Well, I guess it's time for me to make some noise, here...I've been really careful with my hearing for my adolescent and adult life, and it's really paid off...I can still hear stuff that my kids lost the ability to hear years ago. Of course, I started out with excellent hearing on a wide range; TV used to drive me nuts because I could hear the drive coils in the back and it HURT! Fluorescent lights kinda bothered me, and right now my hard drive is a little unpleasant (it rotates at 7200 rpm...I don't know what the pitch of the sound is). I listen to orchestral music and can still hear most of it; I notice that as I get older (I'm 63), I kinda want more "tweet" from my speakers, and less "boom".
I use Pro-Ears electronics, and they're great, EXCEPT that 1) I can't wear a hat (yeah, I know what they tell you, but I can't), 2) my ears sweat like crazy in there. I can crank up the volume and hear guys talking 100 yards away, but muzzle blast doesn't bother me.
I would like to try the new "Woodland Whisper 2" thingies...they go into your ear and supposedly work like muffs, and two of 'em cost about 100 bux. I've been looking for more data on 'em but I can't seem to find any. Any info gratefully received....
