Acoustic Treatment
BEIRENS designs, manufactures and installs absorptive and reactive made-to-measure silencers, in line with your requirements and operating conditions in order to treat transmission of noise through outlets or walls of exhausts. They are installed by our specialists, who are trained to work in all types of environments. Our experience in exhaust acoustics also enables us to refurbish existing silencers. Our acousticians can carry out spectral analysis on your site, in particular compliance with environmental constraints bound to the decree of 23rd January 1997. We identify and characterise the source(s) of noise and propose the best adapted solutions for your installation.

Boiler Silencers
Double-chamber resonator: This silencer is formed by assembling two volumes inside a section of the smoke flue (exhaust or chimney) through which all smoke flows. The transversal section of these chambers is greater than the size of the flue, hence the name «expansion chamber». Gas inlets and outlets of these silencers can be axial or ...

Beirens - Turbine Silencers
This type of silencer consists of a series of parallel baffles placed inside the smoke flue (exhaust or chimney) creating large contact areas that efficiently absorb low, medium and high frequency noises. The noise generated by turbine exhausts is significant (>130 dB) and therefore requires high-performance acoustic treatment. Each baffle is optimised to achieve the highest level of performance, while reducing pressure losses as much as possible. ...
