General information relating to the performance of baffle (splitter) silencers

In the building sector or in an industrial context, noise limitation in air networks is often achieved by means of baffle (splitter) silencers i.e. constructions with a casing (in some cases: constituted by a duct, or an existing chimney flue) and, inside, with sound-absorbing elements (wool or foam with various surfacings and protections depending on the context) held...

Acoustics - Boosting silencer performance with SILDIS^® software

Details: Published: 30 April 2024

In the soundproofing sector, the selection (from a range of standardized products) or the development (custom-made) of silencers is a recurring engineering task in various contexts, the acoustic and aeraulic (aerodynamic) performance of such noise reduction devices being both multifactorial and antagonistic. In this field, experience then plays - of course - an important role, and appropriate tools determine the best technological choices.

The combination of geometric parameters e.g. thickness...

Noise attenuation - Cylindrical dissipative silencer with reduced pressure drop

General information relating to noise attenuation and pressure drop of dissipative silencers

Whether in the construction sector, or for industrial applications, noise attenuation in fluid networks is often achieved using dissipative silencers. The power of the sound waves is then reduced (mainly) depending on the distance traveled along their path in the open channels i.e. the airways (with on the periphery - and/or in the form of splitters - a packing of sound absorbing material) and also...
