That can very well be a bad wheel bearing. One way to see is to jack up the vehicle and listen to the back of the hubs with a stethoscope, (or a long pipe) while the wheels are turning, (with engine running).

.

Another is to see if the sound changes when you turn into and away from it. A bad bearing on the right side, (front) will be louder when turned to the left, (while moving) and subside when turned to the right. Visa versa for the left side.

.

If so then the (left front) wheel bearings would have to be replaced.
