Apparatus for applying the electrical stimulus to the biological body comprises a control section (30) and a current/voltage controlling section (40;50). In the control section (30), a sound volume level derived from a sound source (16) is sampled at a rate at which the biological body can sense it in substantially real time. The respective samples sound levels are converted into low frequencies and are output, together with predetermined control information. In the current/voltage controlling section (40;50), current and voltage stimulus signals are frequency-modulated separately based upon the respective frequencies. The control section (30) and the current/voltage controlling section (40;50) are included in a stimulus signal generating section (10).
