A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces …
Sound Attenuators silencer terminology in HVAC System …
A sound attenuator also called duct silencer is used to reduce noise in any heating, ventilation, and air conditioning system. In a HVAC system, the potential noise sources are AHU, terminal units and room air outlets. The sound wave generated by these sources

A silencer for gas flowing through a duct includes a plurality of acoustical flat panels mounted in a duct and spaced from each other across the width of the duct. Each of the panels includes a core of rigid acoustical material encapsulated and heat sealed in polyvinyl fluoride to form opposed sides and opposed edges, all having smooth exterior surfaces.
Duct SilencerISTIQ Duct Silencers are designed to efficiently reduce noise by generator sets, air handling systems, compressor, blower system and all situations requiring air intake and outlet for these equipments to operate. A duct silencer should always
Fantech LD8 – Galvanized Steel Silencer for 8″ Duct – Easily-fitted silencer for circular ducts,fitted with a connection which is compatible with a standard spiral duct. The LD effectively reduces noise in the duct. Two silencers can be used together in installations where noise reduction is critical. For the most effective noise reduction, the silencer should be fitted immediately behind a
