The microwave auditory effect, also called the microwave hearing effect or the Frey effect, is the perception of sound produced inside a person's head by pulsed or modulated radio frequency energy, with no receiving electronic device involved. It was first reported by people working near radar transponders during the Second World War, and the American neuroscientist Allan H. Frey was the first to study and publish on the phenomenon, in 1961. Its most widely accepted explanation is thermoelastic expansion of parts of the auditory apparatus caused by the radio frequency energy, though competing theories interpret the results of holographic interferometry testing differently.
