Raise your hand if you wear glasses so you can see 20/20.
Raise your hand if you have corrective hearing devices that normalize the environmental damage and adjust hearing parameters according to your effective 'listening' age.
So even since Ben Franklin we've been able to smooth out differences in vision. Now, other than 'hearing aids' the same does not exist for hearing and there is no 'standard' other than hearing 'beep' 'beep' at difference frequencies, which is not the same as hearing music or reading a street sign at 40 feet. The only true benchmark we have is getting a 12-year old to listen to something and we deduce what we missed by them describing what they heard.
How many still cling to their black box faux wood grain 27" CRT's playing S-VHS? That's analog.
But how many think our 4K TVs are actually showing 4K...or even HD...it's digital anyway....but it's okay for vision....I just ignore the sloppy compression and carry a film projector with me just in case.
