why does playing 3 different TV’s/media devices, all synced playing the same thing, sound like 3 “layers” of sound instead combining into one sound?

Question

Is it because they aren’t TRULY synchronized? Because the different quality of speakers don’t make perfect sounds waves that can line up/combine/harmonize?

Are there any instances these sounds WOULD combine, like with some kind of program or piece of hardware? How is this different than something like a concert where you can’t perceive the individual speakers?

(I have a decent understanding rudimentary physics/sound and a good understanding hearing/the vestibular system/cranial nerves btw! Im not actually 5 haha)

Answer 1

In a perfect world the sound is recorded in the same acoustic environment it will be played in. Aka, one microphone to record for each speaker to play.
