Electrophysiological study of interaural sound intensity difference in the dolphin Inia geoffrensis.
A wave observed in the auditory brainstem responses (ABR), sensitive to the side of sound presentation, is described in a dolphin (Inia geoffrensis). Dependence of the wave threshold on location of the sound source showed that the interaural intensity difference was more than 20 dB.
