An improved method for attenuating sound and a sound attenuating device for use in a gas transportation duct, said device comprising a core of acoustically absorptive material (5) substantially enclosed within an impervious film (6) to prevent direct contact between the acoustically absorptive material and gas flowing through said gas transportation duct, wherein said enclosed absorptive material is maintained in position between at least two perforated facing plates (3) and further wherein there is provided between the perforated facing and the impervious film spacing means (7) to prevent contact between the film and the perforated facing and blocking means to impede the internal flow of air between the film and the perforated facing.
L'invention concerne un procédé pour atténuer le son et un dispositif pour atténuer le son dans une conduite de transport de gaz. Ledit dispositif comprend un noyau de matériau (5) à absorption acoustique compris sensiblement dans une pellicule imperméable (6) pour éviter tout contact direct entre le matériau à absorption acoustique et le flux de gaz traversant ladite conduite de gaz, où le matériau absorbant est maintenu en position entre au moins deux plaques de protection perforées (3). Entre lesdites plaques de protection et la pellicule imperméable, il est prévu des écarteurs (7) pour éviter tout contact entre la pellicule et les éléments de protection et de blocage pour entraver le flux interne d'air entre la pellicule et le parement perforé.
