Some kind of "Gun Like" device that, when pointed at an object, say a wall of wood, and you activate the device, it "hits" the wall of wood with some kind of concentrated wave of energy, and a bang! is heard from the wall directly where the device was pointed (It is not touching the wall). Or, I point the device at a glass, pull the trigger, and a ringing sound emanates from the glass, like it's been "Hit." Would a device that shot out concentrated, compressed sound waves work like this? Thanks for any replies.
