Measurement and noise analysis ACOUSTIC DIAGNOSTICS Due the proven noise hazardous influence on health, but also on a environment, demands for constant reduction in noise are pushing research in this area. This requires an analysis of noise sources and knowledge of its characteristics. Identification, location, quantification and evaluation of the partial sources represent key steps in order to reduce overall noise. Using specialized measuring equipment (acoustic camera) we provide development services and diagnostic testing's as well as solving the problems of acoustic noise detection and noise...
