Recognition Testing

This report is the first of two detailing a longitudinal follow-up of hearing aid users. Sixty-five subjects were followed for 12 months post-hearing aid fitting. Objective tests included insertion gain, the Speech Perception in Noise (SPIN) test (Kalikow, Stevens & Elliott, 1977; Bilger, Neutzel, Rabinowitz, & Rzeczkowski, 1984) and the Nonsense Syllable Test (NST) (Levitt & Resnick, 1978) presented in quiet and noise backgrounds. Initially each subject’s hearing aid was fit to the revised National Acoustic Laboratories prescriptive formula (NAL-R) (Byrne & Dillon, 1986) using insertion gain measures. Use gain, measured at 6 and 12 months post-fitting, indicated that subjects generally used those prescribed values, except for subjects in the steeply sloping configuration subgroup. The NST and SPIN tests were administered at the fitting and at 1, 3, 6, and 12 months post-fitting. No change in performance, or training effect, was found for the group or for factors of experience, degree of hearing loss, configuration of hearing loss, use time, or circuit type. Failure to demonstrate a training effect may be attributed, in part, to the fact that initial speech recognition testing was done with the hearing aid volume set at the prescribed values. None of the circuits used showed performance superiority, except when comparing scores for the NST obtained in a quiet background to those obtained in a background of speech-weighted noise. In that comparison, the users of adaptive filter circuits exhibited less deterioration of performance in a noise background.

Counseling Adolescents

Abstract Audiologists have a responsibility to counsel patients with auditory concerns on methods to manage the inherent challenges associated with hearing loss at every point in the process: evaluation, hearing aid fitting, and follow-up visits. Adolescents with hearing loss struggle with the typical developmental challenges along with communicative challenges that can erode one's self-esteem and self-worth. The feeling of “not being connected” to peers can result in feelings of isolation and depression. This article advocates the use of a Narrative Therapy approach to counseling adolescents with hearing loss. Adolescents with hearing loss often have problem-saturated narratives regarding various components of their daily life, friendships, amplification, academics, etc. Audiologists can work with adolescents with hearing loss to deconstruct the problem-saturated narratives and rebuild the narratives into a more empowering message. As the adolescent retells their positive narrative, they are likely to experience increased self-esteem and self-worth.

The present study examined the phenomenon of acclimatization in persons with a severe-to-profound hearing loss. A secondary purpose was to examine the efficacy of a digital nonlinear power hearing aid that has a low compression threshold with expansion for this population. Twenty experienced hearing aid users wore the study hearing aids for three months and their performance with the study hearing aids was evaluated at the initial fitting, one month, and three months after the initial fitting. Performance of their current hearing aids was also evaluated at the initial fitting. Speech recognition testing was conducted at input levels of 50 dB SPL and 65 dB SPL in quiet, and 75 dB SPL in noise at a +10 SNR. Questionnaires were used to measure subjective performance at each evaluation interval. The results showed improvement in speech recognition score at the one-month evaluation over the initial evaluation. No significant improvement was seen at the three-month evaluation from the one-month visit. In addition, subjective and objective performance of the study hearing aids was significantly better than the participants' own hearing aids at all evaluation intervals. These results provided evidence of acclimatization in persons with a severe-to-profound hearing loss and reinforced the precaution that any trial of amplification, especially from linear to nonlinear mode, should consider this phenomenon.

Objective To use data-logging technology to objectively track and identify predictors of hearing aid (HA) usage and aided sound exposure. Study Design Case series with planned data collection. Setting Tertiary academic medical center. Subjects and Methods Individuals with HAs between 2007 and 2016 were included (N = 431; mean, 74.6 years; 95% CI, 73.1-76.0). Data-logging technology intrinsic to new-generation HAs was enabled to track usage and sound exposure. With multivariable linear regression, age, sex, number of audiology visits, duration of audiologic follow-up, pure tone average, and HA side were assessed as predictors of usage (hours/day) and aided sound exposure (dB-hours/day; ie, “dose” of sound per day). Results Mean follow-up was 319 days (95% CI, 277-360). Mean HA usage was 8.4 hours/day (95% CI, 8.0-8.8; N = 431). Mean aided sound exposure was 440 dB-hours/day (95% CI, 385-493; n = 110). HA use (β < 0.001, P = .45) and aided sound exposure (β = −0.006, P = .87) were both stable over time. HA usage was associated only with hearing loss level (pure tone average; β = 0.030, P = .04). Aided sound exposure was associated only with duration of audiologic follow-up (β = 0.100, P = .02). Conclusion While measurement of HA use has traditionally relied on subjective reporting, data logging offers an objective tool to longitudinally track HA use and sound exposure. We demonstrate the feasibility of using this potentially powerful research tool. Usage and sound exposure were stable among patients throughout the study period. Use was greater among subjects with greater hearing loss. Maximizing aided sound exposure might be possible through continued audiology follow-up visits.

