Anyone got any good ideas for the reverse problem? I can still hear 20khz at 30 years old, which is the standard switching frequency for most power supplies. Induction cooktops drive me up the wall, I can't stand to be close to one when its on. (And yes, I've recorded the sound, run it through a fft, removed the lower frequencies and it still annoys me) |
