I really should get some ear protection. Thing is though that I seem to have a mild form of tinnitus which i've had pretty much as far back as i can remember, i think it's because as a young child (maybe some would argue i'm still a child now, but that's a different story altogether) i had very sensitive hearing, i couldn't even go to the cinema or anything. I think i have a bit of hyperacusis now aswell, for the last couple of nights i've been having trouble sleeping because of the ringing in my ears even though it's very mild and it's pretty much the same as the previous nights. I just can't switch off because my brain keeps trying to switch me back on, if that makes sense. So thanks ian for giving me that link, if it ruins my holiday i'm definetly seeing the doctor about it.
Also when you consider that 100db is like a loud rock gig and 75 is like the sound your car probably makes traveling along the motorway, that 25 db of protection really does begin to make sense.
