Monaural envelope correlation perception is the ability to discriminate between stimuli composed of two or more bands of noise based on envelope correlation. Sensitivity decreases as stimulus bandwidth is reduced below 100Hz. The present study manipulated stimulus bandwidth (25-100Hz) and duration (25-800ms) to evaluate whether performance of highly trained listeners is limited by the number of inherent modulation periods in each presentation. Stimuli were two bands of noise, separated by a 500-Hz gap centered on 2250Hz. Performance improved reliably with increasing numbers of envelope modulation periods, although there were substantial individual differences.
