The test was conducted by AP Mechanical Engineering in Varde in Denmark, by Preben Kristensen, who states:
"The conclusion is that there is no doubt about that RVS Technology has very positive effect to the noise and I will add RVS at each oil change."
The noise level of the wind turbine gearbox dropped from 97.2 dB to 85.3 dB after RVS Technology treatment, which in practice means that the noise level has more than halved.
