I have drop ceiling in my room and get some pretty annoying buzzing at select frequencies. Has anyone else addressed this issue that could share some insight or your thoughts?

Does it sound like the framework is buzzing, ie metal on metal?

hmm I have a drop ceiling with all the joists filled with acoustic insulations down to within an inch of the tiles and have never experianced this. i wonder if it is the grid as Adrian suggested or maybe a tile that is out of place? My tiles are the drop down ones so they do not move but man that would have to be some frequency to move or shake a tile/grid. I could see the lows maybe doing it.

later

Run some test tones and find out where the vibrations are that cause the buzzing and either shim the two surfaces with cardboard or you can also tape the seam ... the back of my TV has about 10 little pieces of cardboard shoved into some of the various panel seams that were vibrating.

Metallic A/C ducting tape works great in hidden areas, plyable caulking also works well.

I have been able to track it down when its buzzing and it seems to be the tracking mounted to the wall mostly and perhaps where the tracking meets each other.

I wonder if caulking the joints with some latex/silicone would help?

I'd probably get a tube of a good pliable caulking and try to run a thin bead of caulk along the seams maybe.
