Summary: 

This video of the Suncor wind farm in Ripley Ontario was recorded using a personal video recorder. Given the difficulties of capturing noise using consumer video products, Windaction.org consulted with two individuals with experience with wind turbine noise: Rene Taylor of McLean County, IL and Richard James of E-Coustic Solutions (Okemos, MI). Ms. Taylor lives within 1500 of Horizon Wind's Twin Grove wind energy facility. Their comments are important to consider when listening to the video.

Rene Taylor: "I viewed the Canadian video last night and feel this is a true representation of turbine sound.  I have taken many videos with similar sound and am always frustrated because it comes out much softer than what we actually hear.  I'm sure this is the case with this video as well."

Richard James: The video appears to pick up the audible sound of the wind turbines. The problem with recordings taken with consumer products (other than lack of calibration) is that microphones do not handle low frequency sounds and thus the recording lacks that omnipresence that real wind turbines produce. The microphones on consumer video products are biased toward capturing human voices. It is clear that the Ontario audio is missing much of the low frequency content from about 250 Hz down. It is the lower frequency sounds of the turbines that penetrate homes and vibrate buildings.
