Yours sounds like a something which vibrates at a certain frequency rubbing against the car body or chassis. If I were to guess, I might think it was an exhaust mounting, or a loose ac blower. Maybe check and tighten all the screws/bolts in the vicinity the buzzing is coming from. Check engine/tranny mounts too.

the noise started right after i had the ac compressor and receiver drier replaced in my car
i took off the plenum and put it back on just in case something was loose there
didn't make any difference
i need to have the shop that did the work take a look at it... but the noise doesn't happen until the car has been sufficiently driven around
i'll get around to dropping off the car
