sound waves can be fatal at high levels or if not that extremely disorienting and will lead to permanent deafness. this would be a brilliant battlefield tactic but in order for a bomb like this to have the desired effect of destruction (and more than likely some widespread debilitation) you would need to pack a B-52's bay with as many flashbangs as you can and drop them all on the same spot, i cant wait to see what the U.S. has in store for this project.
