Звуковая иллюзия - Парикмахерская - текст песни, слова, перевод, видео

The binaural effect - (from lat. Bini - pair, two and auris - ear), the ability of humans and animals to determine in which direction the sounding body is due to the presence of 2 sound receivers - ears. The sound passes to the ear, facing the source, a shorter path, so the sound waves in both ear canals differ in the phase (time of the arrival of this phase) and the amplitude (strength) of sound vibrations. The sound of different heights is perceived in different ways: for low sounds (up to 1,500 vibrations per second), the direction to the sounding body is determined most accurately and almost entirely by the difference in the time of the arrival of this phase of sound vibrations; For high sounds, in which a significant role is played by the difference in sound power in the right and left ear, the definition is less accurate.

The difference between the phase and intensity of perceived sounds leads to the difference in pulses entering the central nervous system from the right and left ear, which makes it possible to determine the direction of sound.
