Abstract
LA INVENCION SE REFIERE A UN METODO PARA LA REDUCCION ACTIVA DEL SONIDO, EN EL QUE HAY UNA PRIMERA (10) Y UNA SEGUNDA (20) CORRIENTE DE VOLUMEN, DE LAS QUE UNA SE MODIFICA DE TAL FORMA QUE EN LA SIGUIENTE INTERFERENCIA DE LAS DOS CORRIENTES DE VOLUMEN (10,20) SE PRODUCE LA REDUCCION DE SONIDO. SEGUN LA INVENCION LA MODIFICACION DE UNA CORRIENTE DE VOLUMEN (20) SE REALIZA MEDIANTE MODULACION CON UN ESPECTRO DE FRECUENCIA DETERMINADO.
