“…It is possible to generate noise synthetically by means of emission synthesizers using physical and/or parametric approaches [1][2][3][4][5][6][7]. Adding recorded or synthesized (natural) background sounds to the noise samples helps to increase the degree of realism of the auralization.…”

In a variety of applications, e.g., psychoacoustic experiments, virtual sound propagation demonstration, or synthesized noise production, noise samples are played back in laboratories. To simulate realistic scenes or to mask unwanted background sounds, it is sometimes preferable to add background ambient sounds to the noise. However, this can influence noise perception. It should be ensured that either background sounds do not affect, e.g., annoyance from foreground noise or that possible effects can be quantified. Two laboratory experiments are reported, in which effects of mixing background sounds to foreground helicopter samples were investigated. By means of partially balanced incomplete block designs, possible effects of three independent variables, i.e., helicopter’s sound exposure level, background type, and background sound pressure level were tested on the dependent variable annoyance, rated on the ICBEN 11-point numerical scale. The main predictor of annoyance was helicopter’s sound exposure level. Stimuli with eventful background sounds were found to be more annoying than those with less eventful background sounds. Furthermore, background type and level interacted significantly. For the major part of the background sound level range, increasing the background level was associated with increased or decreased annoyance for stimuli with eventful and less eventful background sounds, respectively.

“…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]. Annoyance levels are also increased as a result of AM of the noise at the blade pass frequency (BPF), the low-frequency bias of the spectrum [126,134], the existence of tones and, possibly, infrasound. The persistent nature of the noise throughout the day and night is also a factor contributing to annoyance, as is the low ambient noise associated with many wind farm sites.…”

“…Investigations of the effect of wind farm noise on sleep can be undertaken in the houses of people living in the vicinity of one or more wind farms or in a sleep laboratory, in which participants are exposed to varying levels of wind farm noise, with and without various annoying aspects, such as AM, while they are attempting to sleep. During this time, measurement of physiological parameters enables the determination of awakening levels for sleeping participants exposed to varying levels and types of wind farm noise accompanied with varying levels of ambient noise [115,126,157]. All of these studies include the introduction of a number of physiological monitoring tools to continually test for sleep quality in the presence of wind farm noise at various levels.…”

“…For these reasons, it is recommended that future studies involve testing participants with both simulated as well as real recordings of wind farm noise. For those tests for which simulated noise is appropriate, Thorsson et al [126] provided details on how the simulated noise may be produced.…”

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.
