I damaged the hearing in my right ear when I was 8, and then again when I
was in high school. At 8 I mistakenly discharged a pistol indoors. After
that incident I had recurring tinnitus that will still occasionally surface
these days.

In high school I ran a DJ dance company and was the DJ. Week after week I
worked the turntables next to a very loud speaker that acted as a monitor
of what was going over the main speakers. It wasn't until I applied to the
US Air Force a few years later that I discovered a 40% loss of hearing in
the right ear.
