In compliance with development of technology most buildings are now currently equipped with air conditioning systems which require large sections for distribution ducts with built-in silencers. At present this creates great presure on a minimization of the overall size of silencers and determination of their hydraulic resistances. In conclusion the paper presents a concept of the evaluation of silencers by means of a so-called quality factor which essentially covers both their acoustic and hydraulic properties." .
