Did you know that many deaf people can actually hear microwave radiation? It's called the Frey Effect/Microwave Hearing, a fascinating interaction between Microwaves and the brain. Unlike regular hearing, which relies on sound waves traveling through the ear, this “hearing” occurs directly in the brain. Microwaves interact with the brain’s cells, which produce tiny electrical fields, creating the perception of sound WITHOUT INVOLVING THE EARS. The effect has been observed in microwave frequencies, between 900 MHz and 2.45 GHz, with power densities as low as 0.01 mW/cm² The key to this effect is that the microwaves must be pulsed, not continuous, as the rapid bursts are what trigger the brain’s response
