The role of non-energetic (‘informational’) masking and memory processes on the ability of listeners across the age span to make multiple simultaneous or sequential judgments in various domains (intensity, location, speech); the influences of age and hearing loss on binaural sensitivity, binaural interference, and binaural and monaural temporal integration; amplitude-modulation sensitivity and its role in speech intelligibility and interactions with compression in hearing aids; potential impacts of cognitive impairment on auditory tasks.
