This study examined spatial release from masking (SRM) when a target talker was masked
by competing talkers or by other types of sounds. The focus was on the role of interaural time
differences (ITDs) and time-varying interaural level differences (ILDs) under conditions
varying in the strength of informational masking (IM). In the first experiment, a target talker
was masked by two other talkers that were either colocated with the target or were
symmetrically spatially separated from the target with the stimuli presented through …
