抄録
It is the purpose of this experiment to observe recovery of abnormal auditory adaptation by means of Bekesy fixed frequency audiometry and reverse TTD test. After the tested ear showed maximum elevation of auditory threshold in usual TTD tra-cing by nsing a continuous pure tone, the recovery process just from the highly adapted state of the ear was traced by these two methods.<br>Test signals used were the continuous, the amplitude-modulated, and the interrupted pure tones. The results were as follows :<br>1) Bekesy tracing for a continuous pure tone showed no recovery of auditory threshold from the temporary hearing loss in TTD test and smal-ler amplitude than the nonadapted state of the test-ear, whereas that for an interrupted pure tone showed complete recovery from the hearing loss and normal amplitude similar to the nonadapted state.<br>2) As the ampitude modulation of the test tones was increased, recovery curves of Bekesy and reverse TTD tracings were changed in thre-sholds and amplitudes from those of the more adapted state of the test-ear for a continuous tone to those of the less adapted state for an interru-pted tones
