    This type of non-lethal technology has immense capabilities. For example a screeching moise can be made that could incapacitate any person who gets in the way of the broad beam. However, this noise uses microwave audial hearing which means that the brain recreates sound from the effects of microwaves thermally expanding the inner ear. Furthermore, warnings can be given to individuals unheard by others in the vicinity using microwaves.
    A US company claims it is ready to build a microwave ray gun able to beam sounds directly into people's heads.

    The device - dubbed MEDUSA (Mob Excess Deterrent Using Silent Audio) - exploits the microwave audio effect, in which short microwave pulses rapidly heat tissue, causing a shockwave inside the skull that can be detected by the ears. A series of pulses can be transmitted to produce recognisable sounds.

    The device is aimed for military or crowd-control applications, but may have other uses.

    Lev Sadovnik of the Sierra Nevada Corporation in the US is working on the system, having started work on a US navy research contract. The navy's report states that the effect was shown to be effective.

    Scarecrow beam?

    MEDUSA involves a microwave auditory effect "loud" enough to cause discomfort or even incapacitation. Sadovnik says that normal audio safety limits do not apply since the sound does not enter through the eardrums.

    "The repel effect is a combination of loudness and the irritation factor," he says. "You can't block it out."

    Sadovnik says the device will work thanks to a new reconfigurable antenna developed by colleague Vladimir Manasson. It steers the beam electronically, making it possible to flip from a broad to a narrow beam, or aim at multiple targets simultaneously.

    Sadovnik says the technology could have non-military applications. Birds seem to be highly sensitive to microwave audio, he says, so it might be used to scare away unwanted flocks.

    Sadovnik has also experimented with transmitting microwave audio to people with outer ear problems that impair their normal hearing.

    Yes, because controlling revolting people is very important to controlling everything else.

    A possible use of this technology is in a hostage situation where 'silent' sound could be projected into the heads of the hostages to enable the Police or Security Forces to have a tactical advantage. Additionally, people who are deaf can have the power of listening to speech once again. The possibilities are numerous.

    They had something similar to this over here it was dubbed the 'Mosquito', it was certain sound frequencies to cause pain and debilitation. It was used for targeting groups of teenagers to stop them congregating in certain areas. It was designed so that only teenagers and adolescents could hear the frequencies, so this was mainly a civilian application but it's usage did provoke some outrage and an awful lot of controversy. What is clear though is we now have the technology to create these types of devices and if they could be applied to hostage situations and save lives then it's definitely a step in the right direction.

    I have heard of the Mosquito. However, the technology in the OP seems to be a league above the Mosquito. For example, you could tell a whole opposing division in a battle to stop and give up and then flick to individual commanders to tell them that they would not be prosecuted if they ordered their forces to give up. I could imagine that a voice straight to the head would be very disconcerting to hostages in a hostage situation.

    I'm more interested in the potential for an effective "stun gun" application. How large does the projector have to be?

    Haven't they found that it is even more effective to play opera music or cheesy old pop songs? "Aaarrgh! Barry Manilow! Run for it!
