Audio Isolator and Attenuator: Understanding Air Duct Noise

Round or circular ducts are generally better equipped to handle air pressure than angular ducts, which can pop and bang more easily due to their shape. The size, thickness, and shape of the ducts also play a significant role in determining how well they perform. Before searching for a solution, it's essential to identify and address any issues with the ductwork.

Other common causes of popping sounds include delayed ignition, undersized ductwork, or faulty connections between the trunk and plenum. However, air duct noise can also occur when the thin metal sheet within the ductwork expands due to sudden changes in pressure caused by airflow.

Interestingly, even clean ductwork can produce noises as the airflow causes the duct to expand differently than it would with dust and debris present. This can lead to a range of common sounds including booms, nags, squeals, buzzing, clicks, and pops.

These sounds typically occur once the system is turned on and conditioned air begins to flow through the duct. The 'speaking tube' effect, where startling pops and booms echo into previously quiet spaces, can be particularly frustrating and disturbing for those in the area.

So, how can you alleviate this problem? Air duct noise silencers are designed to help stifle these related noises and restore a peaceful environment. By understanding how air duct noise is caused and the various solutions available, you can take steps to address any issues and enjoy a more comfortable living or working space.
