Abstract
Conducto de guiado de gases (10) a lo largo de una vena de gas (V), que incluye un revestimiento de atenuación de ruido, incluyendo el revestimiento una pared (12) delimitadora de la vena de gas (V) y al menos una cavidad de resonancia (13), llevando la pared (12) perforados unos orificios (18) de establecimiento de comunicación fluida de la vena de gas (V) con la cavidad de resonancia (13) para la atenuación de ruido, caracterizado por el hecho de que los orificios (18) son de diámetros sensiblemente iguales y de que, estableciéndose dicho conducto (10) para guiar los gases desde aguas arriba hacia aguas abajo, el número de dichos orificios (18) por unidad de superficie de la pared (12) disminuye de manera continua a lo largo de la vena de gas (V), desde aguas arriba hacia aguas abajo, y teniendo dicha pared (12) una resistencia acústica sensiblemente constante a lo largo de dicha vena de gas (V), definiéndose dicho número de orificios por unidad de superficie de manera que dicha resistencia acústica sea constante.
