Prediction of hearing aid users' satisfaction.

This study raised the question of whether certain methods of hearing aid evaluation could predict subjects' satisfaction and willingness to use their aids. For this purpose, we compared two hearing aid evaluation methods on 30 subjects between the ages of 55 and 65 years, all of whom were hearing aid users for some months. Five signal-to-noise ratios were used. The results of this experiment indicated a significant and positive correlation between subject satisfaction and subject willingness to use the hearing aid. Results of multiple regression analyses indicated that both evaluation methods were better predictors of usage than of satisfaction.
