Three phyphoxphones and superposition

By the way I did not use the toilet rolles, I used a tube. The tube length is limited by the distance between the headphones.

Two phones on 440 Hz sounds perfectly in tune to me. If the frequency would differ the slightest I think you would hear it, no? If you listen to 440 Hz from one and 441 Hz from the other you clearly hear a 1 Hz "pulse" (or "beat") from the interference. But volumes could differ of course!
