SECTION II — MILITARY AND PUBLIC-SAFETY TECHNOLOGIES
11. Long-Range Acoustic Devices (LRADs)
Technology class: Directional acoustic communication.
LRAD-type systems use high-output acoustic equipment to project speech, warning messages, and tones over distance.
Potential applications include:
- Public announcements.
- Maritime communications.
- Emergency warnings.
- Crowd communication.
- Law-enforcement and security operations.
- Perimeter warnings.
What they demonstrate: Sound can be projected directionally and made intelligible over substantial distances under suitable conditions.
What they do not demonstrate: Direct brain-to-brain communication or RF-induced internal speech.
An acoustic device may be relevant to an investigation of a sound with an uncertain origin, but the existence of the technology does not establish that it was present in a particular incident.
Public product information:
https://www.lradx.com/
A public-sector equipment report describing LRAD use is also available here:
https://wp.sbcounty.gov/sheriff/wp-content/uploads/sites/17/MilitaryEQPT/Military-Equipment-Report-03-29-2024-FINAL.pdf
12. Acoustic Hailing Devices and Directional Audio Systems
These systems overlap with LRAD technology but encompass a broader range of directional speakers and specialized acoustic equipment.
Potential functions include:
- Directing spoken messages toward a particular area.
- Improving speech intelligibility in noisy environments.
- Delivering warnings without broadcasting equally in every direction.
- Focusing acoustic energy for specialized communications.
Relevant engineering topics include beam formation, acoustic propagation, reflections, distance, frequency response, and environmental noise.
These systems transmit ordinary acoustic energy. They should not be classified as brain-computer interfaces.
13. Active Denial System (ADS)
Technology class: Millimeter-wave directed-energy system.
The Active Denial System is a publicly documented defense technology developed to produce a strong heating sensation at the surface of the skin using millimeter-wave energy.
Its intended mechanism differs from both directional sound and the microwave auditory effect.
Research relevance: ADS provides an example of a directed-energy system designed around a specific biological interaction.
Critical distinction: Evidence that a millimeter-wave system can produce a surface-heating sensation does not establish that it can transmit intelligible speech directly into the brain, read thoughts, or produce any unrelated claimed effect.
Any discussion of ADS should distinguish the documented mechanism, intended use, test history, exposure conditions, and safety limitations.
14. Electronic-Warfare and RF Systems
Electronic-warfare systems are designed for functions such as detecting, disrupting, deceiving, or interfering with electronic systems.
Examples of relevant technology classes include:
- Radar systems.
- RF receivers and signal analyzers.
- Communications jamming systems.
- Electronic countermeasures.
- Signal intelligence equipment.
- RF direction-finding systems.
- Electronic protection systems.
Research relevance: These systems demonstrate the extensive technical field of RF transmission, reception, measurement, and interference.
Important limitation: A system that can transmit or manipulate RF signals is not automatically capable of interacting with the human nervous system in a specific way. Biological effects require separate evidence.
15. Radar-Based Human Sensing
Some radar systems can detect motion or movement-associated changes in reflected RF signals. Research applications can include respiration monitoring, occupancy detection, or movement detection.
The system generally analyzes reflected signals rather than decoding a person's arbitrary thoughts.
Research relevance: Radar sensing may be important when assessing claims about remote movement detection or environmental RF systems.
Limitations: Detection of movement or breathing is not evidence of mind reading, auditory stimulation, or voice transmission.
16. RF Exposure Measurement and Monitoring
RF measurement equipment is used in telecommunications, engineering, occupational safety, research, and regulatory compliance.
Examples include:
- Spectrum analyzers.
- RF power meters.
- Field-strength meters.
- Calibrated broadband exposure meters.
- Frequency-selective measurement systems.
- Specialized receivers for pulsed signals.
These instruments have different capabilities and limitations.
A consumer RF meter may not identify every possible waveform or short-duration pulse. Conversely, an unusual reading does not establish that a signal caused a symptom.
A defensible investigation requires calibrated equipment, suitable frequency coverage, a documented measurement protocol, and qualified interpretation.
