Invariability of auditory perception with respect to frequency--time signal transformations in the dolphin Tursiops truncatus.
The characteristic of hearing in the dolphin Tursiops truncatus were investigated by the method of motor-feeding conditioned reflexes under conditions of frequency--time signal indeterminancy with background noise. It was shown that the effectiveness of auditory detection of tone--pulse signals is invariant with respect to Doppler and shift signal transformations, while the number of waves is a characteristic parameter of the auditory system.
