other bearing-supported devices. Does the sound change when you put in the clutch or shift to neautral (this checks input shaft bearings)? How about with a/c on or off?
Do you hear the noise from the drivers seat, or have you poked around under the hood? It's very unlikely that you're hearing engine knock at idle. If you are careful, you can use a paper towel tube sort of like a stethescope and isolate individual accessory bearings up front.
Out of all that, I'd really suspect the idler pulleys, probably the upper one. Check these soon, they (it) can die catastrophically and leave you stranded.
