Having lost most of my hi-freq hearing and some of the normal voice range and both aggravated by a roaring case of Tinnitus.....do everything you can to protect your hearing. Be aggressive in taking what preventative measures you can.
Almost two thousand hours of Chinook time before the days of good helmets and earphones got me early on.
If you find yourself running out of volume control on the interphone panel....you just might want to have a really good hearing test done. You will probably find the Hi-Freq range is suffering a loss.
At least now I have a good excuse for ignoring the Missus!
