Noise reduction strategy and guarantees of a normative noise level in the environment

The analyzed industrial plant, located in the urban space, was increasing noise emission to the environment along with its development. At the same time, the noise-protected residential area was approaching the factory boundaries. At one point, the limit value was exceeded by more than 7 dB, and the plant received an administrative decision to meet the acoustic standards at night or to stop production. Within one year, a complete multi-stage reduction strategy was developed and acoustic protection was implemented to keep the noise level below 40 dB. Currently, in order to control the state of the acoustic climate, the plant constantly monitors the noise level and the background noise. This allows it to react on an ongoing basis in the event of increased noise emissions to the environment.

Our client’s primary need was noise reduction by 7 dB within 8 months. We provided the client with the guarantee of achieving this goal – we took the responsilibity to reduce the noise level in the environment below 40 dB. In order to maintain permissible noise level after the reduction, we were continously monitoring the acoustic climate around the plant.

Our working team was composed of 2 acoustics specialists, 1 measurement specialist and 2 constructors designing acoustic solutions. Experts from the Acoustic solutions production department and Acoustic solutions assembly department were also involved in the project. The specialists use assessment tools, such as Sound level meter, Intensity probe, Acoustic camera, CadnaA, QGIS and Inventor.

End results that we delivered to the client included noise reduction strategies as well as acoustic and noise monitoring solutions, ready to be implemented at the plant.
