Abstract

OBJECTIVE: The aim was to investigate whether frequency compression (FC) hearing aids provide additional benefit to that conferred by conventional amplification. DESIGN: Participants wore the same hearing aid with FC enabled and disabled for six weeks (ABA design) in each condition. Speech recognition tests (in both quiet and in noise) were administered alongside two questionnaires. Performance was compared across the two signal processing conditions and at different time points. STUDY SAMPLE: Twelve experienced hearing-aid users (aged 65-84 years old) with moderate-to-severe high-frequency hearing loss participated in the study. RESULTS: FC resulted in statistically significantly higher mean scores in all of the administered speech tests. Improvements over time were limited to high frequency phoneme perception. No effect of FC on self-report outcomes was observed. CONCLUSIONS: FC may lead to significant improvements in speech perception outcomes in both quiet and noise for many individuals. No participant was significantly disadvantaged by the use of FC.
