High or low RPM motor differences?
I'm building a shoe buffer with 12" buffing wheels, and I need the shaft to rotate at about 800 rpm. Induction motors are available at 1725 or 3450 RPM with the same HP specs. Obviously, they would need a gearing ratios (I'm using pulleys and a belt), but would there be a difference between the two in operation? Purely for my own entertainment, I'd like the hum and whine as it comes to life when power is applied, so I'm guessing that the higher RPM might make a better noise.
Any thoughts on differences between them? Would a higher HP make a better noise? The buffers won't be loaded down. Thanks.
(I meant: obviously they will need different gearing ratios)

I'd tend to go for the lower rpm engine as you have to gear it down. Only having to gear it down 2:1 means smaller pulleys, less cost, and a more compact design.
Also it's likely the faster motor will be noisier, and wear out faster as it's doing more revolutions.
