Learned that at a safety program...
Hearing loss occurs when your ears are exposed to........
85Db for 8 hours.....................Here is the interesting part
for every 3 Db increase above 85 your exposure time is cut in half
therefore at 88 Db hearing loss will occur at 4 hours
at 91 Db only 2 hours
at 94.... 1 hour ( Chainsaws run around 94Db B.T.W)
You get the idea.
Also it was said that by the time you notice that you have lost some hearing aproximately 1/3 of your hearing has been lost forever........
WE all no this I thought it was interesting
