I do not know what type of noise that is but if sounds like belts slipping, then behind the steering wheels is the alternator. I still suspect the belts.
Does the noise happen only during acceleration and how long does it last?
A slipping belt sometimes will not show during free reving. Try driving with AC and all electrical loads off and then again with AC and headlights plus other electrical loads on and see if there are any differences.
If the belt multiple ribs are worn, they are not providing a good grip on the grooves.
Try twisting the belt at its longest part and if the resistance is low, the tension of the belt is not enough.
