>>>Deadly sound Jetpacks are not the only sci-fi staple that really exists. Already sonic weapons are being used to knock down opponents. Science fiction: Jetpacks in the film Since the 1960s, researchers have known that very deep noise, below the threshold of human hearing, can cause flesh to resonate, even distort vision. But it has proven difficult to make a powerful sound generator small enough to be portable, and being able to accurately direct the sound over a distance. Now, using higher frequencies, an MIT student has developed a device called an audio spotlight that can focus a tight beam of sound onto one spot several hundred feet away. A competing company, American Technology, is marketing a similar device. It is also said to be developing a more powerful rifle-sized version called a Directed Stick Radiator, intended for use in psychological warfare and crowd control. <<< news.bbc.co.uk US non-lethal weapon reports suppressed newscientist.com
