Today I got exposed to a firetruck driving through the road while I was in a parking lot outside my car with no hearing protection. I was about 24-25 meters (around 80 feet) away from the fire truck and I was exposed to the firetruck siren for a few seconds while I tried to plug my ears with my fingers.
My ears kind of hurt hours later. I might have some very faint ringing.
I just want to know how loud are those darn firetrucks and if I have any permanent hearing damage?
