Noise Generation and Noise Propagation

Wind turbines produce noise when operated (Wagner et al. in Wind turbine noise. Springer Science & Business Media, pp. 204, 1996; Tian et al. in Wind turbine noise modelling based on Amiet’s theory. Denver, CO, United States, 2013) which can be annoying and may cause adverse health effects (Harrison in Wind turbine noise. Bulletin of Science, Technology & Society, pp. 256–261, 2011). Noise with a frequency below the usual human hearing perception limit of 20 Hz is called infrasound. This chapter will not deal with noise generation and health issues but mainly wants to address the meteorological aspects of noise propagation which heavily depends on meteorological conditions.
