Dolphin Whistles as Velocity-Sensitive Sonar/Navigation Signals

Part of the NATO Advanced Study Institutes Series book series (volume 28)


Certain dolphin whistles display a hyperbolic increase in frequency as a function of time, followed by a hyperbolic decrease. These whistles nearly always contain one or more harmonics. The signals were classified as distress calls by Lilly (1963), but they are also used under many other circumstances.
