Hi OP - I have heard this too in mine. Almost sounds like something is broken or loose. Only occurs above a certain speed (but I haven't done any specific tests - just ah that's weird, and if I'm going slow, no sound). I would say I'm going an appropriate speed for speed humps, certainly under the 25 mph limit.
