The Frey Effect - the future of sound reproduction?

US Army toyed with telepathic ray gun

A recently declassified US Army report on the biological effects of non-lethal weapons reveals outlandish plans for "ray gun" devices, which would cause artificial fevers or beam voices into people's heads....................

A word in your ear

Some of the technologies are conceptual, such as an electromagnetic pulse that causes a seizure like those experienced by people with epilepsy. Other ideas, like a microwave gun to "beam" words directly into people's ears, have been tested. It is claimed that the so-called "Frey Effect" – using close-range microwaves to produce audible sounds in a person's ears – has been used to project the spoken numbers 1 to 10 across a lab to volunteers'.

I hear voices.

Good thing I've almost perfected my Interplanetary Cosmic Confusion Matrix Aluminum foil cap with the updated Beer Goggles... Arf, Arf, Bad Dog! Can't... Get...Dick... Cheeney... Out of my Head... Flying Wombats!!! Hummm... I think this thing needs a little tweaking.

Hey don't knok it, these types of interference pattern reproduction systems have been around.

There was the vaunted HSS that seems to have fizzled. Here are some notes on that:

HyperSonicTM Sound (HSSTM) from American Technology Corporation employs ultrasonics to create audible sound in the air. It works by using harmless ultrasonic tones that we can't hear. These tones use the property of air to create new tones that are within the range of human hearing. The result is audible sound. The acoustical sound wave is created directly in the air molecules by down-converting ultrasonic energy to the frequency spectrum we can hear.

HyperSonic Sound is produced without the excess baggage of conventional speakers--there are no voice coils, cones, crossover networks, or enclosures. The result is sound with a potential purity and fidelity never before attained.

Sound quality is no longer tied to speaker size. The HyperSonic Sound system holds the promise of replacing conventional speakers wherever they are used: in the home, in movie theaters, in automobiles--everywhere.

And to think...No one believed me that the voices in my head was the government trying to control me.
