In a simulation of the "cocktail party" problem, subjects listened to recordings of a target voice, obscured by four background voices from adjacent locations in space. Listening conditions were either dichotic (with interaural directional cues preserved) or diotic (same input to both ears, directional cues removed). Elderly subjects were unable to use… (More)
