When I was a kid, the whine of CRTs was genuinely annoying, and those 'keep pests away' things hurt when they went off. I was looking forward to not having to experience that as I got older.
Now that I'm middle-aged, I can tell there's a little loss around the vocal frequencies... but damn if those old tubes and pest devices aren't as annoying as ever. Ears are weird.
I had a magic skill when I was in high school: I could walk into any computer lab and tell you exactly which monitors were on (when the computer was off). I believe this is around 15K.
it looks my hearing drops off between 13k (noticeably quiet compared to 12k) to 14k (can't hear it at all).
Hah reminded me of when I was a kid walking into the living room with a few people around many times and turning off the TV (crt of course) that was just showing a black screen. It was so loud and obvious to me. Now all the TVs seem to have bizarre screensavers
I also seem to have beyond normal hearing, and can hear some electrical devices or high pitched sounds where others don't seem to.
Last year I was in a mall where they had a Tesla store and it was emitting a horrible high pitched sound.
Where I live some houses have Seagull scaring devices and they also emit a horrible high pitched squeal which I'm guessing others can't hear, otherwise it would honestly drive you nuts.
Not so sure about that, mixing engineers have to do very precise manipulation of sound and there’s plenty of them working well into their 40ies and beyond. While of course aspects of your hearing deteriorate, it should still be pretty simple to pick out the artefacts of compressed audio if you’ve gotten attuned to them at a younger age… At least for heavier compression, something like a 320kbps MP3 or 256 AAC is hard to distinguish from lossless but that’s also true for young folks.
The positive is that you can just embrace the convenience of 'good enough' compressed audio and wireless headphones.
