How Loud Are Wind Turbines? (2024) | Today''s Homeowner

Yet, the loudness of a turbine is still up for debate. Standing under a wind turbine will expose you to sound levels around 100 decibels, but the noise levels quickly drop as you move away from the turbine. At a distance of a few hundred meters, the noise from the turbine is no louder than the ambient noise level.
