i know there are speakers in the works where you'd have a tiny box that would actually project the sound in all directions effectively turning the wall themselves into giant speakers
I've heard about this, and did you know that a device has been made to "shoot" sound? The army uses it for training by sending certain sounds to parts of their training course using a pulse. It shoots the sound at an unaudible rate and after the sound hits a surface it becomes hearable. quite amazing! :shock:
