       @q3k you mean the short constat-frequency-ish whine before the motors start ramping up?

       @wolf480pl @q3k The whole acceleration sequence? I think EV makers are missing a trick by not allowing a bit more of those sorts of sounds. I had occasion to drive my old civic hybrid a bit with the back seat removed and the inverter sings its own little song as you drive .. normally inaudible behind 3” of foam seat cushion.

       @acsawdey @q3k oh, so all of that sounds is made by the inverter and not the motor itself?

       @wolf480pl @q3k I am not familiar with this train but generally it’s kind of both? The inverter is conducting the orchestra by generating a multiphase waveform to drive the motor .. some components in both are coupling a little of that energy to audio.
