The Microwave Auditory Effect

Abstract

The cascade of events illustrating the auditory perception of pulsed microwaves.

Analyses of Transient Energy Deposition in Biological Bodies Exposed to Electromagnetic Pulses Using Parameter Extraction Method

“…The errors match those derived by the method in [31] up to around 100 MHz whereas we can see an increase in the errors at higher frequencies over 200 MHz. The increase may be due to the difference in the update equation of the auxiliary current density in (14), which has second-order accuracy for both time and space, whereas that of [31] has only first-order accuracy in the space of the electric field and, therefore, the difference is larger at higher frequencies.…”

“…Microwave hearing is the phenomenon of perceiving an audible buzz or chirp sound as a result of energy absorption of microwave pulses by soft tissues inside the head [14], while the microwave heating effect is caused by the transformation of absorbed EM energy into heat. Note that the amount of absorbed energy may vary according to the location, tissue type, and geometrical factors of biological bodies, and hence it usually exhibits complex distribution depending on the exposed subject.…”

The Havana Syndrome and Microwave Weapons [Health Matters]

“…■ James C. Lin wave) that travels inside the head to the inner ear cochlea [7], [14]. The short high-power microwave pulses do not generate noticeable amounts of heat in the brain tissues.…”

“…Assuming reported accounts are reliable, the microwave auditory effect provides a scientific explanation for the Havana Syndrome [4], [5]. Pulsed microwaves can create an acoustic wave inside the head [6], [7], [14]. It is plausible that the loud buzzing, burst of sound, or pressure waves could have been covertly delivered using a beam of highpower pulsed microwave radiation rather than blasting the subjects with conventional sonic sources.…”

Dosimetry of Various Human Bodies Exposed to Microwave Broadband Electromagnetic Pulses

“…Meanwhile, biological effects due to EM pulses have been numerically and experimentally investigated. The effects include the microwave hearing effect, microwave heating effect, and electroporation (5)(6)(7)(8)(9). Consequently, international organizations have prescribed exposure limits for the temporal peak of specific energy absorption (SA) in published guidelines to prevent adverse effects, particularly of microwave hearing, which is considered an acute biological effect (10,11).…”
