Abstract

The aim of this study was to examine the effects of four acoustic parameters on the difficulty of extracting a simple 4- note melody from a background of distracter notes. Melody extraction difficulty ratings were recorded while four acoustic parameters of the distracter notes were varied separately: fundamental frequency (FO), intensity, temporal envelope and spectral envelope. The average difficulty ratings for listeners with cochlear implant (CI) users (N=12) were compared with two other groups with normal hearing: with musical training (N=18) and without musical train- ing (N=19). Results show significantly lower results (p<0.05) for the CI group compared to the musician group for the FO..
