I do not destroy hearing, just have a very painful voice,and when I want to i can get VERY LOUD, so they run away to avoid the pain.
rearding the very loud, about 25 years ago I obtained an analog sound level meter, set in on the highest sound range 1 meter from me in DEEP bush and yelled at about 80% of max volume, the needle on the sound level meter afterwards was bent.
