Wind noise? Levitation magnets commutating at audible
frequencies when time-over-target is short enough?
Everything makes noise when you go fast, pretty much.

I saw a tv segment where an airplane glided overhead at low altitude, with no engines on. It still made noise like a jet, simply by moving through the air at high speed.

Some maglev rails have gaps between them.. they can be the cause of the sound.
