It would be difficult to know where the noise coming from without checking the vehicle.

The following are some of the possible causes of noise:

a) Defective or uneven wear tyre
b) Exhaust system leaking
c) Defective wheel bearing
d) Defective drive shaft's CV joint
e) Defective transmission bearing
f) Defective fan belt's pulley bearing
g) Defective air pimp (if equipped)

It is advisable to send your car to a workshop and conduct a road test together with the service advisor so that he could help you to identify where the noise is coming from.
