long ago, when men were men and giants walked the earth, i could hear multiple conversations in multiple languages in a crowded room. at your age, there's no reason you can't do the same. now, i'm lucky to hear the TV (not that that's necessarily a bad thing, anyway). classic high frequency hearing loss, caused by
1) shooting without plugs when i was younger
2) fooling around in tanks when i was younger
3) foolong around with REALLY BIG (105mm tank cannon) GUNS when i was younger
3a) fooling around with slightly smaller (50 cal M2) machine guns when i was younger
4) fooling around with high frequency, high intensity jet and turboprop engines (C-130 and C-141) when i was younger and jumping out of airplanes for a living
5) age (i'm now fifty two)
6) (maybe) genitics: my father was nearly stone deaf when he died at the age of sixty eight, and my mother was too mean to admit that she couldn't hear and didn't care
so, don't do as i did. most helicopter pilots i knew wore both the helmet (which has muffs built in) and earplugs. i would recommend you do the same.
earplugs are much more comfortable now than they were twenty years ago- get a bunch of the foam expandable ones. i wear them at work, twelve hour shifts, with no discomfort. i also wear muffs, especially when it's cold. you can get muffs with all manner of bells and whistles, check out the ones that automatically clip out the sudden high volume noises but let normal conversation through.
what? say again?
