Abstract

The age differences in gap detection performance between two complex tones in young and old adults is discussed. In a gap detection task, the listener is asked to detect a period of silence between two sounds, the leading and lagging marker. The spectral content of the two markers does not overlap but detect a gap between different auditory channel. The results show that gap detection threshold are only elevated when the two markers do not share a common frequencies and have identifiably different fundamental frequencies.
