Study and construction of an anechoic room for acoustic metrology

Details

Published: 01 September 2025

The acoustic comfort of a car is a major issue for manufacturers, contributing significantly to the brand image; it is made possible by the installation of sufficiently quiet components and sufficiently efficient noise insulation of the passenger compartment.

The development of these hardware and of suitable soundproofing systems requires specific acoustic metrology, for the evaluation - in a wide frequency range often 20 Hz - 20 kHz to reflect human auditory perception - of the sound pressure...

Reducing the noise impact of an industrial site is a major concern, both in terms of preventing nuisances that could be caused by excessive noise levels, and in terms of corrective actions, when they are required (designers, equipment suppliers and operators are interested parties in this issue).

With regard to the interior of the site, a major challenge is to protect employees and external personnel passing through (visitors, service providers) from the risks of hearing trauma that can cause...

Reduction of exposure to industrial noise

Details

Published: 02 July 2025

Reducing exposure to industrial noise primarily concerns two communities, separated by a property boundary:

• workers, with regard to their health. In this matter, European Directive 2003/10/EC (which can be considered a reference document beyond the geographical scope of the Member States) sets the limits of sound levels for the prevention of deterioration of hearing abilities (this is also beneficial with regard to the prevention of accidents at work which could be caused - in the case of...
