Mammalian Auditory Responses to 3.0 GHz Microwave Pulses

A study of the effects of 3.0 GHz microwave pulses on the auditory systems of a number of mammalian species was conducted. Some human subjects heard a distinct "click" when irradiated with a sufficiently intense individual microwave pulse. Microwave induced auditory evoked responses were measured in the cat, dog, and chinchilia. The microwave peak power density levels at the threshold of producing an auditory response were determined for a number of human subjects in addition to the smaller animals. The inability of some of the human subjects to bear short microwave pulses was correlated with hearing losses above 8 kHz in frequency.
