NEW VIDEOS FOR THE DETERMINATION OF LWA Sound Power
The determination of the sound power, LWA, of a product, required for the Machine Directive and related regulations, requires an expensive test chamber. An often used alternative is to use the sound intensity measuring method. This permits accurate measurements even in the presence of background noise.
This method is demonstrated in the two videos presented here, one in English (Bas Möllenkramer) and one in Dutch (Bert Roozen)
