check your turbo lines.

same thing happend to me a few years back... during boost it would make this weird noise... moments later, after parked for awhile, I saw a puddle of coolant right under my turbo. After that, I swapped it with new lines... and no more noise.

Does the car still boost normally or is it running sluggishly. If your turbo (or at least the seals) is blown then you would be blowing a lot of white or blue smoke out the tail pipe. The buzzing could be caused by your turbo being lose on the manifold. That would make the gasket buzz a the air rushed by it. Maybe a little more info would help to diagnose the problem.

Check the turbo to manifold bolts, they really like to rattle out.
