Abstract
The aim of this study was to predict the effects of automatic gain control (AGC) on the speech intelligibility of cochlear implant recipients in noise. Two simple signal metrics were calculated: the proportion of clipping, and the output signal-to-noise ratio (SNR). Psychometric functions were fitted to the percent correct scores averaged over five cochlear implant recipients for three different AGC conditions, at two different input SNRs, for a range of presentation levels. The output SNR was a good predictor of the recipients' mean scores.
