Duct Silencers

Fan and airflow noise travels along the ducts into the rooms. A silencer absorbs it inside the duct: it is lined with sound-absorbing material behind perforated steel that lets air pass freely.

Where they are installed

Usually after the fan or air handling unit, and where ducts enter noise-sensitive rooms — bedrooms, meeting rooms, hotel rooms.
