In the operation of any industrial machineries, an important amount of energy is emitted in the form of noise, that can be measured as sound power level. The Acoustics Laboratory certifies then the sound power level for equipment manufacturers and industrial systems through noisy measurements in free field (at the client factory) or in reverberant room at the laboratory.

The certification of the sound power level and a lower level than the market requests are the preferred reasons in the choice of the consumer, as demonstrated by greater European interest in terms of labels and compliance with the applicable regulatory framework.
