I have a JetBlack M1 Pro Mag Trainer. I use my road bike on it, with slick tires. However it is still pretty noisy.
What are the ways to reduce noise from a magnetic trainer?
You can get 3'x3' squares of interlocking foam in packages of four that I put under my trainer. I got mine at Canadian Tire and I imagine you'll find them at Home Depot or some similar home supply place.
I found that by using trainer specific tires the noise gets lower (see these for example).
Another thing that usually helps is to put a carpet under the trainer.
Anyway, the major culprit for noise is the trainer itself, so I fear you should buy another model of trainer if, even by using carpet and proper tyres, it's still too much noisy.
