69.3 Hz Exalt Sign
Its frequency is expressed in Hertz. This corresponds to the number of vibrations per second: if there are few we hear a low sound, when there are more we hear a high pitched sound. These waves, some of which are inaudible, propagate in us and resonate with our organs (the ear is the most obvious sensor) but also with the cells of our body. How is it possible? Sound vibrations, when propagated, act on matter. This is what the work of several researchers has shown.
