Primary Outcome Measures

Name	Time	Method
The main outcome of the survey is to identify 4 groups according to overnight noise exposure type and level of complaints into; highest complaint quartiles in wind farm and traffic noise exposure groups (WFNQ1 and TNQ1), lowest quartile complaints in the wind farm exposure group (WFNQ4) and a quiet rural exposure control group (CN). Level of complaints will be generated using a combination of scores from the Pittsburgh Sleep Quality Index, (PSQI); Insomnia Severity Index, (ISI); Epworth Sleepiness Scale, (ESS); quality of life (EQ-5D) and Functional Outcomes of Sleep Questionnaire (FOSQ). In addition, responses to general night-time noise questions directly relevant to sleep and proximity to noise sources within the past 3 months will be used to identify residents who indicate high vs. low complaints.[Once a minimum of 400 responses to surveys are collected, or at least 200 from wind farm-exposed areas & 200 responses from wind farm-naive areas.]

Secondary Outcome Measures

Name	Time	Method
To describe self-reported sleep in different exposure groups using the Pittsburgh Sleep Quality Index, (PSQI); Insomnia Severity Index, (ISI); Epworth Sleepiness Scale, (ESS); quality of life (EQ-5D) and Functional Outcomes of Sleep Questionnaire (FOSQ).[Once a minimum of 400 responses to surveys are collected, or at least 200 from wind farm-exposed areas & 200 responses from wind farm-naive areas.];To describe overnight-noise outcomes in different exposure groups using the general night-time noise questions directly relevant to sleep and proximity to noise sources.[Once a minimum of 400 responses to surveys are collected, or at least 200 from wind farm-exposed areas & 200 responses from wind farm-naive areas.]
