Mark,

Yes, I have this problem too! Any doorbell type of sound will play over and over in my head, perhaps a little different than what you describe, but the same idea. Mine is a similar to an "ear worm" (when a song gets "stuck" in your head).

It can be extremely annoying. How interesting that you experience this as well. Oh the strange things we experience with our PCS!!

Take care,
