本文采用文献[1]、[2]所采用的训练方法,对一头人工饲养的白鳍豚的听觉灵敏度进行了测量,得到了频率范围为1kHz～200kHz的听阈曲线。实验表明,白鳍豚最敏感的频率范围为16kHz～48kHz,这一范围的阈值为-38～-44dB,其听力频率上限超过200kHz,下限低于1kHz。文中还对实验中白鳍豚的一些行为进行了讨论。 In this paper, the auditory sensitivity of a captive dolphin cultured on the basis of the training methods adopted in [1] and [2] was measured, and the threshold curve of hearing frequency in the frequency range of 1kHz ~ 200kHz was obtained. Experiments show that the most sensitive white dolphin frequency range of 16kHz ~ 48kHz, the threshold range of -38 ~ -44dB, the upper limit of hearing frequency more than 200kHz, the lower limit of less than 1kHz. The paper also discusses some of the behavior of the dolphin in the experiment.
