Our hearing is the best it can be at birth. In the modern world we take on hearing damage from that time on.
Things you wouldn’t think cause damage does. Lawn mowers at about 90db for extended time cause damage. Just being outside with no noises is about 60-70db. The frequencies you are exposed to are the ones that will take a hit on your hearing.
Ever get in a car with someone who works in a steel mill? Their radio is tuned very tinny, all high-end freqs,…because high-end damage has diminished those freqs in their hearing. These booming cars with loud subsonic freqs blasting they are chasing a dragon. They damage their ears with those freqs. Meaning to hear it the same they have to keep turning up those freqs because of damage.
Fact, because females are not usually exposed to things like construction tools hear much better than males. They can hear those high freqs and can hear you whisper to yourself about them. lol. They hear that stuff.
Because I’ve been exposed to all freqs at high volumes !(110db-120db) my hearing has no dips the entire spectrum is burned out, meaning my total volume has diminished equally. Yes I’ve had tinnitus for decades.
The longer the exposure the more damage. 110db fir 45 min, you have damage. Many sound guys get louder and louder to the point of irresponsible to the listener. The band Jackyl was at 122db for 75 min. It was so thumpy loud it made my heart skip beats. I was worried about the structure of the venue, literally.
Its a long subject , but here is a chart

Every 3db increase is the doubling of volume.
