Was the noise present prior to replacement of the parts concerned?

Try removing the belts and running the engine briefly to eliminate the possibilities of the noise being one of the driven components.

The alternator, compressor and power steering pump can emit humming noises. Recheck the belt tension. Overtensioning the belts can result in humming noises.
