Abstract

For cochlear implant users, temporal and place cue are assumed to vary along two orthogonal perceptual dimensions linked to pitch height and timbre. Here, the effect of electrode place, pulse rate, and amplitude modulation frequency on those perceptual dimensions was investigated. Combinations of different electrode places with differing pulse rates or modulation frequencies were presented to the participants while they were asked to rate pitch height and sound quality using multiple verbal attributes. The results indicate that temporal and place cues induce two perceptual dimensions that can be both linked to pitch and timbre.
