Recovery characteristics of the acoustic reflex

J Am Aud Soc. 1979 Mar-Apr;4(5):184-9.

Abstract

Acoustic-reflex recovery time was measured as a function of activator intensity level and duration for broad-band noise and a 500-Hz tone in 10 normal-hearing subjects. The activating signals were presented at 5 and 10 dB above individual acoustic reflex thresholds for durations ranging from 0.25 to 100 sec. Reflex-recovery times were similar across both activators and across activator intensity levels. Recovery time was relatively constant for activators of 2 sec or less and increased for longer activator durations. Portions of the results from temporary threshold shift experiments are explained on the basis of acoustic reflex recovery characteristics.
