Abstract

The auditory system of Cetaceans is characterized by a number of unique features. One important characteristic of the auditory system, used for fine discrimination of sound images, is the frequency selectivity of the auditory channels (filters). In the past years, attempts were made to measure the pass bands of the auditory filters (critical bands) in dolphins. These measurement were carried-out by the tone-tone and noise-tone masking (Johnson, 1968; Moore and Au, 1983). These studies were conducted using behavioral methods with specially trained animals. The complexity and time-consuming task of the behavioral method limits the number of subjects that can be measured, so accessible data are limited.
