声音在水生哺乳动物，特别是海豚中传递到耳朵的机制仍然不清楚。有人认为声音直接通过头部组织到达内耳，或者声音传播涉及中耳和闭合的听道（Fraser和Purves，1959; Fleischer，1978）。这一假设得到了计算的支持，计算表明，闭合的听道可以作为声音传输到中耳的有效声学Transformer（Lipatov，1978）。
The mechanism of sound transmission to the ear in aquatic mammals, particularly in dolphins, remains obscure. It has been suggested that sound reaches the inner ear directly via head tissues, or sound transmission involves the middle ear and the closed auditory meatus (Fraser and Purves, 1959; Fleischer, 1978). This assumption was supported by calculations indicating that the closed auditory meatus can serve as an effective acoustic transformer for the sounds to be transmitted to the middle ear (Lipatov, 1978).
