Depends on the spatial resolution I suppose, but being neutrally buoyant (like an airship or hot air balloon) would seem to be much harder to to detect, since you are the same average mass as the air you are displacing.

By opening up a business nearby that causes lots of noise, so something like a truck marshalling yard or truck stop would be perfect as you have large moving objects that cause lots of vibrations, making it nearly impossible to filter the noise out well enough.

Failing that, you would want to have your craft look like a heavy truck as much as possible (vibrations should be close to the same period as a common truck suspension, etc) so their denoising algorithms discard you as yet another truck.

Any object the same density as the surrounding medium should be much harder to detect via this method. Submarines and blimps should be safe for a while.
