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...

Noise reduction of a combustion turbine and a generator

Details

Published: 04 January 2024

ITS participated in the noise reduction of a combustion turbine and a generator in a power plant in Southeast Asia, designed for simple cycle operation. With a power greater than 80 Megawatt (80MW), this fzacilty is one of the smallest involving large capacity gas turbines (for some, the unit power can exceed 550 MW in a simple cycle and 800 MW in a combined cycle, which is not is not very far from a nuclear unit and notably allows faster construction and therefore commissioning of the energy...
