Age-related hearing difficulties. I. Hearing impairment, disability, and handicap--a controlled study

Abstract

The study compares the audiological profile of a group of first-time applicants for hearing aids, a group of re-applicants and a group of non-complainers, aged 70-75 years (n = 71). In spite of overlap in range, a significant difference in thresholds and discrimination was found. The lip-reading capacity was well preserved in the elderly, but showed a significant correlation to the general health condition. The audiological benefit of hearing-aids did not increase with early fitting. General satisfaction with life was independent of satisfaction with hearing; two thirds of the patients were satisfied with their aids and used them regularly. The rest were dissatisfied and used them less than once a week. The aids were most systematically used to watch TV. Pure-tone average and handicap scaling were compared as guidelines for hearing-aid fitting. The most powerful tool to identify those in need of hearing-aids was handicap scaling based on interviews concerning self-assessed hearing difficulties.
