Področje projekta (angleško): The standard specifies silencer measurements in situ. Results obtained according to this standard cannot be compared to performance data obtained from laboratory measurements on ducted silencers according to ISO 7235, partly because of different test conditions and partly because of different definitions. The standard offers the opportunity to evaluate the acoustic performance of silencers under plant operating conditions. The standard can be applied to a) silencers which are installed either as a whole or in the form of individual baffles in the propagation path ...
