Electromechanical mechanism for sound wave control that is essentially characterized by an electric circuit with switching means and its own source of electric power by battery that drives an electric motor with possibilities of current inversion through a relay that allows two positions to decrease the amperage passing through the sameproduced by the vibrations of a membranecaptora of the sound waves of a certain amplitude that cause the imperfect contact of the terminal that communicates with the relay through its corresponding solencide.
