loud noise & hearing

e~veryone do know that hearing loud noise for a long time (hours) is irritating. Most people do know that being exposed to loud noise for hours can lower their ability of hearing.

I do find an interesting article on something like this, but i forgot the resource - it state that, open your mouth (not widely) can help stabilise the sound (pressure?) between the outside source & in your body..

i forgot how it goes, somehow.. (darn)