17. Psychological Operations and Influence Technologies
Military and government organizations have historically used communication and influence methods, including:
- Radio broadcasts.
- Loudspeaker announcements.
- Leaflets and printed messaging.
- Public information campaigns.
- Strategic communication.
- Deception and misinformation.
- Digital information operations.
These are communication and influence techniques, not inherently neural technologies.
They can be relevant to historical research on the phrase “Voice of God,” but they should not be conflated with a device that directly generates auditory perceptions inside a person's brain.
SECTION III — ESTABLISHED NEUROTECHNOLOGY AND NEURAL STIMULATION
18. Electroencephalography (EEG)
EEG measures electrical activity from the scalp.
Applications include:
- Clinical assessment of brain activity.
- Epilepsy evaluation.
- Sleep studies.
- Research into attention and cognition.
- Brain-computer interfaces.
- Experimental brain-to-brain communication systems.
EEG signals are affected by noise, movement, electrode placement, and the limited spatial resolution of scalp measurements.
EEG can support specific forms of signal classification, but it does not provide unrestricted access to a person's thoughts.
19. Functional Magnetic Resonance Imaging (fMRI)
fMRI measures changes associated with blood oxygenation and blood flow that indirectly reflect neural activity.
It is used in neuroscience and clinical research.
Certain research models can infer aspects of stimuli or task-related mental content under controlled conditions. These systems require data, appropriate scanning equipment, and carefully designed methods.
Limitation: fMRI is not a practical general-purpose device for covertly reading arbitrary thoughts from a person at a distance.
20. Transcranial Magnetic Stimulation (TMS)
TMS uses magnetic pulses to induce electrical activity in targeted brain tissue.
Applications include certain clinical treatments and neuroscience research.
TMS has also been used as the stimulation component of experimental brain-to-brain interfaces.
Limitation: The existence of TMS does not establish a means of transmitting complex speech remotely without the appropriate equipment and controlled conditions.
21. Transcranial Electrical Stimulation
This category includes methods such as:
- Transcranial direct-current stimulation (tDCS).
- Transcranial alternating-current stimulation (tACS).
- Related noninvasive electrical-stimulation approaches.
These methods deliver electrical currents through electrodes placed on the scalp.
They are studied for potential effects on neural activity, rehabilitation, and clinical or experimental applications.
Limitation: These are not equivalent to a wireless device that can selectively transmit words into someone's mind from an arbitrary distance.
22. Focused Ultrasound Neuromodulation
Focused ultrasound is being studied for its ability to interact with targeted tissue, including nervous-system structures.
Research questions include whether ultrasound can modulate neural activity with sufficient spatial and temporal precision for particular therapeutic or scientific applications.
The field includes different approaches, equipment designs, and levels of experimental maturity.
Limitation: Evidence for ultrasound-based neuromodulation under specified conditions does not establish unrestricted remote voice transmission or arbitrary control of thoughts.
23. Deep Brain Stimulation (DBS)
DBS uses implanted electrodes to deliver electrical stimulation to selected brain structures.
It is an established treatment for certain neurological conditions and is also used in research.
DBS requires an implanted system and clinical management.
Limitation: DBS is not a technology for reading arbitrary thoughts or secretly communicating spoken messages to an unimplanted person at a distance.
24. Cortical Implants and Intracortical Recording
Implanted electrode arrays can record neural activity from selected areas of the brain.
Research applications include:
- Motor control.
- Assistive communication.
- Speech decoding.
- Prosthetic control.
- Sensory feedback.
- Rehabilitation.
These systems may provide richer neural information than many noninvasive approaches, but they involve implantation, signal-processing systems, and task-specific decoding.
They should be distinguished from remote, noninvasive claims.
25. Cochlear Implants and Auditory Neuroprostheses
Cochlear implants convert sound into electrical stimulation delivered to the auditory nerve.
They are established medical devices for eligible people with significant hearing loss.
Other auditory neuroprosthesis research explores more direct interaction with the nervous system to improve hearing or restore function.
