How many meters are the blades of the wind turbine generator
The average blade length of a typical onshore wind turbine is about 165 feet (50 meters), but there is a trend towards taller turbines, particularly offshore, where blades can span up to 260-290 feet (80-90 meters). Wind turbine blade technology has evolved dramatically over the. [PDF Version]
How loud is the wind noise from wind turbines
Modern wind turbines typically generate noise levels between 43 and 45 decibels (dB (A)) at a distance of 350 meters, a sound level often compared to a quiet refrigerator, significantly lower than common concerns suggest. [PDF Version]FAQs about How loud is the wind noise from wind turbines
Why do wind turbines make so much noise?
The noise from a wind turbine comes from two sources. The blades create a whooshing sound as they cut through the air, and there may also be a less.
