As that's what I've been trying to do. When I'm driving, the db can be anywhere from 80-90db which worries me! However, doing some research on the guidelines, shouldn't we just try to stick by those? For example: 85db - 8 hours 88db - 4 hours 91db - 2 hours 94db 1 hour 97db - 30 mins etc. Or do we have to take extra care with our ears. Mine is from a concert mixed with anti-biotics. It's probably very dependent on the person, but I can't seem to put a finger on what makes mine spike. At the moment it's horrible and I really hope it goes back down again. Every time it spikes I just worry which makes it worse!
