In the context of achieving a national set target of 60 GW by 2022, a study was carried out in Kayathar, Tuticorin district, Tamil Nadu, India on noise propagation from wind turbines. Acoustic and non-acoustic parameters were measured according to IEC 61400-11 at wind speeds of 4-13 and 0.7-8.6 m/s. The onsite measurements were compared with ISO 9613-2; this showed a difference of  5 dB(A) for every increment in the distance. An equation was derived to obtain sound pressure level (dB(A)) at the base of the tower for wind turbines at varying distance of measurement.

Wind energy embarks its development from the California era to the construction of huge onshore and offshore wind farms worldwide, highlighting the main challenges of wind energy applications while meeting the target 1000 GW of wind power by 2030. Though wind energy is considered a techno-economically matured energy, it is not entirely free from impacts on the environment and human health. Concurrently, large and small wind turbines are emerging even closer to human habitats, where acoustic noise would be of greater concern. Noise regulations and standards can effectively and fairly facilitate decision-making processes if developed and followed properly. For instance Denmark has a special legislation concerning wind turbines, while others like Sweden, and have used recommendations originally developed for different noise sources. In Germany, the noise level could be related to absolute level or background noise level (standardized, measured or related to wind speed) as in France. There showed a correspondence between sound pressure level and noise annoyance in the field studies performed across the globe among people living in the vicinity of wind turbines. Globally the annoyance and adverse health effects are analyzed by approaches such as epidemiological studies that rely on masked survey and clinical case studies. Wind turbine noise its propagation, relevant regulations, and impacts from wind farms were reviewed in this paper by summarizing existing studies. The intention of this paper is to provide state-of-art about wind turbine noise associated with wind turbines/farms to developers and planners.

India holds the fourth position in terms of installed wind power with an installed capacity of 40.788GW in July 2022. The country has set itself a national target of 60 GW by 2022. Wind energy still leaves small-scale impacts on the environment and human health. Advanced technologies emerged to make quitter turbines, still, the noise emitted is a cause of concern, especially in the habitats close to the installations. The present study aimed to assess the sensation of annoyance due to the wind turbine’s (WT) noise. in the adjoining inhabited area. An interactive questionnaire survey is conducted in six villages from the three districts in the state of Tamil Nadu. The study group comprised 47 subjects belonging to different age groups profession. The basic objective of conducting the health survey is to understand the influence of wind turbine noise (WTN) on the lifestyle of the common masses residing in the surrounding wind farms. While framing the legislation, noise annoyance due to WTN should be considered with utmost importance, since WTN is more distressing than common sources of noise. From the social and psycho-acoustical survey, it was found that sleep disturbance due to ambient noise is more concern, and also the adult population who participated in the survey attributed the loss of rainfall as the main problem faced due to the advent of the WTs and the Noise from the WTs
