WHY DOES THE CAR MAKE WHISTLING SOUND WHILE MOVING

My car has been making whistling sound since I bought it. The sound is always there no matter at what speed I drive, the sound is there at 40 km/h and stays all the way and over 120 km/h. But it goes away for a while when I hit the brakes and then there is another whistling sound which I am sure of comes from the front brake pads contact with the drum. But I want to know where is the first sound coming from?
If the sound changes when you apply the brakes, that can also be from the pad wear indicators. Very often the pads twist a little when there's no pressure to hold them straight, and that's when the "squeaker" hits the rotor. When you apply the brakes, the pads straighten out and the squeaker can move away from the rotor.
