Imagine a weapon that creates sound that only you can hear. Science fiction? No, this is one area that has a very solid basis in reality. The Air Force has experimented with microwaves that create sounds in people’s head (which they’ve called a possible psychological warfare tool), and American Technologies can “beam” sounds to specific targets with their patented HyperSound (and yes, I’ve heard/seen them demonstrate the speakers, and they are shockingly effective).

Sound Now the Defense Advanced Research Projects Agency is jumping on the bandwagon with their new “Sonic Projector” program:
The goal of the Sonic Projector program is to provide Special Forces with a method of surreptitious audio communication at distances over 1 km. Sonic Projector technology is based on the non-linear interaction of sound in air translating an ultrasonic signal into audible sound. The Sonic Projector will be designed to be a man-deployable system, using high power acoustic transducer technology and signal processing algorithms which result in no, or unintelligible, sound everywhere but at the intended target. The Sonic Projector system could be used to conceal communications for special operations forces and hostage rescue missions, and to disrupt enemy activities.
Here’s the question of the day: if the military were to beam voices into somebody’s head, what would they say?
The Army’s very strange webpage on “Voice-to-Skull” weapons has been removed. It was strange it was there, and it’s even stranger it’s gone. If you Google it, you’ll see the entry for “Voice-to-Skull device,” but, if you click on the website, the link is dead.
The entry, still available on the Federation of American Scientists‘ website reads:
Nonlethal weapon which includes (1) a neuro-electromagnetic device which uses microwave transmission of sound into the skull of persons or animals by way of pulse-modulated microwave radiation; and (2) a silent sound device which can transmit sound into the skull of person or animals. NOTE: The sound modulation may be voice or audio subliminal messages. One application of V2K is use as an electronic scarecrow to frighten birds in the vicinity of airports.
The U.K.-based group Christians Against Mental Slavery first noted the change (they also have a permanent screenshot of the page). A representative of the group tells me they contacted the Webmaster, who would only tell them the entry was “permanently removed.”
The image above is one person’s self-styled depiction of how a “voice-to-skull” weapon might work.

Wattre’s technology, called Hyperspike, is a Guinness Book of World Records winner for “loudest speaker.” As for the laser portion, produced by a company called Stellar Photonics, DANGER ROOM’s David Hambling actually has a good writeup of the technology at New Scientist. “The device uses a technology known as dynamic pulse detonation (DPD). A short but intense laser pulse creates a ball of plasma, and a second laser pulse generates a supersonic shockwave within the plasma to generate a bright flash and a loud bang,” he writes. The Plasma Acoustic Shield System will eventually combine a dynamic pulse detonation laser with a high power speaker for hailing or warning, and a dazzler light source.”
