Does this noise come from the engine bay ?, does it make this noise while the car is stationary, moving or both ?. If it is coming from the engine bay ( and it makes the noise while the car is stationary ) then open the bonnet and get someone to rev the car while you listen to where the noise is coming from.

waterpump/alternator/timing tensioner//alternator belt/auxilary belt...could be any of these..
One of the tricks is to have the engine running and squirt each component above with WD40 and hopefully the noise should go (no guarantees). This isnt a fix for something that needs replacing though its just to identify the noisy part.
