Summary

The purpose of this study is to determine the effects of age-related cognitive changes on hearing aid benefit based on hearing aid compression time constants.

The hypothesis is that people with poor working memory skills will benefit from slow time constants in hearing aid compression while those with good working memory skills will be able to benefit from more sophisticated compression algorithms with rapid time constants.
