The auditory input area of the dolphin head was investigated in an unrestrained animal trained to beach itself and to accept noninvasive electroencephalograph (EEG) electrodes for the recording of the auditory brain-stem response (ABR). The stimulus was a synthetic dolphin click, transmitted from a piezo-electric transducer and coupled to the skin via a small volume of water. The results conform with earlier experiments on acute preparations that show best auditory sensitivity at the middle of the lower jaw. Minimum latency was found at the rear of the lower jaw. A shaded receiver configuration for the dolphin ear is proposed.
在一只经过训练能自行上岸并接受非侵入性脑电图（EEG）电极以记录听觉脑干反应（ABR）的未受束缚的动物身上，对海豚头部的听觉输入区域进行了研究。刺激源是一个合成的海豚滴答声，由压电换能器发出，并通过少量水耦合到皮肤上。结果与早期对急性标本的实验一致，这些实验表明在下颌中部听觉灵敏度最佳。在下颌后部发现了最短潜伏期。提出了一种用于海豚耳朵的带遮蔽的接收器配置。
