Thanks. I'll be sure to investigate.

The noise doesn't change dramatically with speed. It starts at ~5mph and stays constant.

My deductive reasoning is that:

-If it was related to wheel speed the pitch would change.

-If it was related to door seals the pitch would change (although my passenger door does not sit flush with the body panels fore and aft of it - off by 1/8". Driver's door is perfectly flush)

-If it was related to engine speed the pitch would change during gear change and acceleration.

As it's constant I wonder if it's some sort of pump or belt that once moving stays at a constant speed. Then again, may well be the brakes!
