Noise reduction in workplace

Noise reduction in workplace is one of the actions that should be considered in the case of a daily noise exposure level above 85 dB (A) and / or a peak sound pressure level beyond 137 dB (C) pursuant to Decree No. 2006-892 of 19 July 2006 (in France).

However, many machines are, without / before soundproofing, likely to cause such noise levels, which then expose employees to auditory risks: in the case of sufficiently powerful noise sources, impacted workplaces can be located not only nearby...

Reduction of the exposure to noise emitted by a single-facer corrugator (cardboard industry)

A single-facer corrugator is a machine allowing the production of single-sided corrugated cardboard from a web of paper which is formed between two cannulated cylinders, which are heated with saturated steam, and from glue, applied by the means of a cylinder in rotation.

This process is accompanied by significant noise emissions, likely to induce the exposure of workers to the risks due to noise, which is regulated by the Decree n ° 2006-892 of July 19, 2006 relative to the prescriptions of...

Industrial acoustic insulation

In a corrugated cardboard production plant, a single-facer corrugator is a source of noise for workers such as line drivers and other operators and technicians involved in various sub-assemblies (e.g. reel stand & splicer, bridge, preheater, gluer, cutter, slitter scorer), in particular for monitoring the manufacturing process and for maintenance.

If they are in the same workshop, they are often exposed to noise levels above the limit triggering the action i.e. 80 dB (A), in France, within...
