Abstract
An interrnpted tone (on-fraction 0.5; tonal duration 2000 msec; 3000 cps, 95 db (SPL)) was applied to induce TTS for 10 normal ears.
The relation between the total duration of the interrupted stimuli and the degree of TTS was studied for both ATP-applied group and non-applied group (Fig. 1).
From these results it was found that ATP was effective to reduce the degree of TTS, and the recovery time from it.
Authors studied also on the intraauralmusle reflex and on the intensity duration threshold.
Considering these results, they concluded that the preventing mechanism of ATP from TTS was due to the process of time constant elamant in perceptional mechanism.
