- Abstract
This paper reports speech and loudness measures on a group of children in a double-blind cross-over trial comparing the NAL-NL1 and DSL[i/o] prescriptions. Twenty-four children with hearing impairment were fitted with digital WDRC hearing aids at each site (Australia, Canada). Speech recognition was measured for nonsense syllables and for the 50% correct threshold for sentence recognition in noise. Loudness ratings for sentences were made on a 7-point scale. Measures were made at fitting and repeated following 8-week trials. Fitting orders were randomized and counterbalanced. Significant differences in consonant recognition occurred for individual children. On average, scores at the 80 dB SPL presentation level were better with the NAL-NL1 fitting. Loudness ratings differed at baseline but did not differ following home trials. Speech recognition scores revealed a small but significant interaction of prescription with level in quiet but not in noise. Individual children had significant performance differences. Loudness ratings showed significant acclimatization effects for children at both sites.

- Abstract
This paper examined how hearing aids adjusted for comparing NAL-NL1 with DSLv.4.1 prescription formulas matched prescriptive targets. The real-ear-to-coupler differences (RECD) of 48 children (24 in Australia and 24 in Canada) were measured and used to derive coupler gain targets. Verification of gain and output were carried out in an HA2-2cc coupler. Electroacoustic measurements revealed a minimal difference between NAL-NL1 and DSLv.4.1 frequency-response slopes due to practical limitations of the devices, even though the prescribed differences were large (up to 13 dB/octave). The difference in overall gain was generally achieved in the hearing aids, with DSLv.4.1 prescribing higher overall gain than NAL-NL1. The mean RECD at 4 kHz was 5 dB higher for children in Australia than in Canada. As the same RECDs were used in deriving targets for both prescriptions, this is unlikely to affect the results of the comparison. The impact of a gain difference between prescriptions on children's performance and preferences in real life is reported in separate papers.

- Abstract
The relative effectiveness of the NAL-NL1 and the DSL4.1 prescriptions for 48 children with mild to moderately severe hearing loss was studied using a double-blind, four-period, two-treatment cross-over design in Australia and in Canada. Evaluations included speech perception tests, loudness ratings, reports from parents and teachers on functional performance in real life, children's self-reports, paired-comparison judgements of intelligibility, and children's preferences in real-world environments. Electroacoustic measures of hearing aids revealed that gain differences dominated the comparison. Across trials and measures, individual Australian children consistently preferred either the NAL-NL1 or the DSL v.4.1 prescription. An overall figure of merit (FOM), calculated by averaging the standardized difference scores between prescriptions for all measures, revealed that the strongest prescription-related differences were found in Australia. On average, an advantage and preference for the NAL-NL1 prescription was associated with lesser degrees of hearing loss. This research provides evidence on the effectiveness of the NAL-NL1 and DSL v.4.1 prescriptions, and highlights the need for evaluating and fine-tuning amplification to meet the diverse needs of individual children in real life.

- Abstract
This study examined the effect of variations in hearing-aid frequency response on real-life functional performance of children with severe to profound hearing loss. A cross-over design was used in a double-blind comparison of the NAL prescription with alternatives that produced either a BOOST or a CUT (6 dB/octave from 0.5 to 2 kHz), relative to the NAL response. The functional performance of 30 children (aged 7 months to 16 years) when wearing hearing aids adjusted to each response over two to four weeks was assessed by using parents' and teachers' observations (PEACH and TEACH scales). Intelligibility judgments and self-reports were also obtained from school-aged children. Results indicated that on average, variations in frequency response resulted in differences in functional performance in real life. There were significant correlations between PEACH and TEACH, and also between children's intelligibility judgments and subjective reports from children and their parents and teachers. The findings support the use of the NAL response for initial fitting, and the evaluation of children's amplification needs by a systematic use of parents' and teachers' observations.

- Abstract
The Parent's Evaluation of Aural/Oral Performance of Children (PEACH) was developed to evaluate the effectiveness of amplification for infants and children with hearing impairment by a systematic use of parents' observations. The PEACH was administered to 180 parents (one parent of each of 90 children with normal hearing that ranged in age from 0.25 to 46 months, and 90 children with hearing impairment that ranged in age from 4 months to 19 years). The internal consistency reliability was 0.88, and the test-retest correlation was 0.93. Normative data are presented to enable performance of children with hearing impairment to be related to their normally hearing peers and/or other children with similar degrees of hearing loss. Ninety and ninety-five percent critical differences are presented to facilitate evaluation of differences between scores obtained under different conditions for the same individual. The PEACH can be used with infants as young as one month old and with school-aged children who have hearing loss ranging from mild to profound degree.

- Abstract
It is well recognised that normal hearing people use their hearing in both ears to locate sounds and to understand speech in complex listening conditions. Whereas it is standard practice to provide two hearing aids to children with bilateral hearing loss, the situation with cochlear implantation is less certain. Questions remain as to what binaural aided functioning is possible for children who use a hearing aid and a cochlear implant in opposite ears (bimodal hearing). The first part of this paper draws on research at the National Acoustic Laboratories to show that children who used bimodal hearing devices obtained binaural advantages in localization. They could also take advantage of head shadow and binaural redundancy for speech intelligibility. The second part presents data showing that some hearing-impaired children may have binaural processing deficits even when bilateral stimulation is provided. Additional strategies may be necessary to develop or enable the use of binaural cues by these children.

- Abstract
Aim: The aim of this paper was to summarize the binaural advantages for sentence perception in noise and sound localization obtained by children and adults who wore a cochlear implant (CI) and a hearing aid in opposite ears (bimodal hearing devices)., Patients and Methods: We evaluated the speech perception and sound localization ability of 29 children and 21 adults who received a Nucleus CI system in one ear and wore a hearing aid in the other ear. All subjects used hearing aids that were adjusted systematically to complement their CIs. Performance with a CI and a hearing aid was compared with that with a CI alone., Results: On average, both children and adults derived binaural advantages relating to binaural redundancy and head shadow for sentence perception in noise. Neither the degree of hearing loss nor the duration of use of bimodal hearing devices was significantly related to the amount of binaural speech benefits. Both groups also located sounds better with CI and a hearing aid than with CI alone., Conclusions: The evidence supports the implementation of binaural/bimodal fittings as the standard management of children and adults who receive a unilateral CI and who have residual hearing in the nonimplanted ear., (Copyright (c) 2006 S.
