Normal-hearing (NH) listeners can use level differences to segregate pairs of vocoded sentences that are presented interleaved frequency channels; performance is better at both positive and negative target-to-masker ratios (TMRs) compared a TMR 0 dB (Ihlefeld Shinn-Cunningham, 2008). The present study investigated whether unilateral cochlear-implant (CI) users could also alone two sentences. Due the greatly reduced resolution increased thresholds CI users, were in time sequentially. Boston University (Kidd et al., 2008) corpus was used construct interleaved, five-word sentences, consisting name, verb, number, adjective, object. presentation order words alternated randomly for each word type. Each sentence began with same required select last three target sentence. ranged from -12 12 dB. A monaural vocoder showed task possible younger older NH listeners, increasing as difference increased. results user will be presented, effects dynamic-range compression on their discussed.
