Valid Acoustic Models of Cochlear Implants: One Size Does Not Fit All.

ABSTRACT:

Hypothesis

This study tests the hypothesis that it is possible to find tone or noise vocoders that sound similar and result in similar speech perception scores to a cochlear implant (CI). This would validate the use of such vocoders as acoustic models of CIs. We further hypothesize that those valid acoustic models will require a personalized amount of frequency mismatch between input filters and output tones or noise bands.

Background

Noise or tone vocoders have been used as acoustic models of CIs in hundreds of publications but have never been convincingly validated.

Methods

Acoustic models were evaluated by single-sided deaf CI users who compared what they heard with the CI in one ear to what they heard with the acoustic model in the other ear. We evaluated frequenc
