Abstract
Back ground : We evaluated the fit of adjusting hearing aids to ears using the acoustic phenomena.
Method : We used acoustic phenomena to adjust hearing aids, then modified speech audiometry with speaker method suitable to older patients, and measured the discrimination between uncorrected ears and ears with hearing aids.
Results : Discrimination reflected the insertion gain in hearing aids and was represented as a discrimination score. This showed the effect of hearing aid insertion gain.
Conclusion : Our proposed method of fit related to speech audiometry can measure ears with hearing aids simultaneously.
