Today, an operating wind energy project
at a distance of 750 to 1,000 feet emits
sounds at a level comparable to a kitchen
refrigerator or a moderately quiet room.
Wind turbines make a whooshing sound as
the blades travel through the air. When
you are directly under a wind turbine, you
may hear a hum made by the generator and/or
gearbox. Because wind turbines only produce
sound when it is windy, and the wind makes
sound as well, you usually can’t hear
an operating wind turbine from more than
800 to 900 feet away. With appropriate setbacks,
wind turbine sound emissions should not
affect neighboring residents.
