Flow noise in Air duct
Causes of Air Flow Noise in HVAC Ductwork
Air flow noise in HVAC ductwork is a common issue that can significantly impact building occupant comfort. This noise, often manifesting as whistling, rushing, or rumbling sounds, is primarily caused by turbulent air movement within the ducts.
Primary Causes
- High Air Velocity: Excessive air speed creates turbulence, leading to increased noise levels.
- Duct Design: Undersized ducts or abrupt changes in shape can cause air to accelerate, generating noise.
- Obstructions: Dampers, grilles, or other obstacles in the airstream create turbulence.
- Duct Material: Metal ducts tend to transmit and amplify noise more than flexible alternatives.
