When I was a kid I noticed that the adults in my life couldn't hear that CRT sound. My son bought a CRT TV with a built in VCR to use with a Nintendo 64 to get out the last frame of latency. I noticed the other day that I can still hear that sound, but I've always had sensitive hearing and I've always kept amplified sound at a low level and worn ear protection while using machinery, going to motorsports events, etc.
(In the past I have volunteered as a sound man for live music events but I have never been at a venue which I thought wasn't too loud in terms of absolute sound pressure or in terms of there being audible distortion in the amplifiers & speakers, so I haven't made a habit of it. My son won tickets to a 38 Special + Foghat show that we went to last week, I didn't mind the loudness much but it was clear to me they were pushing the sound system just a little too hard.)
