  Check Engine oil, its maybe the oil that lack or dirty that needs to be replaced. Check your Engine mounts as well.

  Ok! then it must be a serious problem probably. Check your Belt and Pulleys. While engine is on, try to open the hood and observe for the noise, ( base on what you said, the noise can be heard even at a stop position) It could be a damage Belt and Pulleys. Check the engine mounts as well to know that it is not the one causing the noise. It's easy to recognize if the mount is worn or damaged.
