Sounds like a wheel bearing to me. Hunting down which one is a bit tricky. You can try jacking the car up. For the front wheels, try spinning them by hand and see if it feels "crunchy." For the rear wheels, you'll have to run it in gear and listen for it. Just be damn sure you have the front wheels blocked well. If you have a friend who has a lift you can use, that would be the safest. Sometimes they develop some play in the wheel, (but not always) so you can check for any play by wiggling the wheel side to side and up and down.
