Very annoying issue on Class 800 trains - when the train is accelerating using the electric motor, my hearing aids produce a rapid pulsing squeal. If I take them out, there's zero sound for everyone else - it is EM induction from the motors producing it directly in the hearing aids.
To put the sound on a scale - when it can be heard, it drowns out all other sound.
So, I'm guessing the trains and the motors don't have great EM shielding.
