When i started being a union carpenter many years ago, it was against union rules to wear ear protection because you were deemed to be Unsafe from not hearing a yelled warning, (it was actually because the oldtimers thought you were a pansy to need them) so after many months of nailing baseboards in empty apartments with a pnuematic nailer I was getting ringing in the ears every night. After a trip to the doctor, I was given Dr. orders to wear ear protection and given drops which helped greatly. Tinninitus (sp) is caused by echos in your head which would not happen if you had not destroyed the tiny hairs which used to deaden those echos.
Forcing all people around to wear ear muffs or plugs is big. I have noticed that not all loads make the same sound, or generate the same SPL. I recently switched to Inter. clays for my shot gun powder because it is significantly less loud than other powders, do not konw how but it is. stand behind a trap range and listen to the various guys shooting and you may hear as i did one guy who is a good bit quieter than the others then ask him for his load data. I have also found that titegroup is less loud in my 45 too.
The navy now has a pill that supposedly reduces the impactof noise on the human ear.
