Wind-induced Noise (Aeroacoustics)
Wind flowing across, around and through building features can result in audible tones arising from aeroacoustic phenomena such as resonances, Aeolian tones, cavity flows, vortex shedding and its interaction upstream and downstream with edges and corners (edge tones), flow induced vibration to create coupled “sounding board” effects. These tones are a result of complex interactions between the wind flow field and geometry of the building elements. This condition can cause significant disruption with aeroacoustic noise often audible at several hundred meters away from the source building. A review of possible wind-induced noise mechanisms is therefore essential during design so that costly mitigation measures are avoided.
Novus personnel apply advanced modeling tools such as computational fluid dynamics and wind-tunnel testing to assist you with controlling wind-induced noise.
