For normal-hearing (NH) listeners, masker energy outside the spectral region of a target
signal can improve target detection and identification, a phenomenon referred to as
comodulation masking release (CMR). This study examined whether, for cochlear implant
(CI) listeners and for NH listeners presented with a “noise vocoded” CI simulation, speech
identification in modulated noise is improved by a co-modulated flanking band. In
Experiment 1, NH listeners identified noise-vocoded speech in a background of on-target …
