Noise can be measured with special meters: the noise from a commercial sized wind turbine at the nearest noise receptor (such as a HOUSE that is just outside the legally required SETBACK distance from the turbine) will be no more than 38 dB. This volume is similar to a quiet LIBRARY. 44 dB is like the sound of a bird chirping, 60 dB is the sound of a NORMAL conversation, and NEARBY traffic can range from 50-100 dB. Commercial scale wind turbines are quiet: typically quieter than the wind.
