My left ear is screwed up because I was riding in a single engine piston private plane with a buddy and during takeoff I readjusted the left ear cup of my Bose noise cancelling headset.

Between the engine noise and the Bose headset trying to cancel sound from the entire cockpit, I lost all hearing above 7KHz and have constant tinnitus.

No JP-8 was harmed in the process. Just a few gallons of 100LL.

Noise cancelling headsets are quite evil. Even in a quiet room, they make my ears hurt from the sound pressure level.
