Models of Cetacean Signal Processing
There are several reasons for studying signal processing in dolphins in addition to the pure delight in understanding this mechanism. The most immediate benefit is in being able to predict and understand the results of echolocation tasks assigned to the animal. This is especially important in psychophysical experiments where one wishes to know if a threshold is the result of the behavior of the animal or is actually determined by the stimuli and the ability of the animals’ receiver to detect it. Another reason for studying signal processing is to discover what principals could be used by man in such areas as aids to the blind, sonar, geophysical exploration, etc. Finally, on a metaphysical level, knowledge of how the dolphin processes echoes helps to understand how the animal perceives his environment.
