- What is the research question?
This study will be the first direct investigation of real-world wind farm noise compared to traffic noise effects using gold-standard assessments of sleep (i.e., polysomnography that measures brainwaves and other physiological factors to determine sleep/wake). The aim is to assess self-reported (subjective) and direct objective measures of sleep quality in a carefully controlled laboratory environment to investigate relationships between noise, sleep disturbances and other factors.
- What will the participants be expected to do?
Participants will be booked to attend the sleep laboratory for 7 consecutive nights ((plus additional recovery nights if required to recover from the experimental nights), based on their availability and the availability of the laboratory. They will reside in a private, self-contained bedroom (like a hotel room, with a king-size single bed, ensuite and shower facilities) and would be welcome to use a shared lounge, kitchen and washing facilities.
We will post a sleep monitoring device (like a FitBit) and sleep diary, that participants will be asked to use for 2 weeks prior to their laboratory stay.
Upon arrival at the sleep laboratory on the very first evening, participants will be familiarised with the facility and the experimental procedures and given an opportunity to settle into your bedroom. After dinner, research personnel including trained sleep and sound technicians, will set-up participants with sleep-recording devices. Participants will then undertake a listening test to examine annoyance and acceptability for sleep toward different noise types, and complete questionnaires.
At their usual bedtime, lights will be turned out in participants’ bedrooms for sleep, and noise may or may not be played during the night.
Each morning, we will collect 4 saliva samples at 15-minute intervals as a measure of stress-response (cortisol, and a 5th sample in the evening). Participants will then be asked to complete a sequence of computerised tasks and questionnaire.
On a single occasion, a small hair sample will be collected to measure long-term stress and, on another occasion, participants will attend a 60 minute clinical audiology appointment at the Flinders Medical Centre Audiology Clinic.
- What benefits will participants receive?
Full accommodation, all meals and snack will be provided during the stay.
Participants will receive $100 per night reimbursement for their time, plus $200 upon successful completion of all 7 overnights. Participants travelling from rural areas will receive $400 for travel expenses and $100 for urban travel to the laboratory.
- Location of the study
Adelaide Institute for Sleep Health, Nick Antic Laboratory located at 5 Laffer Drive, Bedford Park, South Australia 5042.
- Who is eligible to participate?
- Anyone aged 18 and over.
- In particular, we are seeking interest from those who:
- Live <10 km away from a wind turbine
- Live adjacent to a busy main road
- Live in quiet areas unaffected by environmental noise
- Those who can travel to Adelaide and reside in the laboratory for 7 consecutive nights.
