Restoration of Spectral Resolution With Hearing-aid Amplification

Completed · Not applicable

Conditions studied: Hearing Loss

In brief

The objective of this study protocol is to determine the efficacy of using aided measures of spectral resolution to set the dynamic range of hearing with hearing-aid amplification. Measures of spectral resolution will be obtained, as will measures of speech recognition.
