Wind noise can be generated at screens, gaps, openings, edges and slots, or even inside buildings. These noises are often airborne whistles, roars and whines from relatively small components. In this event the consequence is likely annoyance of occupants.
Structure Borne Response
Some structure-borne vibrations can be caused by wind’s effect on building attachments such as fins, blades, screens and masts. They sound like hums, engines or are more felt than heard. These can be the more dangerous since the forces can be large and component metal fatigue is a real possibility.
Mostly occurring under large roofs, but also where metal facades or metal components of facades (e.g. sun louvres) are attached to the structure.
Vipac’s Desktop Study determines the expected wind-induced noise, saving you re-installation and redesign costs, while the Wind Tunnel allows for full scale measurement of building components to determine the expected decibel level for various wind directions. In one notable case, Vipac was commissioned to advise on the wind noise generated by attachments on the building facade of a public hospital, which led to a disturbance for patients trying to recover.
