3. One of the negative impacts of wind turbines is the noise of the spinning turbine.
Near the blades of the turbine, the noise level is similar to that of a lawn mower.
Farther away, at around 400 meters from the turbine, the noise level is similar to that
of a refrigerator. As a result, wind turbines cannot be put closer than 300 meters to
the nearest house in some areas. How does this requirement affect the use of wind
farms in areas where people live close together?
