Abstract

The effects of steady-state acoustic stimulation on resistance of fatigue, as shown by reduction of swimming time, was studied on three sublines of mice, one of which is genetically deaf. High frequency (500-10000 Hz) reduce swimming time from 25% to 50% in mice with normal hearing at a 60-80-dB threshold, but have no effect on deaf mice. Low frequencies and infrasounds (6-50 Hz) reduce swimming time in all mice similarly, even deaf animals, but the threshold is higher (160-115 dB). The use of genetically deaf animals therefore permits elimination of the auditory component; differentiation of the effects of air-borne from those of mechanical vibrations are thus possible.

摘要

通过游泳时间的减少来体现的稳态声刺激对疲劳抵抗力的影响,在三个小鼠亚系上进行了研究,其中一个亚系是遗传性耳聋的。高频(500 - 10000赫兹)使听力正常的小鼠在60 - 80分贝阈值下的游泳时间减少25%至50%,但对耳聋小鼠没有影响。低频和次声(6 - 50赫兹)使所有小鼠,包括耳聋动物的游泳时间类似地减少,但阈值更高(160 - 115分贝)。因此,使用遗传性耳聋动物可以消除听觉成分;从而有可能区分空气传播的影响和机械振动的影响。
