Purpose: This study aimed to compare the preferred real-ear insertion gain for Korean (PREIG-K) wearing multi-channel hearing aid with the National Acoustics Laboratories-Non-Linear version 2 (NAL-NL2; National Acoustic Laboratories) gains in order to develop Korean hearing aid fitting formula.Methods: A total of thirty one (62 ears) Korean hearing aid users were included in this study. All subjects wore in-the-canal or custom hearing aids in both ears. Individual hearing aid fitting procedures involved to adjust the gains for 50, 65, and 80 dB sound pressure level of speech across low, high, and wideband frequency bands based on participant’s subjective responses. In addition, only the high frequency bands of 1 kHz or more of the PREIG-K were re-adjusted to be the same as NAL-NL2 gain and then the word recognition scores (WRSs) were compared before and after the adjusting gain. Results: The results showed that the PREIG-K increased up to 1.5 kHz with the maximum amount, then the PREIG-K decreased across the frequencies. For all half octave frequencies, the PREIG-Ks were substantially less than the NAL-NL2. When the PREIG-K of high frequencies were re-adjusted same as the NAL-NL2 gains, the WRSs of the PREIG-K were not significantly different before and after gain adjustment. The slopes up to 1.5 kHz frequencies of the PREIG-K were steeper than the slopes of NAL-NL2 gain, however similar to the slope of manufactures’ fitting formulae.Conclusion: The development of an effective hearing aid fitting formula for improving the communication abilities of hearing-impaired Korean will require further experiments considering the language, physical characteristics, and word recognition used by Koreans.

Large Vestibular Aqueduct

A 23-month-old female was referred for hearing aid fitting after failing newborn hearing screening and being diagnosed with significant hearing loss through subsequent diagnostic testing. Auditory brainstem response (ABR) and behavioral testing revealed a moderate-to-severe bilateral mixed hearing loss. Prior to the hearing aid evaluation, tympanostomy tubes had been placed bilaterally with little or no apparent change in hearing sensitivity. Initial testing during the hearing aid fitting confirmed earlier findings, but abnormal middle ear results were observed, requiring referral for additional otologic management. Following medical clearance, binaural digital programmable hearing aids were fit using Desired Sensation Level parameters. Behavioral testing and probe microphone measures showed significant improvements in audibility. Decrease in hearing sensitivity was observed six months following hearing aid fitting. Radiological studies, ordered due to the mixed component and decreased hearing sensitivity, revealed large vestibular aqueduct syndrome (LVAS). Based on the diagnosis of LVAS, a cochlear implant was placed on the right ear; almost immediate speech-language gains were observed.

Fitting Hearing Aids

Fitting hearing aids to infants with hearing loss can be completed in a systematic and evidence-based manner. This is because there are clinical protocols and technologies available so that pediatric audiologists can fit hearing aids to their patients with hearing loss during the early months of life. Early hearing aid fitting supports speech and language development, however, the way in which the hearing aid is fitted can significantly impact the infant’s progress. A four-stage process for infant hearing aid fitting is offered as a framework with which to execute the essential components of the procedure. Key aspects of the pediatric hearing aid fitting process are described with a focus on elements that may impact an infant’s progress with hearing aids if not implemented.

Parent Experiences

Background: Children born with permanent hearing loss have the opportunity to receive services earlier as a result of newborn hearing screening (NHS). We conducted a survey to address three aspects within the early hearing detection and intervention (EHDI) process: (1) timeliness of service delivery, (2) hearing device access, and (3) hearing aid management. Parent experiences provide valuable information in identifying existing challenges for these components of the EHDI system. Purpose: The aim was to investigate parent experiences as they access and manage hearing aids for their child. Research Design: A cross-sectional, population-based survey was used. Study Sample: Three hundred fifty-two completed surveys from parents of children born between 1977 and 2010 were returned from 45 states in the United States. Data Collection and Analysis: Responses were obtained online and through the mail, and were analyzed using descriptive statistics. Results: Over time, the age of hearing loss identification has decreased to a median of 2 mo, age of first hearing aid fitting has decreased to a median of 5 mo, and the delay between hearing loss identification and hearing aid fitting has remained the same with a median of 2 mo. For children born between 2007 and 2010, the top three challenges parents reported in obtaining hearing aids were (1) paying for hearing aids, (2) accepting the need for hearing aids, and (3) wait time for an appointment. Almost one-half (48%) of the parents reported that they did not receive adequate support from their audiologist in how to check the function of their child's hearing aids. Conclusions: Significant progress has been made over the past two decades in reducing the age of hearing loss identification and hearing aid fitting for children who do not pass the NHS. However, many children continue to experience delays between hearing loss diagnosis and hearing aid fitting that exceed Joint Committee on Infant Hearing recommendations. The experiences parents reported provide valuable information about areas that need further investigation to improve the process for children with hearing loss.

