Narrative:

After takeoff; there was a vibration/noise issue around the nose gear after retraction. Suspected that one of the doors was not closing properly. Ran through the quick reference handbook; cycled gear but no help. Decided to declare an emergency and return to departure airport. Extension was normal. First officer was flying; but decided I should do the landing. During the process of swapping aircraft control back and forth a couple of times to facilitate communicating with ATC; flight attendants; maintenance; etc; we each thought the other had declared an emergency as ATC gave us expedited handling. Not sure if we actually did so or not; but returned for an uneventful landing. Landing was overweight at 140;000 pounds. Smooth touchdown at around 300 FPM or less sink and didn't apply brakes until well below 80 KTS. Gentle braking was then applied and returned to gate. Maintenance inspected; changed both nose tires; and found no discrepancies noted for the overweight landing.
