Interesting the noise level of same length of 2 different manufactured belts, the US made Gates has a very loud high pitch noisy, the German made Omega noisy too but the high pitch is to a lesser degree. The test was done for both belts at engine 4000 RPM. The offset of the belt drive is 300mm. Next test will be done under propeller load.
