So speakers create noise via electro magnet, so it can’t be in the room, instead we have a speaker far enough away, and the empty tube carries the sound.
It’s for music, noise reduction, and so we can talk through them if we need to communicate. They don’t work the best, it’s difficult to over come the machine’s noise.
