Everything in this world is exposed to hesitations. A human is able to percept only narrow spectrum of al lhesitations that exist. For example, air hesitations can be percepted by the human in the interval of 20 to 20000 Hz only. However, the sound belonging to infra- or ultra-sound wave bands also exists. An ear can’t fix such sounds, but they also influence the human. It is known that infrasound (16 Hz) affects human behavior, psychology and perception. In all, human senses only a 3 % of all sound hesitations and vibrations affecting him. Human is not only exposed by external hesitations but radiate them himself due to his inner processes. Hesitations radiated by human are individual. If external hesitations are not in harmony with the inner ones – then the external hesitations overwhelm the inner ones. As a result the processes generating those hesitations are suppressed too. This program is designed to compute your individual hesitations and to represent them with the external ones in a simple form of hearable sounds. So you can evaluate the harmony of the result. You can learn whether your biorhythms correspond to the external vibrations. Besides, the registered version contains a special tool for evaluating the harmony of two streams of inner hesitations. That means you can to clear up a question about the potential compatibility of two persons.
