Abstract:
:The literature suggests that directional microphone hearing aids (DMHAs) are a viable means for improving the signal-to-noise ratio (SNR) for hearing-impaired listeners. The amount of directional advantage they provide, however, remains relatively unclear because of variability observed among individual studies. The present investigation was undertaken in an attempt to establish the degree of advantage provided by DMHAs. Data were synthesized from 72 and 74 experiments, respectively, on omnidirectional hearing aids and DMHAs representing both favorable and unfavorable outcomes. Using a meta-analytic approach, 138 weighted averages were derived for a variety of comparable independent and dependent variables. Comparisons were made for hearing-impaired and normal-hearing listeners. Findings are discussed with regard to their clinical and research implications.
