Common problem, easy solution, three possibilities only. Either, the Power Steering fluid is low or one of the belts at the engine need to be replaced or the power steering pump is worn and needs to be replaced. Check to see how much fluid is in the power steering pump, if full then replace every belt on the engine, if the sound goes away then you are done, if not replace the power steering pump.

Possibly a bad wheel bearing.
The whistling sound made by your car could be caused from brake dust. Another reason may be from a bad wheel bearing that needs to be replaced.
vacuum leak
The most likely cause of the whistling noise is loose or worn weather stripping around the door. If this is the case, the sound heard is the wind.
