Abstract

Research on the auditory and echolocation performance of Tursiops truncatus since 1980 has proceeded slowly due to limited resources and the expense of conducting basic psychoacoustic research as compared to more general studies concerned with the natural history of the species. Echolocation is essentially a special extension and adaptation of the marine mammal hearing system coupled with an ability to generate sounds. Humans have the ability to judge room size based on reverberation from their own voice and some blind people use self generated sounds to detect reflective objects (Rice, 1966). Echolocation can be thought of as representing a highly refined acoustic ability on a broad acoustic sensory continuum.
