It is important to note that the device is unlikely to be used on the battlefield anytime soon and will probably be used as a form of crowd control.Naval Surface Warfare, Crane Division, a Navy research, and development facility in Indiana that develops handheld and crew-served weapons for the service. is very interesting indeed.
AHAD works by using a series of directional microphones and speakers that can target a speaker's voice. The speech is then recorded and transmitted back in the same direction. The behavior of the target will be noticeably altered by the action, likely also confusing anyone who was listening to the target person. Put another way, such a weapon will make you think you're going crazy -- so too the people around you. Such a technique will likely be most effective when the repeating speech is a syllable or two behind the real-time speech of the target speaker.
