Abstract

LA INVENCION SE REFIERE A UN ELEMENTO ACUSTICO Y A UN METODO PARA EL PROCESO DE SONIDO. EL ELEMENTO (1) ACUSTICO ESTA FABRICADO DE UNA PLACA (2) ESTATICA POROSA QUE ES ELECTRICAMENTE CONDUCTORA O ESTA RECUBIERTA DE METAL SOBRE AL MENOS UNA DE SUS SUPERFICIES PARA HACERLA CONDUCTORA. UN DIAFRAGMA AMOVIBLE (3, 3A, 3B) ESTA FIJADO A LA PLACA ESTATICA (2). PARA MEDIR, ASI COMO PRODUCIR PRESION SONORA Y VELOCIDAD DE LAS PARTICULAS, EL EQUIPO COMPRENDE DOS PARES DE LOS ELEMENTOS (1) ACUSTICOS MENCIONADOS ANTERIORMENTE. LOS ELEMENTOS QUE SIRVEN COMO ELEMENTOS DE CONTROL DE LOS SENSORES SIRVEN TAMBIEN COMO ACTUADORES PARA ATENUAR Y ABSORBEN SONIDO.
