Soundproofing of a production line

Details

Published: 21 July 2017

In a workshop related to metal processing, a production line constitutes a source of noise which, if one neglects its soundproofing, places in a situation of auditory trauma a number of workers much greater than that corresponding only to the operators directly dedicated to the conduction of the line in question.

Indeed, for a machines such as a press or a lath (a fortiori: if combined e.g. for metal machining works), noise emissions can be so high that they are likely to impact very large...

Removal of an anechoic chamber

Details

Published: 27 June 2017

Many sectors of activity (in particular in relation to advanced technologies) require test stations for Research & Development (R&D) in acoustics that must adapt to space constraints, in particular for companies which are evolving a lot, for which re-arrangement projects linked to variations in capacity or organization are not unusual.

Such means of testing must then be capable of being disassembled, transported and re-installed, in some cases: on the same industrial site, but in...

Noise reduction of an industrial chimney (stack)

Details

Published: 19 May 2017

An industrial chimney (aka stack) can constitute a source of very powerful noise potentially causing noise pollution for the environment, near or far, a fortiori if it is very high.

In the case of hot gases, the exhaust of gas turbines or combustion engines is often the source of a noise which, if not sufficiently attenuated by the components of the network, is present at the outlet of the chimney (stack) in an undesirable manner.

Hot or cold, gas flows are also often vented to the atmosphere...
