短纯音诱发声动反射的观测

Observation on the sonomotor reflex evoked by tone brust

声动反射是中潜伏期电位中主要的肌性反射，本文对30名听力正常的青年，用0．5KHz、1kHz、2KHz、4KHz短纯音诱发声动反射，观察并测量各波的潜伏期及反应阈。结果提示：此反射的检测，可作为估计听力的一种简便的方法。

Sonomotor reflex is a main muscle reflex of middle lantency potential.By using 0. 5, 1, 2, 4kHz tone brust to evoke sonomotor reflex, 30 young subjects with normal hearing were observed and lantencis of waves and threshold of reaction were measured. The results show the sonomotor reflex is a simple method to test the hearing ability.
