I have never experienced this sort of noise before. However, I would expect that the list of potential causes from least to worst serious (and expensive) would include the following. Your serpentine belt is loose or cracked and needs to be tensioned or replaced. Your alternator, AC compressor, water pump, or one of the other devices run by the belt has developed a bearing problem and needs replacement. Finally, you may be developing a problem with the engine drive shaft bearings (Hopefully not). You should take it in to a mechanic as soon as possible.
