Noise Control for the Corrugated Cardboard Industry and the Paper Industry

The current noise laws (2003/10/EG) foresee new and more stringent regulations in the area of noise control in the corrugated cardboard manufacturing industry.
 
The noise sources considered in the corrugated cardboard industry besides corrugating machinery are also the glue unit, the slitter scorer, as well as the transversal knives and waste fan.
 
Because of the relatively high noise output level in the corrugated cardboard industry and the paper industry, a complete noise control enclosure of each individual machine is necessary not only to meet the noise requirements, but also to create a more employee-friendly work environment.
 
Additional noise control measures can also be incorporated in the corrugated cardboard industry and paper industry such as improvement of the workshop acoustics.
 
In the proximity to the corrugators, sound pressure levels up to 112 dB(A) have been recorded depending on line speed and cardboard type. 

In the paper industry the first step is to introduce noise attenuation quiet rooms in order to safeguard the operators of the paper manufacturing machines from the often very high noise level. 

Access, seals and a ventilation system are also very important factors in the corrugated cardboard industry which need to be addressed when designing a noise control cabin.
 
A good alternative to the enclosure of individual machines is a complete noise control enclosure of the entire dry-end.  In this way, a build up of sound reflection between different sound enclosures can be avoided and a cost effective solution can often be found.
 
In the corrugated cardboard industry a sure and thoroughly effective noise control concept needs to address all relevant sources of noise.
