Michelle, this could be as simple as a small pebble stuck in between your rotor and the metal dust shield. Happens to me a few times a year with my Trailblazer. If you can video the sound and post here. I'll tell ya if it's the shield or not.

The bearing hub is going out. Your family mechanic can replace the $110 part in an hour or so if he has a standard toolkit and a 35mm deepwell socket. They tend to give advance notice. The heatshield vibration is it.
