“…The higher audibility rates found for S1 suggest that a sourcespecific parameter like a metric reflecting the periodic sound pressure level fluctuation, often called amplitude modulation for the sake of conciseness, is more relevant. Recent research also showed that this apparent amplitude modulation is an important source of complaints [4] in the context of wind energy.…”

“…While it is well known that noise explains only a small part of the variance of annoyance due to noise-generating activities in general [3] and wind energy in particular [4], acoustics is a key factor in the acceptance of wind energy by the communities. There is clear empirical evidence that wind turbine noise can be a source of annoyance [4][5][6][7]. Due to the pressure to increase the installed capacity, over time one can expect that the density of wind farms per unit area will be increased and that the new wind farm projects will be located closer to populations.…”

While most of the countries over the world rely on sound-pressure-level-based limit values to regulate wind energy development, sound emergence as defined in ISO 1996-1 is used in a few national legislations but also in international guidelines. There is however no published evidence that sound emergence is a relevant noise descriptor for that kind of source, namely that there is a correlation between this metric and perception or annoyance. A listening test was carried out to evaluate the relative merits of sound pressure level and sound emergence as predictors of annoyance from wind turbine noise. The test samples consisted of 45 30-s wind turbine sounds at three different A-weighted sound pressure levels and five different signal-to-noise ratios. Thirty two persons rated the test samples according to the ISO 15666 standard scale in a dry room equipped with loudspeakers. The results indicate that short term annoyance is better predicted by A-weighted sound pressure levels than by sound emergence. It is also observed that sound emergence is a poor predictor of the audibility of wind turbine sounds.

“…Human response to wind farm noise is the subject of considerable past research as well as on-going research [121][122][123][124][125][126]. There continues to be disagreement among researchers as well as among the general public regarding whether or not wind farms are directly and/or indirectly responsible for adverse health effects [127][128][129][130]. However, it seems that wind farm noise is possibly more easily perceived and, compared with noise from other community sources such as traffic noise, railway noise and aircraft noise, wind farm noise is more annoying [122,[131][132][133].…”

This review is focussed on large-scale, horizontal-axis upwind turbines. Vertical-axis turbines are not considered here as they are not sufficiently efficient to be deployed in the commercial generation of electricity. Recent developments in horizontal-axis wind turbine noise research are summarised and topics that are pertinent to the problem, but are yet to be investigated, are explored and suggestions for future research are offered. The major portion of recent and current research on wind turbine noise generation, propagation and its effects on people and animals is being undertaken by groups in Europe, UK, USA, Japan, Australia and New Zealand. Considerable progress has been made in understanding wind turbine noise generation and propagation as well as the effect of wind farm noise on people, birds and animals. However, much remains to be done to answer many of the questions for which answers are still uncertain. In addition to community concerns about the effect of wind farm noise on people and how best to regulate wind farm noise and check installed wind farms for compliance, there is considerable interest from turbine manufacturers in developing quieter rotors, with the intention of allowing wind farm installations to be closer to populated areas. The purpose of this paper is to summarise recent and current wind farm noise research work and the research questions that remain to be addressed or are in the process of being addressed. Topics that are the subject of on-going research are discussed briefly and references to recent and current work are included.

“…Few relevant papers on wind energy conversion and their annoying effects are briefed here. The annoying effects of wind energy conversion were investigated by Pohl et al [29]. The study combined the methodology of stress psychology with noise measurement with an integrated approach and residents of a wind farm in Lower Saxony were interviewed on two occasions (2012, 2014) and given the opportunity to use audio equipment to record annoying noise.…”

The aim of the study is to present a brief overview of energy policy instrument for monitoring and evaluating holy places and their habitants with the aid of acoustic filters for sensors and transducers. A monitoring protocol for policy instrument is presented for noise protection and security from power systems. Methods of information and data collection are briefly elaborated. The power systems are classified as per source signals of solar power, electric power, light power, sound power, heat power, fluid power and fire power. The acoustic filters as per source of noise signals from power systems are defined. The filters are differentiated as per source signal of unwanted frequencies from solar power, electric power, light power, sound power, heat power, fluid power and fire power. Some examples of acoustic filters are mentioned as per source of noise signal. A slide rule for noise measurement is illustrated along with its noise grades and flag colors under limiting conditions. Some noise filtering results from various power systems of an outdoor duct are also tabulated. An overview of noise systems integration with command and control center is described. A brief discussion on management of holy places and their habitants through monitoring and evaluation is also mentioned.
