Low-Frequency Phase Sensitivity in the Auditory System of a Dolphin

Abstract

It has been shown that a human listener can discriminate click-pairs of different order of the two clicks of unequal amplitude. Ronken (1970) utilized the fact that the power spectrum of a transient is unaffected by reversal of the time scale for producing different stimuli with identical energy spectra. Listeners discriminated such “mirror-image” signals with spectra that differ only in phase at interpulse intervals greater than 1 to 2 ms.
