[The invariance of auditory perception with regard to frequency-temporal transformations of the signal in Tursiops truncatus dolphins].
In experiments on the porpose T. truncatus, using motor-feeding conditioned reflex technique, studies have been made on hearing under the conditions of frequency-temporal indetermination of the signal presented at noise background. It was shown that the effectiveness of auditory detection of tone-impulse signals is invariant with respect to Doppler and shift transformation of the signal, whereas the number of waves serves as a characteristic parameter of the auditory system in the porpoise.
