Overview
Microwave hearing (also called RF hearing or the microwave auditory effect) is a documented neurological phenomenon where individuals perceive audible sounds—ranging from buzzing and clicking to intelligible speech—originating within their own heads when exposed to pulsed microwave radiation. This symptom has been extensively documented in both scientific literature and government research programs, with particular relevance to neurostrike victim testimony.

Government Research and FOIA Evidence
NASA Abstract AD-A090426 (June 1, 1980)
The National Aeronautics and Space Administration conducted research on microwave hearing with explicit military applications:
> "A decoy and deception concept presently being considered is to remotely create the perception of noise in the heads of personnel by exposing them to low power, pulsed microwave. When people are illuminated with properly modulated low power microwaves the sensation is reported as a buzzing, clicking, or hissing which seems to originate (regardless of the person's position in the field) within or just behind the head.
> The phenomena occurs at average power densities as low as microwatts per square centimeter with carrier frequencies from 0.4 to 3.0 GHz [within frequency range of 400 MegaHertz (MHz) to 3 GigaHertz]. By proper choice of pulse characteristics, intelligible speech may be created.
> Before this technique may be extended and used for military applications, an understanding of the basic principles must be developed. Such an understanding is not only required to optimize the use of the concept for camouflage, decoy and deception operations but is required to properly assess safety factors of such microwave exposure."
Defense Intelligence Agency Report (1976)
The DIA released a report on Soviet microwave research:
> "Sounds and possibly even words which appear to be originating intracranially (within the head) can be induced by signal modulation at very low average power densities... Communist work in this area has great potential for development into a system for disorienting or disrupting the behavior patterns of military or diplomatic personnel."
U.S. Air Force Research (1997)
According to Microwave News (Louis Slesin, Jan/Feb 1997):
> "It would also appear possible to create high fidelity speech in the human body, raising the possibility of covert suggestion and psychological direction. When a high power microwave pulse in the GHz range strikes the human body, a very small temperature perturbation occurs... If a pulse stream is used, it should be possible to create an internal acoustic field in the 5-15 kHz range, which is audible. Thus it may be possible to 'talk' to selected adversaries in a fashion that would be most disturbing to them."
Military Applications and Programs
JASORS/SORDAC Program (Lopez, International Defense Review, March 1993)
- Joint Advanced Special Operations Radio System being developed by Harris Corporation
- SORDAC investigating long-range and "far-future" weaponry including:
- Microwave hearing as a psychological warfare tool
DARPA Augmented Cognition Program (FY2003 Budget)
The program aims to develop technologies that:
- Measure cognitive state in real time and manipulate it
- Integrate digital devices supporting memory, perception, and thinking
- Link support with user's context state information
- Directly improve warfighter cognitive performance
Human Cognome Project (National Science Foundation/Commerce report, 2002)
Participants from NASA, ONR, DARPA, Sandia National Labs, USAF Research Labs, Raytheon, Lucent Technologies, MIT, and Stanford proposed:
- Complete mapping of connections in the human brain
- Uploading aspects of individual personality to computers and robots
- Brain-machine interfaces enabling control actions prior to thoughts being fully formed
Mechanism
The microwave auditory effect occurs through thermoelastic expansion. When pulsed microwave radiation strikes tissue, a very small temperature perturbation causes rapid thermal expansion of the slightly heated tissue. This expansion is fast enough to produce an acoustic wave that propagates through the head and is perceived as sound originating within or just behind the head.
Frequency Range
- Carrier frequencies: 0.4 to 3.0 GHz (400 MHz to 3 GigaHertz)
- Audible range produced: 5-15 kHz
- Power densities: As low as microwatts per square centimeter

Microwave hearing is one of thirteen documented symptoms reported by neurostrike victims. The phenomenon's documented existence in government research programs, combined with the proliferation of microwave towers worldwide at an explosive rate over recent years, provides a framework for understanding neurological disruption claims from affected individuals.
The convergence between Eastern and Western findings on neural responses to microwave exposure—documented in comprehensive reviews including behavioral changes, cellular effects, pharmacological analyses, and emerging consensus—supports the validity of victim reports while highlighting gaps in official acknowledgment.
