A psychoacoustical study on time resolution of brief intensity changes in dichotic hearing.

Psychoacoustical methods were used to study the phenomena involved in the detected of brief intensity changes within a noise burst. In subjects with normal hearing time intervals between 5 and 100 ms are noticed for the detection depending on the amount of intensity change. The value for a just noticeable difference varies with age and in pathological states. Possible peripheral and central processes of this sort of time resolution ability of the hearing organ are outlined.
