Summary(Plain Language Summary, not published)
Manuscript discusses data collection, processing and analysis of seismic waveform data collected between May 2013 to May 2014 during an interdepartmental study lead by Health Canada to study noise generated by a modern wind turbine power facility near Summerside, PEI. Data analysis shows that four monitoring stations (located up to 10km from the facility) were able to record the turbine-generated noise. The turbine seismic noise generated is determined to be associated with the vibrational modes of the tower and harmonics of the spinning blades as they pass by the tower superstructure. These vibrations are likely transferred to the ground through the foundation. Models of noise growth with increasing wind, and attenuation with distance are constructed. Calculations of turbine contribution to the natural seismic background, and comparisons to a regional earthquake, are made. It is concluded that turbine seismic noise from the facility is not likely to be felt by the local population.
