Abstract

La invención se refiere a un dispositivo de atenuación acústica (1) para un turbocargador, o para un súpercargador, dispuesto a lo largo de un conducto de entrada de aire de un vehículo. El dispositivo de atenuación (1) comprende una tubería de suministro de gas (2) que tiene una pared periférica (21) y un diámetro (d2), la tubería (2) comprende al menos una cámara anular (3) definida por un diámetro (d3) mayor que el diámetro (d2) de la tubería (2), la, o cada, cámara anular (3) se sella por una pared (5) que comprende material poroso que se coloca en la extensión de la pared periférica (21) de la tubería (2), de acuerdo con un diámetro (d5) prácticamente igual al diámetro de la tubería (2), con objeto de permitir que fluya el aire entre la tubería (2) y la, o cada, cámara periférica (3).
