摘要
海洋开发事业中,由于水下工程和通讯联络的需要,水声技术进展很快,在它的带动下,生物声学也迅速发展起来。鱼类发声和听觉的研究,就成为水下生物声学的重要内容之一。
1. Typical microphonic potentials of the acoustic response from the inner ear sacculus of perch, Laleolabrax japonicus, were recorded by using the mono-frequency sound produced by an under water loudspeaker, a device for calling fish, as the stimulus signal. 2. It has been shown by experiment that the ear of perch can detect sounds from 40 to 600 Hz. 3. By taking the 30 microvolt microphonic potential as the basis, a hearing power curve was prepared and it shows there is a noticeable low threshold between 170 and 200 Hz.
