Rectangular ducts and circular ducts are the basis for many products and construction systems for applications related to soundproofing: dissipative silencers, resonant silencers, etc ... . They also form the connection pieces which are often implemented on the occasion of the installation of silencers in ventilation systems for example.

The sound attenuation of the walls of such ducts must be taken into account for the design of equipments for which noise transmission through the envelope...
