Construction of a semi-anechoic room for acoustics R&D

Details

Published: 04 June 2025

In the automotive sector, as in many other sectors, sufficiently silent components, e.g. electromechanical, contribute to quality end products in a competitive market, in this case that of land vehicles, for which technological advantages count, when a buyer makes a choice taking into account criteria related to his comfort (brands must compete in ingenuity to stand out). Research and Development (R&D) work in acoustics is then essential to develop equipment whose noise is limited to meet...

Enclosing an industrial fan to reduce sound levels

Details

Published: 06 May 2025

Enclosing an industrial fan to reduce sound levels is a common measure for preventing or addressing objectionable noise, in accordance with regulations concerning:

• noise at work, e.g. in relation to European Directive 2003/10/EC, which is based on different indicators:
  • limit exposure values for workers to noise: exposure level L EX,8h = 87 dB (A) and peak sound pressure pcrête = 200 Pa or 140 dB (C) ref. 20 μPa /li>
  • higher exposure values for workers to noise triggering action...

Noise reduction of a technical facility

Details

Published: 02 April 2025

Reducing the noise of technical facities quite often motivates the recourse to a company specializing in soundproofing such as ITS, to prevent or treat nuisances linked to hardware located:

• outdoor e.g. in relation to energy production, refrigeration, waste disposal or in relation to more or less specific production or processing activities; the sound propagation outdoor is then at stake and can be reduced either "at the source" e.g. by means of enclosures (canopies) and silencers, or by...
