Hyper Sonic Sound

HSS is not the SS may be it can be more lethal than it. Why do they call these machines non lethal, I some times wonder? These things are more lethal than all the other machines in existence. They encroach into your privet world, into your private thoughts and into your very being. If that is not lethal what is?

HSS is Hyper Sonic sound. Researches were on for using them on humans for ever so long. Those were classified efforts and are still unknown to the world. But now there are commercial products which boast of a definite level of sophistication to influence the common man. Some government as well as privet organizations are buying them up and are probably making use of them to control people.

The technology is simple; ordinary voices/sounds are mixed with two streams of hyper sonic sound which is beyond the power of normal detection by the human ear and is beamed to a specific spot. In a sense voice is carried by the super sonic spectrum of sound and projected to a particular spot. The air molecules on that spot convert the voice in to an audible sound. If a person gets near this spot, he would hear the voice and would be stunned. He would think that the voice is coming from inside his head. If he moves away the voice would cease and no one near him would be hearing it if they are outside the range of the beam.

The above is the least lethal use of the machine. The property of sound to perform destructive things is already known to humanity. Singers with powerful voices have shattered glass ware as we know. Sound can be beamed to cause pain, distress, nausea and several other effects on humans. The available modern commercial HSS applications is reported to penetrate more than one inch below the surface of the human skin and if the power of the beam is increased it would heat up the body causing great discomfort.

I do not think all the effects of the machines are catalogued. There could be subtle psychological changes too in those subjected to this kind of torture.

Are there any legislations to cope with such unknown menaces and to control their harmful uses?
