    You can’t hear it much out of your 20’s unless you’re an edge-case-human. The frequencies in question that you’re referring to are ones that almost all humans are deaf to by the time they’re 30.

      CRTs whine at ~15kHz, which should be audible until at least your 40s.

      I’m 37, and have absolutely destroyed my hearing by always having a loud sound system with booming subs in my car ever since I was a teenager, yet I can still hear up to ~17kHz. I can always tell when I’m in a house with a running CRT.

      If you’re younger than me and can’t hear CRTs, can’t tell the difference between FM and HD Radio, or the difference between a 96kbps MP3 and 320k/lossless, then it might be a good idea to get a hearing test.
