Building Regulations Part F 2010 have driven system designers to take into consideration noise sensitive areas where ducting passes over or through such as bedrooms and living rooms.
Noise sensitive areas (living rooms and bedrooms) should not exceed 30 dBA. Less sensitive areas (kitchens and bathrooms) should not exceed 35dBA.

Planning Assessments PPG 24
Local authorities can impose planning conditions (PPG24) on projects requiring the designer and developer to deal with aspects of the noise. This will normally result in potential noise ingress through the ventilation system if penetrating the external facade.
Incorporating attenuation will ensure compliance is achieved. This can assist in preventing external noise ingress transmitting through the duct and limit cross talk between rooms.
These new high flow attenuators allow flexibility for designers to choose the right noise solution to suit your application and minimise system resistance.
