Measurement were made of the cochlear potentials in three specimens of the giant sea turtle, Chelonia mydas, in response to both aerial and mechanical stimulation of the ear. The results show maximum sensitivity in the region of 300 to 400 Hz, with a rather rapid decline in sensitivity for lower and especially for higher tones. The upper limit for the observation of cochlear potentials without injury is 2000 Hz, and a practical limit of usefulness of this ear is probably about 1000 Hz.
对三只绿海龟(蠵龟)标本的耳蜗电位进行了测量,以响应耳部的空气和机械刺激。结果表明,在300至400赫兹范围内灵敏度最高,对于低音尤其是高音,灵敏度下降相当快。在不造成损伤的情况下观察耳蜗电位的上限是2000赫兹,而该耳朵实际有用的极限可能约为1000赫兹。
