Peripheral versus central processing of a gap between two complex tones in young and old adults

Stephan De La Rosa, Antje Heinrich, A. Schneider Bruce


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.
