Wind causes the generation of sound. The movement of air causes movements of parts of natural objects, such as leaves or grass. These objects will produce sound if they touch each other. Even a soft wind will cause a low level of environmental noise. If the wind is blowing harder, it may produce howling sounds of varying frequencies. This may be caused by the wind blowing over cavities, or by vortices created in the air downstream of an object. Especially on high buildings, many structural parts may be a cause of annoying noise at certain wind conditions. Examples of these parts are balconies, ventilation openings, roof openings or cables.
Ashley is relocating to Chicago for a new job. She is currently looking for a place to live and is considering two different apartment buildings, Suncrest Villas and Highland Heights. The apartment at Suncrest Villas is on the first floor of the building and the apartment at Highland Heights is on the top floor of the building.
Will the noise from the wind in the Highland Heights apartment be louder or softer than the Suncrest Villas apartment?
