Microwave auditory effect ? [View all]
The first American to publish on the microwave hearing effect was Allan H. Frey, in 1961. In his experiments, the subjects were discovered to be able to hear appropriately pulsed microwave radiation, from a distance of 100 meters from the transmitter. This was accompanied by side effects such as dizziness, headaches, and a pins and needles sensation.
Sharp and Grove developed 'receiverless' wireless voice transmission technologies for the Advanced Research Projects Agency at Walter Reed Army Institute of Research, in 1973. In the above mentioned journal entry to The American Psychologist, Dr. Don Justesen reports that Sharp and Grove were readily able to hear, identify, and distinguish among the single-syllable words for digits between 1 and 10 . Justesen writes, "The sounds heard were not unlike those emitted by persons with an artificial voice box (Electrolarynx). Communication of more complex words and of sentences was not attempted because the averaged densities of energy required to transmit longer messages would approach the [still] current 10mW/cm² limit of safe exposure."[6]

Alexis told police he believed people were following him and "sending vibrations into his body," according to a Newport police report.
He told police that he had twice moved hotels to avoid the noise he heard coming through the floor and the ceiling of his rooms, and that the people following him were using "some sort of microwave machine" to prevent him from sleeping.
