Quiet design
In ventilation systems, noise stems from a variety of components such as the fans or the fire dampers. To comply with a specified noise level, sound attenuators are added to suitable locations in the ventilation system. The sound attenuators should have adequate silencing capabilities, low air resistance and be as small as possible.
