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.

Abstract Background Although hearing impairment (HI) is linked to poorer physical functioning, the longitudinal associations between HI and higher-level functional measures are unclear. Methods Data is from the Baltimore Longitudinal Study of Aging (2012–2019). Using pure-tone audiometry, we categorized hearing into normal, mild, and moderate or greater HI. Physical function was assessed with the expanded Short Physical Performance Battery (eSPPB) and walking endurance with time to walk 400m. Multivariable and mixed-effects linear models tested the hypotheses that participants with HI, at baseline, have poorer physical performance and walking endurance, and faster decline over time (up to six measurements). In a subset (n=526), we further adjusted for vestibular function. Among participants with HI, we evaluated the differences in eSPPB scores and walking endurance between hearing aid users and nonusers. Results Of 831 participants 26% had mild, and 17% moderate or greater HI. Adjusting for demographics and medical history, moderate or greater impairment vs. normal hearing, was associated with poorer function (0.17 [95% CI: 0.09, 0.26] lower eSPPB score, and 13.3 [95% CI: 3.31, 23.4] seconds slower 400m time) and faster decline in these parameters over 6 years. Adjustment for vestibular function did not attenuate these associations. Hearing aid users walked 400m 24 seconds faster than nonusers (p=0.001). Conclusion Moderate or greater HI is associated with poorer initial and greater decline in higher-level physical performance. The observation that hearing aid users had better walking endurance suggests that screening for and treatment of HI may delay or slow progression of hearing-related functional decline.

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.
