I've been in radio for 33 years. I saved my ears by never wearing headphones at work.
Recently went back on the air, so now I have to wear them...but only three times an hour for four hours a week.
I've been a mobile DJ about as long, and I've worked for a concert production company for more than 10-years.
I look silly, but I always stuck my fingers in my ears when going near the speakers.
and, yes Handinon, I've been prescribed a fair share of NSAID's over the years.
I do have some "white noise" in the background...but I have fared pretty well...all points considered.
(I will admit to "selective hearing"...when in the company of certain people)
