ABSTRACT:
A method for generating a low frequency electric stimulus signal is carried out by generating electric stimulus signal to provide electric stimulus to a biological body or living body. Either the current or voltage, or both, can be controlled in accordance with sound volume levels supplied from a sound source to modulate the electric stimulus signal. The frequency of the electric stimulus signal is selected to be a low frequency.
A low frequency electric stimulus signal generating apparatus for applying electric stimulus to a biological body includes a control section and a current/voltage controlling section. In the control section, a sound volume level derived from a sound source is sampled at a rate at which the biological body can feel it in substantially real time. The respective sampled sound levels are converted into frequencies corresponding to low frequencies and output, and predetermined control information. In the current/voltage controlling section, current and voltage stimulus signals are frequency-modulated separately based upon the frequencies. The control section and current/voltage controlling section are included in a stimulus signal generating section.
