ENESSERE Hercules Wind Generator is virtually silent and with minimal vibration. The rotation speed for which it may trigger phenomena of noise emission, the background noise of the wind far exceeds the noise emitted by wind turbine in motion. The noise emitted at 250 rpm that is at its maximum speed of rotation, is 38 dB and if we consider the intensity of noise that is annoying to the human ear is 60 dB, we can assume that the wind turbine of ENESSERE is technically not audible.
