We have shown experimentally the promising way to dolphin and man communication using video and acoustic
equipment by the beluga dolphins reaction to various scenarios presented. For the demonstration of these scenarios, a special
underwater monitor was engineered. The participated animals’ interest to different pictures and sounds revealed itself in a
sharp increase of the dolphin retention time at the screen (up to 7 minutes). The animal's acoustic response to the
demonstration of its own image with the use of a web camera consisted of the frequency wideband impulse packets sequences
of varying lengths with internal time-pulse modulation. The analysis of the recorded signals made it possible to distinguish
three main temporal structures, consisting of repetitions and permutations of such packets in time.
