Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO PARA AMORTIGUACION DE RUIDO EN CONDUCCIONES TUBULARES, CON UNA ABERTURA (4) DE SALIDA CON RADIACION DE RUIDO EN EL EXTREMO DEL TUBO SEGUN UNA LONGITUD DE ONDA PRINCIPAL BLANDA DE RESONADOR DE SILBATO, DETERMINADO EN LA FUENTE DE RUIDO EN FORMA DE UNA CAPERUZA (1, 10, 11) DE COBERTURA CON UNA O MULTIPLES PAREDES (3) LATERALES Y AL MENOS UNA PARED (2, 2'') FRONTAL. PARA ELLO UNA PARED (3) LATERAL O PARED (2, 2'') FRONTAL SE COMPONE AL MENOS DE UN MATERIAL PERMEABLE AL GAS CON UNA RESISTENCIA DE CORRIENTE ESPECIFICA LONGITUDINAL COMO VALOR MAS ALTO DE 500 KNS/M{SUP,4}. COMO PARED PERMEABLE AL GAS SE UTILIZA CON PREFERENCIA UNA PLACA AGUJEREADA, CUYA PORCION DE SUPERFICIE AGUJEREADA ALCANZA COMO MAXIMO 40 %, CON REFERENCIA A LA SUPERFICIE COMPLETA DE ESTA PARED. DE ESTA FORMA PUEDEN SER MANTENIDAS EN CONDUCCIONES TUBULARES RECORRIDAS POR GAS UNA PERDIDA DE CARGA RELATIVAMENTE PEQUEÑA DE SALIDA A TRAVES DEL AMORTIGUADOR DE RUIDO.
