I model in HO, but at one train show where the modular club was set up a guy had a portable 4x8 N-scale layout with a large stereo mounted underneath. He had sound and on a small layout, you don't really notice that the sound doesn't travel with the train. The only problem with his solution as far as I was concerned was that there was no attempt to "scale" the sound. In the hall it sounded like a full sized train was going through the hall! I think a sound decoder driving decent speakers mounted under the bench work would allow you to have N-scale with sound.
