Adaptation of Nonlinear-Amplified Hearing Aid

Comparing the effectiveness of nonlinear amplified hearing aid, S. S. B. peak clipped hearing aid and of linear amplified hearing aid in the perceptive deaf patients the following conclusions were obtained:1. Nonlinear amplified hearing aid was more effective than the linear amplified hearing aid. Majority of the patients preferred nonlinear amplified hearing aid because it had no impulsive tone. But confusion was not reduced.2. The patients agreed that the S. S. B peak clipped hearing aid was more intelligible than the linear amplified hearing aid. The higher discrimination score was obtained by the S. S. B clipped hearing aid, and confusion of consonants (/k/, /t/, /h/, /s/, ) was lowered.
