title: The role of interaural differences on speech intelligibility in complex multi-talker environments.
abstract: Interaural differences in time (ITDs) and interaural differences in level (ILDs) contribute to a listener's ability to achieve spatial release from masking (SRM), and help to improve speech intelligibility in noisy environments. In this study, the extent to which ITDs and ILDs contribute to SRM and the relationships with aging and hearing loss were examined. SRM was greatest when stimuli were presented with consistent ITD and ILD, relative to ITD or ILD alone, all of which produced greater SRM than when ITD and ILD cues were in conflict with each other. This pattern was independent of age and hearing loss.
