TITLE: Development of Analysis Methodologies to Determine Contribution of Indoor Wind Turbine Noise on Local Residents
Abstract
Wind Turbine Farms are found in many regions of Canada, including Ontario and are a source of clean renewable energy. For some residents living near wind turbines, the benefit of clean energy is offset by the impacts from the environmental noise that is generated by the wind turbines. To investigate the human impacts from wind turbine noise, it is important to have noise data representative of inside the residence. This leads to several challenges including the determination of the contributions of the measured noise from the wind turbine and those associated with other sources, both indoor and out. This must include the infrasound component from the turbine which is below the typical frequency range of human perception but may contribute to adverse impacts to people. This research will use wind turbine noise data that has been collected inside and outside of residences to develop a methodology to determine the indoor noise contribution, absent of other sources. Techniques used in, for example automotive acoustics, are investigated. These include cross-spectral density function, cross-correlation, coherence, and selective noise source contribution. A post-processing algorithm to extract and identify the indoor noise contributions from nearby turbines only, will be developed and tested using 1680 hours of measured wind turbine noise data. This will facilitate future studies on indoor noise impacts, including human health and annoyance studies from wind turbine noise without the obtrusions of other environmental noise contributions.
