H. H. Seliger et al. · 1974
Researchers exposed people to pulsed microwave radiation and discovered they could hear 'clicks' synchronized with each pulse, even when the exposure was too brief to cause detectable tissue heating. The study demonstrated that microwaves create acoustic pressure waves in water through rapid thermal expansion, explaining this unique auditory phenomenon.

This 1974 study examined microwave radiation dosimetry methods during the early recognition of widespread microwave exposure from consumer devices. The research documented that Americans were already exposed to microwaves from 189,300 devices including ovens, radar, and communication equipment, with microwave oven usage growing 25% annually.
Eldon Byrd · 1974
This 1974 technical report by researcher Eldon Byrd explored the relationship between electrical energies and human psychology, examining how electromagnetic forces might influence brain function and mental processes. The work appears to bridge physics and psychology, investigating potential connections between electrical phenomena and human consciousness. This early research represents foundational thinking about bioelectromagnetics and the mind-body connection.
Michaelson SM · 1974
This 1974 review analyzed presentations from a major WHO-sponsored international symposium on microwave radiation health effects. The analysis examined research and expert opinions from the Warsaw symposium, representing early international scientific collaboration on microwave safety standards. This represents one of the first comprehensive international assessments of microwave radiation's biological effects on humans.
K. Foster · 1974
Researchers demonstrated that pulsed microwave energy can create acoustic sounds directly in water through thermal expansion. The study showed that these thermally-generated sound pulses match the intensity needed to explain the mysterious 'clicks' that people report hearing when exposed to identical microwave radiation.
Belkhode M., Johnson DL., Muc AM. · 1974
Researchers exposed human blood samples to 2.8 GHz microwave radiation at high power levels (500-1000 mW/cm²) to test whether microwaves could damage an important enzyme called glucose-6-phosphate dehydrogenase through non-thermal effects. They found that while heat from the microwaves reduced enzyme activity by up to 80%, the microwaves themselves caused no statistically significant damage beyond what heat alone would cause.
Eugene M. Taylor, Bonnie T. Ashleman · 1974
This 1974 technical report analyzed how microwave radiation directly affects the central nervous system to produce the microwave auditory effect - the phenomenon where people hear clicks, buzzes, or other sounds when exposed to pulsed microwaves. The research examined the neurological pathways involved when electromagnetic energy bypasses the ear and stimulates the brain's auditory processing centers directly.
JAMES P. MILLER · 1974
This 1974 research examined brain stimulation technologies including cranial electrotherapy stimulation (CET) devices like the Neurotone and Dormotron for treating neuroses and insomnia. The study explored early electrical therapy approaches that used extremely low frequency (ELF) electromagnetic fields to directly influence brain function. This represents some of the earliest documented research into therapeutic electromagnetic brain stimulation.
M. L. BELKHODE, D. L. JOHNSON and A. M. MUC · 1974
Researchers exposed human blood to 2.8 GHz microwave radiation at high power levels (500-1000 mW/cm²) to test effects on glucose-6-phosphate dehydrogenase, a key enzyme in cellular energy production. While heat from the microwaves reduced enzyme activity by up to 60%, the study found no non-thermal effects from the microwave radiation itself. This suggests microwave effects on this enzyme are purely due to heating, not electromagnetic fields.

Researchers tested whether 50 people could consciously or subconsciously detect 60 Hz magnetic fields at household appliance strength (few gauss). Initially some subjects showed remarkable detection abilities, but when acoustic noise and other environmental cues were eliminated, virtually no one could reliably sense the magnetic fields.
