This improvement has been achieved through the retrofitting of sound absorbing wall panels and a noise damping screen on one of the punching machines at the site.
The ‘makeover’ has resulted in a sound level reduction of between 4 and 13 dB (A)*, which is a considerable improvement as it means that in many cases hearing protection is no longer required in the workshop or offices due to the threshold of 85 dB (A)* being the point when protection must be used and the noise being produced falling under that. The site’s production manager Martin Andersson comments: “We immediately noticed an improvement and the results of the measurements are remarkable”.
Here below you can see the noise levels before and after fitting the noise reduction panels and screen:
|Noise level (dB (A))*|
|Punching machine (curtain lowered)||77.1||72.9||4.2|
|Punching machine (curtain raised)||87.7||79.9||7.8|
|Waterjet cutting machine (100mm plate, 10mm sheet)||100.1||87.1||13|
