It's not just the audio folks who are confused. I had a sound consultant when I was working on a theater who insisted that I twist the conductors feeding a 200A panel. Other than being virtually impossible to pull, it was also dumb. He finally told me the reason that he wanted the feeder twisted.
It was to reduce the noise in the theater. He knew that twisting the wires in a data cable reduced the noise and figured that twisting the power wires would do the same thing. I guess he figured that 'noise' only had 1 meaning.
It was just my profound professionalism that helped me hold my laughter until AFTER the meeting.