The Impact

Background: Guidelines and protocols for pediatric hearing aid fitting are necessary to meet the goals of Early Hearing Detection and Intervention (EHDI) programs. The American Academy of Audiology published an update to their Pediatric Amplification Guideline in 2013. Ontario's Infant Hearing Program (IHP) offers specific protocols that aim to fulfill recommended guidelines. It has recently been updated to align with the American Academy of Audiology Guideline and other evidence. Purpose: A summary of the updates to the Ontario IHP’s Amplification Protocol is described. In addition, data illustrating hearing-related outcomes of the program are offered. Research Design: The updated Ontario protocol is based on evidence, wherever possible. Where research is not yet available, clinical decision support has been described in a systematic way. Outcomes of the Ontario IHP were obtained through a longitudinal clinical observation study. Study Sample: One hundred and fifteen children with hearing loss, who wore hearing aids, were included in the outcome analyses (mean = 28.6 mo; range = 1.3–115.3 mo). Hearing losses ranged from mild to profound, unilateral or bilateral sensorineural (pure-tone average = 52.3 dB HL). They were recruited from four IHP clinics within Ontario. Children with complexities in addition to hearing loss were included. Intervention: The children were fitted with hearing aids following Ontario's Amplification Protocol. Data Collection and Analyses: During routine clinical appointments, IHP Audiologists administered questionnaires to the parents of their pediatric patients using a systematic outcome measurement protocol (University of Western Ontario Pediatric Audiological Monitoring Protocol). Hearing aid fitting details (e.g., speech intelligibility index) were also gathered to describe the quality of the hearing aid fittings in relation to the functional outcomes. Regression analyses were conducted to characterize scores on the questionnaires and the impact of important variables. Children with complexities were analyzed separately from those who were typically developing. Results: Important updates to Ontario's Amplification Protocol offer new details about candidacy considerations as well as technical updates. Outcomes from the IHP reveal protocol elements can be executed clinically and when they are, typically developing children who wear hearing aids are meeting auditory development and performance milestones. Conclusions: Updates to Ontario's Amplification Protocol are necessary to support the evolution of EHDI programs and the evidence which sustains them. With advances in technology and additional research, pediatric hearing aid fitting will continue to progress and support systematic measurement of outcomes for children who wear hearing aids. The application of state-of-the-art hearing aid fitting practices to the pediatric population within EHDI programs supports good outcomes for infants and children with hearing loss.

Background: The International Outcome Inventory for Hearing Aids (IOI-HA) is a seven-item hearing-specific questionnaire. It was developed with the purpose of evaluating the efficacy of hearing aid rehabilitation. Few psychometric properties have been presented for a Swedish translation of the IOI-HA. Furthermore, previous studies have examined the IOI-HA in mainly sensorineural hearing losses, and we do not know how the type of hearing loss affects the outcome. Purpose: To evaluate the hearing aid fitting outcome measured in a clinical setting using a Swedish translation of the International Outcome Inventory for Hearing Aids (IOI-HA), to determine the psychometric properties of the translation, and to examine how a number of demographic variables such as type of hearing loss affect the outcome. Research Design: A descriptive and correlational study in a retrospective sample. Study Sample: Two hundred and twenty-four (107 females and 117 males; ages 27–94 yr with an average of 66.1 yr) first-time hearing aid users. Intervention: Mostly digital hearing aids (97.8%) were fitted monaurally (60%) or binaurally (40%) between 2007 and 2009. Data Collection and Analysis: The subjects were mailed the IOI-HA questionnaire six months after their final appointment, and the completed questionnaire was returned by mail to the clinic. The psychometric properties were evaluated and compared to previous studies using the IOI-HA. The associations between the outcome scores and a number of demographic variables (age, gender, degree of hearing loss, type of hearing loss, number of hearing aids, and type of hearing aids) were examined. Based on the pure tone audiograms, the subjects were divided into three groups; those with conductive hearing losses, sensorineural hearing losses, and mixed hearing losses. For these groups, the differences in outcome measured as IOI-HA were examined. Results: The psychometric properties of the present translation of the IOI-HA showed resemblance in many aspects to previous reports. Furthermore, the type of hearing loss seems to affect the IOI-HA outcome. Hearing loss increases with increasing age, and hearing aid use increases with increasing degree of hearing loss. Subjects with sensorineural hearing losses show significantly poorer scores on items concerning introspective aspects of the outcome in comparison to subjects with mixed hearing losses and subjects with conductive hearing losses. Monaurally fitted subjects tend to report lower scores on average, but monaural or binaural hearing aid fitting do not significantly affect the subjective outcome. Conclusions: The psychometric properties of the present Swedish translation of the IOI-HA show resemblance in many aspects to previous reports, but the differences observed could be due to differences in the study populations. Overall, the demographic variables examined could not be used as predictors for the hearing aid fitting outcome, and more reliable predictors need to be identified.

