Once you have it, regardless of it's cause, all the hearing protection in the world ain't gonna make a difference...........The guy is asking for a REMEDY..not a rebuke...........
Now see I found that to be 100% wrong. Over a few months of wearing hearing protection for every loud noise, the ringing does get better. Might even take years--its been 20 years for me, maybe it took a few years before it really helped. I just know for me hearing protection does still help me. I'm 47, btw