Relevance: These technologies demonstrate that auditory perception can be supported through carefully designed medical interfaces.
Limitation: They do not demonstrate covert voice transmission to a person without a corresponding interface.
SECTION IV — PRIVATE-SECTOR NEUROTECHNOLOGY COMPANIES

Their technologies vary widely, from scalp-based EEG systems to implanted interfaces.
These organizations should be evaluated individually according to the device, regulatory status, peer-reviewed evidence, study population, and specific demonstrated task.
SECTION V — PRIVATE-SECTOR AUDIO AND COMMUNICATION TECHNOLOGIES
31. Directional Audio and Parametric Speakers
Private-sector companies manufacture directional speakers and parametric audio systems for specialized communications, installations, exhibits, retail environments, and other applications.
Such systems can create a narrower sound field than conventional speakers under appropriate conditions.
Relevant to: Claims involving sound apparently coming from a particular direction or being heard in a localized area.
Not evidence of: Direct neural transmission, brain-to-brain communication, or RF-induced speech.
32. Professional Acoustic Equipment and Sound Systems
Commercial sound equipment includes:
- Directional speakers.
- Public-address systems.
- Wireless microphones.
- In-ear monitoring systems.
- Noise-cancellation systems.
- Hearing-assistance systems.
- Acoustic measurement equipment.
These technologies can produce, transmit, record, filter, or alter sound.
In an investigation of an unexplained auditory event, conventional acoustic sources should be considered before attributing the event to a more unusual mechanism.
33. Hearing Aids and AI-Based Speech Enhancement
Modern hearing aids and assistive listening systems may use:
- Directional microphones.
- Noise reduction.
- Speech enhancement.
- Adaptive gain.
- Feedback suppression.

Their goal is generally to improve access to environmental sound.
Relevance: These technologies illustrate how software and signal processing can change what a listener hears without directly stimulating the brain.
34. Cochlear Implant Manufacturers
Companies such as Cochlear, MED-EL, and Advanced Bionics develop auditory implants and associated equipment.
These devices are medical systems designed to support hearing in eligible patients.
Relevance: They provide examples of engineered auditory stimulation through a medically implanted interface.
Limitation: Their existence does not establish an equivalent capability without an implanted device.

Technology classes include:
- Cellular base stations.
- Mobile phones.
- Wi-Fi access points.
- Bluetooth devices.
- Satellite communications.
- Point-to-point microwave links.
- Private wireless networks.
These systems transmit and receive electromagnetic signals for communication.
The presence of an RF transmitter in an environment does not establish that it is producing an auditory effect. Signal characteristics, exposure conditions, and a plausible causal mechanism must be assessed independently.
36. Software-Defined Radio (SDR)
Software-defined radios use software-controlled processing for some radio functions.
They are used in communications engineering, spectrum research, signal analysis, and educational laboratories.
Relevance: SDRs can help researchers investigate identifiable RF signals when configured with suitable hardware and methods.
Limitation: An SDR is a radio-analysis platform, not proof of a device capable of neural stimulation or voice-to-skull communication.
37. RF Direction Finding and Signal Geolocation
Specialized systems can estimate the direction or location of a radio transmitter by analyzing received signals.
Methods may use multiple antennas, multiple receivers, or signal-processing techniques.
Relevance: These methods can support an evidence-based investigation of a specific RF source.
Limitations: Results depend on signal conditions, equipment, geometry, and the method used. Detecting a transmitter does not establish that it caused a person's symptoms.
38. Passive RF Sensing
Passive sensing systems analyze existing signals or their reflections to infer certain environmental conditions.
Possible applications include occupancy detection, movement monitoring, and research into wireless sensing.
Relevance: Relevant to questions about remote sensing of physical activity.
Limitation: Detecting movement or environmental changes does not establish the ability to read thoughts or induce speech.
39. Acoustic and RF Monitoring Equipment
Commercial monitoring systems can measure environmental noise or electromagnetic field levels.
Examples include:
- Sound-level meters.
- Acoustic dosimeters.
