Ok so lets say i properly fit an earplug that is 33 db.. Which i always do and there never sticking out and im out somewhere thats 95 db.. Will that bring it down to 67db or no?
If you...
1) wear new earplugs
2) fit them correctly as per these guidelines I have provided previously (see again below); especially step #3
3) do not move about after having inserted the earplugs
...then you will get very close to the protection offered by the manufacturer of the earplugs at the various frequencies. Yes!
But as a example - when I go to the gym - I probably have to reinsert my earplugs every 15 minutes or so in order to get the maximum protection (because they come undone). Which I of course cannot be "bothered" to do. Because I am human (believe it or not). And so the protection level goes down.
And be honest here: after you insert your earplugs, do you press and hold the earplugs in for about one minute to let them expand correctly? I am pretty sure many people overlook that step - either because they don't know about it or because "oh well, it probably doesn't matter"-mentality. And leaving out that step immediately takes away 10db of protection (round figure, of course).
And do you always use new earplugs? And when attending an AC/DC concert, do you stand absolutely still, or do move about together with the rest of the crowd?
That's why the derating calculation has been made. Folks - I didn't invent the calculation; it was invented for a reason. Because there are ideal conditions... and then there is reality. And reality is that people do end up with tinnitus after going to concerts - sometimes even with earplugs as some members on this board can attest to.
I am leaving this thread now.
