Summary
The purpose of this study is to investigate the functional benefits of frequency compression vs no frequency compression or fitted to hearing loss in severe-profound hearing impaired adults with high frequency hearing losses. Thus, assessing whether hearing aids for this patient population can be adapted to improve speech perception.
Detailed description
Frequency compression is a feature available on some digital hearing aids, which is aimed at increasing the audibility of high frequency sounds. It works by taking sounds above a fixed start frequency and compresses it into lower frequencies where residual hearing is better.
