On the one hand, dividers, if they consist of a sound-absorbing lining (some of which having an absorption coefficient of up to 100% at mid-high frequencies...
Reduction of the exposure to noise emitted by a single-facer corrugator
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...
Soundproofing of a Heating Ventilation and Air-Conditioning (HVAC) System
Thermal comfort and air renewal are fundamental features for a building (whether residential, tertiary or industrial) requiring a Heating Ventilation and Air-Conditioning (HVAC) installation often involving air flows that are often rejected outside, and therefore, if they themselves constitute a source of flow noise e.g. because of excessive fluid speeds or if they allow the propagation of noise of upstream components, may be in able to negatively impact the sound environment, especially in the...
