Wind passing an object makes noise. It is unavoidable. Most wind-induced noise is broadband, unobtrusive, and often arguably even pleasant (e.g. wind through the leaves of a tree). However, under the right conditions, wind interacting with certain geometry can result in tonal resonance (e.g. a hum, whistle, wail, or screech – sometimes heard miles away). For nearby occupants, and neighbors, this can result in significant annoyance.
This webinar will look at how tonal wind-induced noise is generated, and the architectural features that are most often the culprit. We will also look at typical ways to mitigate or reduce the risk of noise, and review some particularly interesting case studies.
- To understand what aeroacoustic (wind-induced) noise is, and why is it a potential issue in building design.
- To understand the three mechanisms of concern for generating wind-induced noise.
- To learn typical façade and building features susceptible to these mechanisms.
- To learn typical methods to avoid issues, or to reduce the risk of wind-induced noise annoyance.
