Basically the idea is based off the… forget the words, but something in the ear canal. It gets damaged by loud noises, and since it appears ones closer to the edge process higher frequencies; we lose those first.
So older people should have less. It’s not always that way in practice though. Some older people didn’t listen to loud music, never went to concerts, etc, and have less damage. When I was 30 or so, I worked with some 18 yesr olds and 40 year olds, and we tested. The young ones could hear well into 20k+, while the 40 year old was pretty bad at 8k or so. I personally could hear 16k or so and feel 17-18k.

Yup. I’m in my 40s and can still hear 17k+ quite well.
