Building Air Leak Noise Diagnosis & Cure
How to Diagnose, & Cure Noise Problems in Building Interiors
- POST a QUESTION or COMMENT about diagnosing the source and finding the cure for noises or sounds in or around buildings and their systems
Building air leak noise troubleshooting:
Causes & cures: track down drafts, hisses, hums, or other noises or indications of air leaks in buildings. Our page top photo of a poorly-closed attic pull down stair indicates a source of both heat loss and wind or air movement in a building.
These articles discuss building noise control: how to inspect, diagnose & cure noise or sound problems in homes or commercial buildings. We also discuss methods of sound or noise control in buildings during construction or as a building retrofit.

Air Leaks: How to Track Down Air Bypass Leak or Air Leak Noises in buildings
AIR BYPASS LEAKS in buildings may in some instances produce not only drafts and high energy bills, but actual sound as air moves through building openings under windy conditions.
- Air leaks at windows or doors,
in high wind conditions, can produce a hissing or a howling sound.
See WINDOW & DOOR NOISES.
Also see WIND NOISES at BUILDINGS - BLOWER DOORS & AIR INFILTRATION - are used to measure air leaks, equivalent leakage area (ELA), and air changes per hour (ACH) in a building
- Air leaks in ductwork
often make a roaring or hissing sound.
See LEAKY DUCT CONNECTIONS and also see VIBRATION DAMPENERS - STAIN DIAGNOSIS on BUILDING INTERIORS, how to diagnose stains on walls, floors, carpets, and how to determine the stain source - these articles can help track down air bypass leaks because moving air through soft materials (insulation, carpeting) or along surfaces (walls, ceilings) will often deposit dust or debris particles showing the locus of air leaks or movement.
- Also see WIND NOISES at BUILDINGS where we point out that wind can move building components (rattles, squeaks, roars, hisses) or increase leaks through building openings (hisses)
