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?
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.
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.
