The differences are pretty big, depending where you are coming from. One of the easiest ways to tell the difference is to listen on the "better" equipment for about a month and then go back to the other equipment.
"Exposure to impulse and continuous noise may cause only a temporary hearing loss. If a person regains hearing, the temporary hearing loss is called a temporary threshold shift. The temporary threshold shift largely disappears 16 to 48 hours after exposure to loud noise."

This applies to warming your ears up/down and is a basic representation of the ears adaptation to loud noise. Sometimes you can cause damage and it can go away years later... (for example; if you are at a mixing desk and you overgain the controls and you get a feedback loop, you are likely ot have a damage at that frequency for some time)
Most significant changes will appear in your hearing, but from an audiophile sense you will find that your hearing does improve slightly over the course of several years, not just several days.
I do not believe that you can recover frequencies that have been totally lost.
I should clarify the blind guy quote, I mean they hear, for example, where doorways are by listening ot the echo of their footsteps in a hallway. Not that they dont hear music.
Music is sound, but not noise. Learning about music doesnt let you understand sound from an audiophile perspective because most musicians do not educate themselves in that area.
Ever wonder why so many bands have crap sounding albums despite having millions of dollars?
a. record companies
b. they like the sound

people are pretty hostile on head-fi because of my join date and number of posts even though I offered one of the most realistic and effective options to improve how well you listen.
