- Microwave_auditory_effect abstract "The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of audible clicks (or, with modulation, whole words) induced by pulsed/modulated microwave frequencies. The clicks are generated directly inside the human head without the need of any receiving electronic device. The effect was first reported by persons working in the vicinity of radar transponders during World War II. These induced sounds are not audible to other people nearby. The microwave auditory effect was later discovered to be inducible with shorter-wavelength portions of the electromagnetic spectrum. During the Cold War era, the American neuroscientist Allan H. Frey studied this phenomenon and was the first to publish information on the nature of the microwave auditory effect.Pulsed microwave radiation can be heard by some workers; the irradiated personnel perceive auditory sensations of clicking or buzzing. The cause is thought to be thermoelastic expansion of portions of auditory apparatus. The auditory system response occurs at least from 200 MHz to at least 3 GHz. In the tests, repetition rate of 50 Hz was used, with pulse width between 10–70 microseconds. The perceived loudness was found to be linked to the peak power density instead of average power density. At 1.245 GHz, the peak power density for perception was below 80 mW/cm2.[citation needed] However, competing theories explain the results of interferometric holography tests differently. In 2003, the US Navy conducted research on an MAE system they called MEDUSA (Mob Excess Deterrent Using Silent Audio) as a way to remotely, temporarily incapacitate personnel. The system relied on the principle of MAE, varying the power and parameters of the microwave pulses “to raise the auditory sensation to the ‘discomfort’ level, deterring personnel from entering a protected perimeter or, if necessary, temporarily incapacitating particular individuals.”In 2008, Sierra Nevada Corporation, a contractor that worked on the Navy's MEDUSA research, announced that they were seeking funding from the US Department of Defense to build demonstration and transportable versions of the system.".
