Last night I was cutting some face frame pieces for a bookcase I am building. When I finished cutting them and took off my hearing protection I kept hearing a high pitched squeal (not tinnitus).
I thought that maybe one of the ballast's on my lights was going. I shut the lights off but could still hear it. Then I shut all the power off to the shop. I could still hear it.
Thinking I was going nuts I shut the lights off again and thought the sound went away. I was sure it was a ballast now.
I climbed on top of my saw/workbench so I could get closer to the lights to hear which one it was (here it comes you say). Nothing!
But I can still hear the squealing. I went back to turn all the power off again. Standing in the dark I thought of something. This past weekend I was teaching my brother how to build cabinets. He was using my sound cancelling hearing protection...
I looked over on the saw, found the ear muffs and found that he had left them turned on, microphones facing the saw. They were generating feedback.
It only took about five or six minutes but when I was done I thought it was pretty funny.
