    Idk if it’s just me but I have pretty good hearing, so I can hear the high pitch tone CRTs make and it drives me crazy.

      This only happens with TVs or very low quality monitors. The flyback transformer vibrates at a frequency of ~15.7k Hz which is audible to the human ear. However, most PC CRT monitors have a flyback transformer that vibrates at ~32k Hz, which is beyond the human hearing range. So if you are hearing the high frequency noise some CRTs make, it is most likely not coming from a PC monitor.

      Its a sound thats a part of the experience, and your brain tunes it out pretty quickly after repeated exposure to it. If the TV is playing sound such as game audio or music it becomes almost undetectable. Unless there is a problem with the flyback transformer circuit, which causes the volume to be higher than its supposed to be.

        Oh neat, thanks for the explanation! That makes sense as most of my crt exposure for the past 10 years has been classroom TVs and museum exhibits.
