Abstract:

The effectiveness was determined of clicks or narrow band noise NBN acoustic reflex AR stimuli in reducing the temporary threshold shifts TTS of subjects S exposed to continuous noise. Click and NBN reflex arousal stimuli significantly reduced the TTSs of Ss exposed to continuous noise. The click and NBN stimuli did not significantly differ one from the other, however.
