Pulsed radiofrequency energy can produce an auditory perception
Controlled studies have reported clicks, buzzes, or related auditory sensations during exposure to particular pulsed radiofrequency conditions. Reviews describe the effect as distinct from ordinary airborne sound and dependent on pulse characteristics rather than simply average power.
This matters because it establishes a real interaction between absorbed pulsed energy and auditory perception. It does not mean every report of voices, tones, pressure, tinnitus, or sleep disruption has this cause.
Rapid thermoelastic expansion launches an acoustic wave
The research literature supports a thermoelastic explanation: a brief absorbed pulse produces a very small, rapid temperature rise, tissue expands, and an acoustic-pressure wave travels by bone conduction to the inner ear. The auditory system responds to the resulting mechanical wave.
That mechanism is more specific than the phrase microwave hearing. It ties the effect to pulse energy, absorption, anatomy, and acoustic propagation. Continuous-wave exposure and ordinary modulated communications do not automatically reproduce the conditions described in the experiments.
Frequency alone does not define the exposure
A useful study description includes carrier frequency, pulse width, repetition rate, energy per pulse, field geometry, subject position, equipment calibration, shielding, and controls for ordinary sound. Without those details, comparing a field report to a laboratory result becomes speculation.
Consumer broadband meters may miss short pulses, lack the required bandwidth, average away a transient, or provide no frequency-selective information. A phone application cannot substitute for calibrated radiofrequency instrumentation.
A mechanism is not a source attribution
A published mechanism establishes physical possibility under described conditions. Attribution in an individual case requires evidence that a matching exposure occurred: suitable measurements, time correlation, source characterization, reproducibility, controls, and exclusion of ordinary acoustic, medical, environmental, and equipment explanations.
Patents or laboratory studies can guide instrument selection and research questions. They do not establish deployment, operator identity, intent, or use against a named person. Those are separate claims with separate evidence burdens.
Build an investigation that could prove you wrong
Start with a time-stamped symptom and environment log, hearing and medical evaluation when appropriate, ordinary acoustic checks, and an instrument plan designed by a qualified RF professional. Preserve raw data, calibration records, antenna or probe information, and test conditions.
A strong protocol includes control periods, blinded comparisons when feasible, and criteria defined before the data is reviewed. Precision respects targeted individuals' reports because it seeks an answer that another person can test, not a conclusion protected from testing.
