ITS offers powerful solutions at a reasonable cost in response to all the needs in the matter of soundproofing (preventive or curative) to limit noise emissions by the means of equipment whose quality of design and of execution meets the highest level of requirement in this area for an efficient fight against noise in the context either of compliance to the legislation or of improvement of working conditions or of compliance with legislation or of improvement of the quality of the acoustic environment. Robust constructions and quality finishes ensure high durability.

 
Noise limitation in energy sector
the limitation of noise emissions
in energy sector
is one of the specialties of ITS
 

The energy sector (e.g. production, processing) is an important area of activity for ITS because it involves numerous and powerful noise sources for wich challenges of all kinds (in particular technical ones) are very important when it comes to the limitation of noise emissions, in a context of restriction of exposure to noise of workers at a site or for not exceeding the permissible emergences (the two issues are often combined).

The main applications of ITS in relation to the limitation of noise emissions in the energy production sector are related to motors (electric or thermal) or combustion turbines and related equipment (generators, transformers, compressors, vents decompression of fluids).

ITS can intervene to carry out an on site audit in terms of noise emissions (if required: with acoustic metrology), to size and to commercialize devices of limitation of the noise.

All related features in connection with aerodynamics, fluid mechanics, thermal insulation, mechanical resistance ... are taken into account on the occasion of the design and of the execution of soundproofing equipment according to technical needs and regulatory requirements of each project.

Enclosures (noise hoods, soundproof buildings)

ITS offers enclosures (noise hoods, soundproof buildings) for gas turbines or steam turbines, for generators, compressors, generator sets, auxiliaries...

A wide range of technologies and services for the limitation of noise emissions in energy sector

ITS offers soundproofing products and equipment for noise limitation in energy sector (protection of workers and environmental protection).

Such means are part of a program of technical measures to reduce exposure to noise, which must be considered (in noisy workplaces) for the protection of workers [1], and to reduce noise impact for environment [2], which must be considered (e.g. in and around noisy industrial sites) to preserve the tranquility of the neighborhood ; the technologies and services offered by ITS aim to ensure the compliance of installations in terms of the limitation of noise emissions in energy sector.

On-site measurements, design, construction (with or without installation) are part of the range of products and services marketed by ITS in terms of limitation of noise emissions in energy sector.

end FAQ

[1] in Europe, employees exposure to noise is regulated by the European Directive 2003/10/EC, which considers as indicators:

  • the level of daily exposure to noise L EX, 8h: 80 dB (A) and 85 dB (A) are the thresholds, lower and upper respectively, triggering the action, 87 dB(A) is the limit value
  • the peak sound pressure ρpeak : 112 Pa ie 135 dB(C) and 140 Pa ie 137 dB(C) are the thresholds, lower and upper respectively, triggering the action, 200 Pa ie 140 dB(C) is the authorized limit value

[2] in France, a limit is set by a prefectural decree e.g. 60 dB (A), and the emergence i.e. the difference between the equivalent continuous pressure levels weighted A of ambient noise (installation in operation) and of residual noise (in the absence of noise generated by the installation, but measured over its operating period) is legally limited - depending on the case to 5 or 6 dB(A) during the daytime and to 3 or 4 dB(A) during the night period
