The paper examines electrophysiological activity produced by exposing the
brains of laboratory animals to rectangular pulses of microwave energy. These
results suggest that a microwave auditory phenomenon is evoked by a mechanism
similar to conventional sound reception, and that the primary interaction site
is peripheral to the cochlea. It is shown that the peak pressure due to
thermal expansion is greater than the radiation pressure or electrostriction,
and that the induced sound frequency is only a function of the size and
acoustic property of the brain. Several suggestions were made for future
research in microwave auditory effect and its health implications.
