[Efficiency of dolphin auditory perception in relation to time characteristics of the signal].
Experimental data are presented on evaluating the efficiency of auditory perception of the dolphin Tursiops truncatus of tonal signals of different duration and of the fixed energy on the background of Gauss obstacle. The dependence of percepting properties on time characteristics of the signal are stated. A comparative analysis of the efficiency of dolphin auditory system with that of the coordinated filter is carried out. Biological receiving systems are shown to be adaptive. The self-tuning linits of the dolphin auditory system at a given level of the possibility of correct detection are determined.
