Noise limitation in a factory

Details

Published: 06 March 2025

Noise limitation in a factory can and must be considered from two complementary angles: on the one hand (internally) safety at work and on the other hand (with regard to the outside) protection of the environment, starting with the neighbourhood.

In terms of safety at work, it is a question of protecting personnel (e.g. those working in supervision or maintenance) from excessive exposure to noise, which could (eventually: irreversibly) damage their hearing and also cause accidents (potentially...

Enclosing an industrial fan to reduce sound levels

Details

Published: 06 March 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...

Construction of an anechoic chamber for acoustic testing

Details

Published: 04 February 2025

Acoustic testing is an important phase in the development of many products, whether to determine their sound power level or their sound pressure level at specified locations (to meet certain limits in this area or to develop a particular sound e.g. telephone ringing, door closing noise, acoustic discretion of moving vehicles).

A specific measurement environment is then necessary for the associated acoustic Research and Development (R&D) work, with in general (as main objectives):

• a...
