It it was that loud then I'd expect something was wrong with it. I can no longer hear those frequencies, but I could when I was a kid, and I don't remember it being annoying at all. Just one of those things you only really notice after it stops, like when the fridge stops humming. Our cat also didn't react at all from my memory
- EvanAnderson 3y agoI tried to show off an Apple II to my then 5 y/o daughter using a CRT monitor. She the sound (presumably somewhere around 15Khz) and was really annoyed by it and clasped her hands to her ears. My wife and I were completely oblivious. We didn't see if she could acclimate to it. The monitor works okay but it's early 1990s stock so, presumably, something might be wrong w/ it, too. I definitely remember hearing CRTs as a kid and adults telling me I was making it up.
- vikingerik 3y agoThe horizontal refresh rate (scanlines per second, how often the beam retraces horizontally) of NTSC video is indeed 15750 Hz, and PAL is 15625. Just about every CRT will emit some amount of audio at that frequency, and yes that's just at the upper end of the audible range for some (mostly young) humans.
- colanderman 3y agoMy family's Apple //e monitor has always emitted a high pitched whine, since I was a kid. (I can't hear it anymore but my niece tells me otherwise.) What worked for us has always been to wedge a folded up piece of paper underneath the bezel of the screen. Don't know why this stopped the sound but it does.
