Noisy bit main power supply

Hello,
Just wondering if anyone has had any issues with noise generation with their bitmain 1800w power supply. I did go with two mini doge/lite coin miners because they are quiet. But was surprised at the noise generated by the power supply ( roughly 60db at about 2 feet away with
my iPhone dB meter). I tried to up load a quick video clip but it was not permitted.

Thank you
Colin
