Most of the examples in this paperĪre chosen from data for the Canadian Province of Ontario. Global capacity of 486.8 GW, which produced 3.7% of the Turbines in operation in the world at the end of 2015, with a The Global Wind Energy Council shows there were 341,320 wind Rapidly growing method of generating electricity. A new source of sound in the environment, notĭiscussed in these classic texts arises from wind turbines, a Well as Fastl and Zwicker in, "Psychoacoustics-Facts and Many, including Kryter in, "The Effects of Noise on Man" as The subject of annoyance from noise has been discussed by Sound Annoyance Special characteristics Īdverse impact Wind turbine Introduction Some consider “annoying” has little impact more than, “your gum chewing is annoying,” while for others, an annoying sound can mean loss of sleep, and loss of that restorative time itself has many documented adverse effects. Why annoying sounds matter is a complex subject. A key finding shows annoyance is related more to changes and characteristics at a particular time, rather than to longterm averages of sound. Development of modifiers to normal LAeq sound limits is suggested to improve the effectiveness of regulations. The comparisons included analysis of LZeq, LAeq, narrow band analysis, evaluation of amplitude and frequency modulation, and fluctuation strength. Recordings made in a controlled manner of environmental sound samples, such as flowing streams, wind in coniferous trees, or wind in bare or leafed deciduous trees as well as other sounds found in the environment, such as vehicles passing by on highways, aircraft overhead, and railway travel are compared with sound recordings from wind turbines. This paper categorizes wind turbine noise complaints based on face-to-face interviews with impacted individuals, and correlates logs of complaints to conditions at the time.
Studies such as the “Health Canada Wind Turbine Noise and Health Study” have documented noise annoyance complaints. A new source of environmental sound arises from wind turbines, a rapidly growing method of generating electricity. These "special characteristics of noise" include tonality, a non-random cyclical nature, pitch, roughness, rise time, and dominance of noise during sleeping hours when environmental noises diminish. Classic acoustics texts identify key points related to annoyance. Almost without hesitation, most people can identify a sound that is annoying to them, whether it might be fingernails on a chalkboard, a barking dog late at night, a mosquito buzzing in their ear, or their own particular example.