Hearing Aid Use

Abstract Background Previous studies have reported associations between hearing impairment (HI) and cognitive impairment, but the evidence is not conclusive while considering concurrent geriatric syndromes. Especially, evidence from previous studies rarely came from Asian studies. This study aimed to evaluate the independent effects of HI and hearing aid use on the incidence of cognitive impairment while considering most geriatric confounders. Methods This population-based, propensity-score matched cohort study used cohort from Waves IV–VII (1999–2011) survey of the Taiwan Longitudinal Study on Aging (TLSA). Cognitive impairment was identified based on Short Portable Mental Status Questionnaire (SPMSQ) scores. The hazard ratio (HR) was calculated using the Cox proportional hazard regression adjusting for age, sex, comorbidities, socioeconomic status, Center for Epidemiologic Studies Depression (CES-D) scores, the instrumental activities of daily living scale, mobility condition and quality of life. In addition, social support and participation were also considered as confounders in the analysis. To assess the robustness of our findings, we conducted a sensitivity analysis designed to access unmeasured confounding factors by calculating E-values. Results After 1:1 propensity-score matching, we included 709 participants in both the HI and non-HI groups with a mean age of 73.4 years and 39.4% of participants were female. The mean follow-up was 8.9 ± 3.9 years. The HI group had a higher incidence of cognitive impairment than the non-HI group (74.5% vs. 69.1%, respectively), with an adjusted HR of 1.16 (95% confidence interval [CI], 1.03–1.32) based on a 12-year follow up. The E-value was 1.45 for the estimate, which provided evidence for this study’s robustness. Although, a subgroup analysis showed that hearing aid use was associated with lower incidences of cognitive impairment (66.3% vs. 75.6%) when compared to non-users in the HI group, the adjusted HR of 0.82 (95% CI, 0.61–1.09) revealed no significant differences. Conclusions HI was an independent risk factor of incident cognitive impairment on top of concurrent geriatric syndromes. Early HI detection may thus be effective for preventing cognitive decline. Further studies are needed to evaluate the effect of hearing aid use on the prevention of cognitive decline.

Children With Hearing Loss

Purpose Hearing loss can have a negative impact on a child's development. Hearing aids, if fitted appropriately, maintained well, and used regularly, can offer benefit to children with hearing loss. Regular reviews of hearing aid users can help to monitor a child's progress and provide timely intervention when problems arise or needs change. This study investigates the follow-up care received by children fitted with hearing aids at a clinic in Malawi. Method A clinical audit was done of the frequency of face-to-face follow-up appointments, following which all pediatric hearing aid users who had not recently received follow-up care were called to invite them for a review, and then a re-audit was conducted. Results Of the 47 children in the audit, 46 had not had a recent face-to-face follow-up appointment. Strenuous efforts were made to call those 46 children to the clinic for review: 20 caregivers agreed to bring their child for review, 10 of whom attended. It was not possible to contact 24 caregivers. Conclusions Reasons for low attendance for review at this service are not known, but may be related to the financial circumstances of the patients' families as well as difficulty in maintaining contact with families. It has not yet been possible to establish a system for routine follow-up care for pediatric hearing aid users at this well-established clinic in a low-income country.

Purpose To screen hearing and evaluate outcomes in community-dwelling older adults. Method Three thousand and twenty-five adults responded to an invitation to be screened by questionnaire, otoscopy, and pure-tone audiometry. Pure-tone average (PTA) >35 dB HL in the worse ear, unilateral hearing loss, or otoscopic findings were the criteria for referral for services. A questionnaire related to compliance with referral recommendations was completed by telephone interview for 160 randomly selected participants after 1–2 years from referral. Results The referral rate for audiologic/hearing aid evaluation was 46%, and referral for cerumen removal/medical evaluation was 17%. Of the people referred for audiologic/hearing aid evaluation, 18% tried a hearing aid; 2 years later, 11% were using a hearing aid. Screening recommendations affected participants' decision to seek help. Study participants stated that the screening was helpful, it should be offered to everybody, and they would participate in future screenings. Conclusion Although adult hearing screening offered timely identification of hearing loss for adults seeking help, follow-up with hearing aid treatment was low.
