Abstract

Se describe un método y aparato para la cancelacion activa del ruido de banda amplia y/o tonos de una sola frecuencia que emanan de una maquinaria rotatoria, tales como un dispositivo que mueve aire, al detectar las señales mecánicas y acusticas relacionadas en los mismos, y provocar que vibraciones de cancelacion sean aplicadas directamente a la maquinaria rotatoria mediante un transductor.
