Human response to wind farm noise compared to road traffic noise based on focused listening tests (Poner el Abstract solo)

Although various wind farm noise (WFN) complaints have been raised, the evidence regarding the effect of WFN on health is still not well established, compared to road traffic noise (RTN). In addition, WFN dose-response relationships for sleep have not been derived before, either on a subjective or objective basis. This paper presents dose-response relationships for WFN and RTN as well as their effect on annoyance and sleep disturbance using stimuli measured at different distances from the respective noise source. The stimuli were reproduced using loudspeakers and the tests involved twenty-two participants who rated their subjective response via questionnaires. The results show that WFN can be more annoying and more likely to disturb sleep than RTN at the same A-weighted sound pressure level, especially when it contains amplitude modulation. Despite this, WFN is interestingly perceived to be quieter than RTN at the same A-weighted level. These results can help develop current allowable limits for WFN, which still vary considerably between jurisdictions.
