Practical method for quantifying hearing aid benefit in older adults.

Self-assessment handicap scales are gaining recognition as objective measures of audiologic intervention, including benefit derived from hearing aid use. A short form of the Hearing Handicap Inventory for the Elderly (HHIE-S) comprised of 10 items (5 emotional and 5 social/situational) was administered to 91 new hearing aid users prior to and 3 weeks following hearing aid provision. A significant reduction in perceived emotional and social/situational effects of hearing impairment was observed following this brief interval of hearing aid use. The magnitude of hearing aid benefit was not affected by pure-tone sensitivity or word recognition ability. Further, a 95 percent confidence interval was established for the HHIE-S (9.3 points) in order to determine a true change in self-perceived handicap and pre- and post-hearing aid fitting for a given subject. Our findings support the use of the HHIE-S as an expedient approach for quantifying hearing aid benefit in a busy clinical practice.

Effect of digital filtering of ABR on scorer variability.

The utility of digital filtering for the purpose of improving waveform morphology and improving peak detection was investigated. Unfiltered (i.e., only standard analog filtering) and digitally filtered (i.e., analog plus post hoc digital filtering) ABRs from both young and elderly subjects were independently scored by eight experienced clinicians. Measures of intrascorer and interscorer variability were obtained for the absolute latencies of waves I, III, and V. Results suggest that digital filtering tends to increase the reliability of latency measurements when ABRs are characterized by poor morphology.

Effect of stimulus parameters on auditory brainstem response spectral analysis.

A recent increase of interest in spectral analysis has been prompted by the suggestion that spectral components of the ABR may contribute to differential diagnosis. Knowledge of the effects of stimulus parameters on the spectral content of the ABR is essential. The present study examined the effect of intensity, rate, and polarity on the spectral content of ABRs of 15 normal-hearing subjects. The effects of intensity were significant at all spectral frequencies examined while the effects of rate and polarity were frequency specific. These results indicate that the effects of stimulus parameters must be considered in examining the ABR spectral analysis.

Measurement of hearing aid benefit in the elderly.

Providing amplification is at the heart of most rehabilitation programs for the elderly. Given the importance of quality assurance, methods of quantifying hearing aid fitting success are needed. This study was designed to assess the adequacy of a self-assessment scale at measuring hearing aid benefit following a 3 week interval of hearing aid use. Forty-five new hearing aid users completed the Hearing Handicap Inventory for the Elderly (HHIE) prior to and following 3 weeks of hearing aid use. Results of the study showed a significant reduction in handicap following 3 weeks of hearing aid use, suggesting the feasibility of using the HHIE as an outcome measure for hearing aid success after a brief interval of hearing aid use. Subjects will be followed longitudinally to determine the best time frame in which to administer this scale.
