Wind noise refers to the unwanted sound created by air moving over and around objects, such as buildings or vehicles. This type of noise is caused by turbulence in the air that creates vibrations which are then transmitted through the air as sound waves. Wind noise can be a significant problem for those living near busy roads or highways, where it can create an annoying background hum. It can also affect those who live in areas prone to strong winds, such as coastal regions or mountainous areas. To reduce wind noise, various materials and technologies are used in the design of buildings and vehicles, including sound-absorbing insulation, double-glazed windows, and aerodynamic designs that minimize turbulence.
