Microwave auditory effect

The Microwave Auditory Effect (MAE), also known as the Frey effect, is a phenomenon in which individuals perceive auditory sensations in the form of clicks or sounds in response to pulsed/modulated microwave frequencies. The effect was first reported by American neuroscientist Allan H. Frey in 1961, hence the alternative name.

Mechanism

The exact mechanism of the microwave auditory effect is not fully understood. However, it is believed to result from the thermal expansion of parts of the auditory apparatus, caused by the rapid heating and cooling due to the absorption of the microwave energy. The resulting pressure waves are then perceived as sound by the brain.

Research and Applications

Research into the microwave auditory effect has been carried out for potential applications in communication and military technology. The United States Department of Defense has shown interest in the technology for its potential use in non-lethal weapons.

Health Effects

While the microwave auditory effect does not cause permanent hearing damage, exposure to high-intensity microwave pulses can have other health effects, including headaches, concentration difficulties, and sleep disturbances.
