Effects of stimulus duration on amplitude modulation processing with cochlear implants.

Xin Luo1, John J Galvin, Qian-Jie Fu.   

Abstract

This study investigated temporal integration processes underlying cochlear implant (CI) users' amplitude modulation processing. Thresholds for modulation detection (AMDTs) and modulation frequency discrimination (AMFDTs) were measured for 50-, 100-, and 200-Hz modulation frequencies with stimulus durations from 50 to 400 ms in eight adult CI users. The results showed significant interactions between modulation frequency and stimulus duration for AMDTs and AMFDTs. The data suggest that temporal integration limits CI users' sensitivity to low temporal pitch over short durations, and that temporal integration over longer durations may not enhance CI users' sensitivity to high temporal pitch.
