Abstract

L'invention concerne un ensemble d'absorption acoustique (1) comprenant un corps (2) de forme tubulaire présentant des extrémités fermées respectivement par une première et une deuxième nappes souples (3, 4) tendues micro-perforées, et au moins un diaphragme plan disposé à l'intérieur du corps (2) tubulaire, entre les nappes souples (3, 4) micro-perforées, de manière à délimiter deux espaces (6, 7) entre lesdites nappes.
