I assume that means they make less than 60dB as I was measuring an ambient 60ish dB in my garage. Running timing pulleys, which create some noise themselves, I was measuring ~85dB at 3500 RPM. With a good pulley set I think that will be down to 80dB but I won't know until I have them. I'm pretty sure this is the largest source of noise at this point but it seems like even two people with the same setup on different machines can even have a large difference in noise.
