Psychophysical Analysis of Microwave Sound Perception

It has been found that humans perceive low-intensity, appropriately modulated electromagnetic energy in the microwave portion of the spectrum as a (radio frequency [rf] sound or microwave sound). determine if the repetition pitch phenomenon is a characteristic of microwave sound. It was found that it is not. The data indicate, with the microwave energy parameters used, that the subjects perceive the energy as 4.8 kHz ? 0.8 kHz sounds. This is related to the finding that clinically normal people with a marked loss in a band about 5 kHz cannot hear microwave sound, whereas clinically deaf people who are relatively normal at about 5 kHz can hear microwave sound. The data indicate that the microwave sound mechanism may involve only a portion of the cochlear apparatus. Thus, the microwave sound phenomenon may provide a unique probe for evaluating some of the concepts of auditory perception. This experimentation was undertaken to
