4.7.1.3 Silencers
To avoid fan noise being transferred via the duct system, silencers should be installed both on supply and
extract air.
To avoid noise being transferred between rooms via the duct system and also to reduce noise from the
duct system itself, installation of silencers before every inlet diffuser is recommended.
