Decompression silencer

A decompression silencer is necessary to limit the noise of the thermodynamic process of venting a gas, or more generally: a pressurized fluid.

On the one hand, it is a question of protecting personnel, i.e. limiting their exposure to noise levels liable to cause significant hearing problems, sometimes irreversible (recognition of deafness as an occupational disease is only a very small consolation for the one who undergoes it).

On the other hand, the noise impact of a decompression vent must...

Soundproofing of a cogeneration unit

ITS participated in the soundproofing of a cogeneration unit at a petrochemical site located in North America.

It was a unit producing electricity and steam (used for industrial processes), built in a refinery, and giving pride of place to very noisy machines and equipment including a combustion turbine (of power greater than 40 MW) and an alternator, both of which were the subject of soundproofing work.

Cogeneration unit site constraints were distinguished by the need to respect noise levels...

Acoustics - simulation software SILDIS – silencers sizing online

When it comes to acoustics, as described here and there, the Module 1 of the simulation software SILDIS allows the sizing of silencers, for applications on the one hand in the building sector e.g. Heating Ventilation Air Conditioning (HVAC) facilities and on the other hand in the industrial sector e.g. aeraulic for air intake and exhaust of fans, combustion engines, turbomachinery by allowing (from input data relating to geometry, thermodynamics, fluid mechanics, and taking into...
