I mean, TV. Kids were definitely a market for it, throughout its history, but until the flat panel era nobody cared that the flyback transformer in most CRTs made a deafening whine in the 20khz range. I could walk into a house and hear a soundless TV three rooms away, and I know I wasn’t alone in that.

Not quite that high. Around 15KHz. (15,734 Hz for NTSC, 15,625 Hz for PAL.)

Yeah I could too(not know though...). Trying to sleep, and knowing your parents are watching TV in the living room few doors away isn't the best experience.

That’s what that was? I had no idea. I just knew I could hear muted TVs whine. I asked my parents about it. They couldn’t hear it. So I wasn’t sure if it was real.

I feel so relieved.