Hearing Aid Fitting

People with hearing loss experience fatigue, and it is unknown whether this is alleviated by treatment with hearing aids. The objective of this study was to address this issue, and to investigate the possible concomitant effect of hearing-aid fitting on activity levels. An intervention group (n=53) who were due to be fitted with their first ever hearing aid(s) and a control group (n=53) who had hearing loss but no change in hearing aid status completed a battery of self-report outcome measures four times: once before fitting, and at two weeks, three months and six months post fitting. Self-report outcome measures at each assessment captured fatigue, listening effort, hearing handicap, auditory lifestyle, social participation restrictions and work, social and physical activity levels. Hearing-aid fitting led to a significant reduction in listening-related fatigue, but not general fatigue, in the intervention group compared to the control group. Additionally, social activity level increased and social participation restriction decreased significantly after hearing aid fitting in the intervention group compared to the control group. No significant interaction was found between working status and change in listening-related fatigue score. This study is the first to make longitudinal measurement of fatigue before and after first-ever hearing aid fitting and to identify an increase in social activity level after hearing aid fitting. These findings have important implications for future research and the clinical practice of hearing aid fitting.

Age Range

Background: In spite of early identification and intervention efforts achieved by Early Hearing Detection and Intervention (EHDI) programs, many infants with hearing loss experience delays in early vocabulary development in comparison to peers with normal hearing (Mayne, Yoshinaga-Itano, Sedey, 2000a; Mayne, Yoshinaga-Itano, Sedey, Carey, 2000b; Moeller et al, 2007a, 2007b). One of the several factors that may contribute to individual differences in outcomes is inconsistent hearing aid use in this age group. This may be associated with the physical fit when using traditional behind-the-ear (BTE) hearing aids, since they are relatively large in comparison with the small and soft ear of an infant. Receiver-in-the-ear (RITE) hearing aids may be advantageous for use in pediatric fittings, since they are very tiny and lightweight and therefore sit comfortably on a small soft ear. Purpose: To evaluate the use of a RITE hearing aid with an instant ear-tip especially developed for infants in terms of physical fit, stability, safety, and security of the device, as well as the use of retention tools (remedies for keeping the hearing aid securely on the ear) with this age group. Research Design: A longitudinal study with hearing impaired infants fitted with RITE hearing aids was performed. Study Sample: Eighteen infants with mild to moderate/severe hearing loss participated in the study. The age range was 2–36 mo. Sixteen infants had worn hearing aids prior to their participation in the study. Intervention: Each hearing impaired infant was fitted with the RITE hearing aid and an instant ear-tip, the size of which was chosen by the audiologist. The infants used the device for a period of 2–5 mo. Data Collection and Analysis: Audiologists and parents completed questionnaires at every visit (5–7 visits in total). Responses were obtained using a category rating scale (Stevens, 1975) from 0 to 10. The data were analyzed using descriptive statistics and nonparametric statistics. Results: Sixteen of the 18 children completed the study. At the end of the study, 11 of the 16 children were using the instant ear-tip, whereas five children were fitted with the receiver mounted in a custom earmold. The audiologists rated the RITE solution to provide a safe, stable, and secure fit. The general trend was that ratings improved over time. At the final follow-up session, all median ratings were between 8 and 10. Conclusions: Based on the positive results obtained in the study, the use of an appropriately designed RITE hearing aid is recommended for infants.

Children With Hearing Loss

Purpose Because of uncertainty about the level of hearing where hearing aids should be provided to children, the goal of the current study was to develop audibility-based hearing aid candidacy criteria based on the relationship between unaided hearing and language outcomes in a group of children with hearing loss who did not wear hearing aids. Method Unaided hearing and language outcomes were examined for 52 children with mild-to-severe hearing losses. A group of 52 children with typical hearing matched for age, nonverbal intelligence, and socioeconomic status was included as a comparison group representing the range of optimal language outcomes. Two audibility-based criteria were considered: (a) the level of unaided hearing where unaided children with hearing loss fell below the median for children with typical hearing and (b) the level of unaided hearing where the slope of language outcomes changed significantly based on an iterative, piecewise regression modeling approach. Results The level of unaided audibility for children with hearing loss that was associated with differences in language development from children with typical hearing or based on the modeling approach varied across outcomes and criteria but converged at an unaided speech intelligibility index of 80. Conclusions Children with hearing loss who have unaided speech intelligibility index values less than 80 may be at risk for delays in language development without hearing aids. The unaided speech intelligibility index potentially could be used as a clinical criterion for hearing aid fitting candidacy for children with hearing loss.
