Localization of the Acoustic Window at the Dolphin’s Head
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).
