I've got bad hearing in my left ear which I attribute to the pickup I drove when a young man. It was a 1964 Chevy, and the rubber gaskets around the window panes in the doors were totally shot. I had cut holes and installed speakers in the lower portion of the doors. The speaker in the driver's door caused that window pane to vibrate in my left ear.
