Abstract

PROCEDIMIENTO Y APARATO PARA LA DETECCION DE UNA FUENTE ACUSTICA EN UNA ESTRUCTURA INDUSTRIAL. EL APARATO CONSTA DE UN CAPTADOR ACUSTICO (3) COLOCADO EN EL AIRE, CERCA DE LA CANALIZACION (1), QUE RECIBE LA ONDA AMBIENTE (5) EMITIDA POR LA FUENTE ACUSTICA; Y DE UN SEGUNDO CAPTADOR ACUSTICO (4) QUE ESTA ACOPLADO ACUSTICAMENTE A LA SUPERFICIE DE LA CANALIZACION (1), EL CUAL RECIBE LA ONDA DE TENSION (6). EL PROCEDIMIENTO CONSISTE EN MEDIR EL INTERVALO DE TIEMPO QUE SEPARA LA RECEPCION DE LA ONDA DE TENSION (6) DE LA RECEPCION DE LA ONDA AMBIENTE (5). DE APLICACION A LA VIGILANCIA ACUSTICA.
