Summary

The purpose of this study is to better understand the sensitivity of listeners to the fast changes in frequency or amplitude of sounds that occur in speech. The investigators are studying ways to manipulate these aspects of sounds in an effort to make speech sounds more clear.

Conditions

  • Hearing Loss, Sensorineural

Interventions

OTHER

Signal processing to improve intelligibility

Signal processing will be used to manipulate frequency and amplitude fluctuations in complex sounds.
