Soundproofing and depolluting exhaust from generator sets (gensets)

Details

Published: 06 April 2024

ITS will participate in the soundproofing and depollution of the exhaust of 7 generator sets (gensets), with a unit power of 3.5 MW installed in a data center in Western Europe.

The targeted performances are as follows:

• a sound pressure level at 1 m limited to a maximum value of 85 dB(A)
• NOx emissions reduced to a maximum value of 0.5 mg/Nm3

They will be obtained by installation, in the form of a multifunctional skid, of:

• an exhaust silencer (the metal parts will be made of stainless...

Soundproofing a school catering room (canteen)

Details

Published: 15 March 2024

ITS participated in the soundproofing of a school catering room (canteen) near Bourg en Bresse, in the Auvergne Rhône Alpes region.

Measurements of the reverberation duration (carried out with a noise generator and a sound level meter) had revealed an amplification of sound levels resulting from a lack of sound-absorbing surfaces in the considered premise (coverings such as tiled floors, painted walls, ordinary under-roof generally have a sound absorption coefficient much closer to 0 than to...

Lowering sound levels at an industrial site

Details

Published: 01 February 2024

French regulations regarding the limitation of environmental noise stipulate the following, with regard to a Facility Classified for Environmental Protection (FCEP):

• if the ambient noise level in the Regulated Emergence Zones - REZ - (including installation noise) is between 35 dB(A) and 45 dB(A) then the admissible emergence is 6 dB(A) during the day and 4 dB(A) at night
• if the ambient noise level in the Regulated Emergence Zones - REZ - (including installation noise) is greater than 45...
