Integration of the sizing of rectangular silencers made of splitters (baffles) with a low total pressure loss to the simulation software SILDIS^®

Details: Published: 23 July 2013

A low total pressure loss is often a major qualitative criterion for a silencer (in particular: rectangular), influencing its dimensions, and therefore its price.

Rectangular silencers with splitters (baffles) are the basis for many applications related to soundproofing: dissipative silencers, resonators, etc ... . Their total pressure loss (sometimes referred to as back pressure) is a key feature for the design of silencers because it affects in particular the size of soundproofing equipment...

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: Published: 30 November 2012

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...
