Your hearing won't come back if you damage it. Even if you love a loud, live gig you should consider DB reducing earplugs or earphones. If you hunt, work around loud machinery or attend loud music events then always consider ear protection.
There is hearing protection that means you don't have to lose all the good audio - it just reduces it a few DB - perfect for live concerts where you're sitting in front of the speakers. And there is hearing protection where you do need to block out the noise, often completely. This is perfect for hunt, gunfire and working in construction or places where loud machinery is used constantly.
