Examples of silencer configuration are presented. Circular silencers with sound absorbing centre bullets are more commonly used in HVAC system ducts than simple lined circular ducts. Simple lined ducts are also shown, for completeness. The main aims for HVAC system duct designers are twofold, namely, to compute the silencer insertion loss spectrum for a given silencer configuration and to calculate the pressure drop across the silencer for a given face velocity. The development of a software for circular and annular duct silencers is also presented in this work
