Questionnaire studies were performed to investigate the efficacy of the use of hearing aids 100 questionnaires were collected out of 99 subjects in the study. The summary of the results was as follows.
1) The younger subjects were more satisfied with the use of a hearing aid than the older.
2) The subjects wearing a hearing aid for a long time are more satisfied with it.
3) The satisfactory order in the use of a hearing aid was behind the ear type (BTE)>in the ear type (ITE)>compeletely in the canal type (CIC); the larger one was more satisfactory.
4) K-amp types were more preferred in a calm place, on the other hand, digital types in background noise. In terms of music, linear and Kamp types were preferred.
5) The range of frequency threshold of a hearing aid worn by subjects, if possible, was measured to evaluate individual frequency gain among BTE, ITE, and CIC. No significant difference was found among them except the worse gain in the lower frequency of BTE.
6) The results of questionnaires suggest a direct correlation between the hearing aid gain of the subjects in the pure tone average and their hearing ability within a short distance.
