Help a nerd who doesn't get out much, Pt. 2

I enjoyed the concert, though it was very loud and the acoustics were terrible.

Twelve hours and a solid sleep later, my ears are still ringing, and I have a physical sensation of cotton lodged into both of them. Is this... should I be worried? I don't know.

A friend who goes to many concerts tells me that, doy, they sell earplugs at the bar, you know, and everyone who isn't dumb wears them. I didn't know this. I don't know anything!! I am a nerd who doesn't get out much.

Seriously though, I'm starting to get a little concerned about this.

Subway trains are about 100 dBA (decibels weighted to human ear response). Concerts (rear seats) are 110 dBA, which thanks to the logarithmic goodness of decibels comes out to a factor of two higher.

Assume train noise lasts 5 seconds. So if you take the train twice a day, 250 days a year, you'll accumulate 20 minutes of exposure time at an intensity half that of a concert. 40 minutes if it lasts 10 seconds, assuming that that full 10 seconds is at the peak intensity, which it isn't.

It's worth protecting yourself against high environmental levels. But given the considerably greater hazard of concerts there is nothing inconsistent about protecting against concerts even if you don't worry about trains.
