Ducting Explored - Acoustic comfort for air ducts

Why should I be concerned about noise?

Noise is commonly defined as a loud or unpleasant sound that causes a disturbance. Studies have shown that noise exposure increases general stress levels and aggravates stress-related conditions such as high blood pressure, coronary disease, and migraine headaches. It also impacts sleep, affecting a person's mood, productivity and learning the following day. 

 

How do air ducts contribute to a noisy environment?

Air ducts are often made from materials that vibrate easily. Due to mechanical impact, such vibrations and sounds that can be transmitted through the air are carried by the air ducts to other parts of the building it supplies clean air to. If you hear the whooshing of the airflow or the loud footsteps of someone walking along a corridor, there is a chance that air ducts are carrying these noises to your location.

 

What can I do to reduce this noise?

Insulation helps to lower the overall noise level in a building as it absorbs the sounds carried by air ducts. Fibre-free duct liners, such as open-cell elastomeric foams, have visco-elastic properties that can isolate vibrations and dampen noise. This is more effective as compared to fibre-based duct liners that reduce noise through the friction caused within the material when sound enters the space between the fibres.
