Improvement of the way for taking into account the interactions between porous media for the design of multilayered acoustic structures with the simulation software SILDIS®
- Details
Taking into account the interactions between porous media for the sizing of multilayer acoustic structures is still a subject of questioning for specialists in Research and Development in the acoustics sector.
Porous media are the basis of most of multilayered acoustic structures generally used to form many products and construction systems for applications related to noise control: soundproofing panels, absorbing linings, dissipative silencers, etc ...
The feature of some porous media is to...
Integration of the computation of the acoustic performance of rectangular ducts and of circular ducts walls to the simulation software SILDIS®
- Details
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...