- Spectrum analyzers.
- RF field meters.
- Frequency-selective receivers.
- Data-logging equipment.
The right instrument depends on the question being tested. A generic meter may not detect every signal or provide sufficient detail to identify its source.
Any meaningful assessment should record instrument specifications, calibration, measurement conditions, uncertainty, and applicable standards.
SECTION VII — PSYCHOLOGICAL, COGNITIVE, AND DIGITAL INFLUENCE TECHNOLOGIES

These methods can influence what information a person encounters and how a digital service is presented.
Limitation: Behavioral influence through content and interfaces is not evidence of direct neural control or RF-induced auditory perception.
41. Neuromarketing and Psychophysiological Research
Some private research organizations use measures such as eye tracking, skin conductance, facial-expression analysis, or other physiological indicators to study responses to stimuli.
These measures can provide limited information about attention or arousal under specific conditions.
They cannot reliably reveal every private thought, intention, or belief.
42. Eye Tracking and Gaze Estimation
Eye-tracking systems estimate where a person is looking or measure eye movements.
Applications include accessibility, research, usability testing, and some forms of attention analysis.
Limitation: Gaze estimation is not thought reading. A person's gaze does not reliably reveal the complete content of their thoughts.
43. Facial and Voice Analysis
AI systems can classify certain visible or audible patterns, including speech content, voice characteristics, or facial movements.
Accuracy and appropriate interpretation depend on the system, training data, recording conditions, and task.
These technologies can raise privacy concerns, especially when used without meaningful consent, but they should not be represented as reliable access to all internal mental states.
44. Digital Surveillance and Data Aggregation
Digital surveillance can involve collecting information from devices, networks, sensors, applications, or publicly available sources.
Possible data types include:
- Location data.
- Device identifiers.
- Communications metadata.
- Online activity.
- Audio or video recordings.
- Access logs.
- Environmental sensor data.
Such collection may be lawful or unlawful depending on the context, method, consent, jurisdiction, and applicable law.
Limitation: Evidence of digital surveillance does not establish that a person is experiencing RF auditory effects or direct neural stimulation.
SECTION VIII — RELATED SCIENTIFIC METHODS THAT SHOULD NOT BE CONFUSED WITH VOICE-TO-SKULL TECHNOLOGY

SECTION X — EYEHEART INTELLIGENCE RESEARCH PRIORITIES
The following priorities would help turn this inventory into a systematic research database.
Priority 1: Neural-interface programs
Compile public records for DARPA N³, NESD, ElectRx, Neuro-FAST, RAM, INI, Firefox, ARPA-H HEARING, and NIH-supported neurotechnology initiatives.
Record program dates, research goals, participating institutions, public deliverables, and documented results.
Priority 2: Auditory technologies
Catalog microwave auditory-effect studies, directional acoustic systems, auditory implants, hearing restoration research, and speech-decoding interfaces.
Clearly distinguish acoustic transmission from RF-related auditory perception and direct neural stimulation.
Priority 3: RF patents and engineering records
Review the RF-hearing patents identified in the preceding EyeHeart Intelligence article, along with related patent citations and any independently verifiable experimental work.
Priority 4: Private-sector neurotechnology
Build a company-level register of neural-interface developers, their devices, regulatory status, clinical trials, peer-reviewed studies, and stated applications.
Priority 5: Human rights and research governance
Review informed-consent requirements, neural-data privacy, clinical-device oversight, exposure standards, and procedures for investigating credible allegations of harm.
Priority 6: Forensic measurement
Identify qualified audiologists, environmental acoustics professionals, RF engineers, and clinicians who can evaluate specific questions using appropriate methods.
Priority 7: Incident-specific evidence
Develop a standard evidence template that separates firsthand observations, independent measurements, medical findings, technical interpretations, and unresolved questions.
FINAL EYEHEART INTELLIGENCE™ POSITION
The public record documents a broad and evolving landscape of government-sponsored neurotechnology research, medical neural interfaces, directional acoustic systems, RF engineering, sensory prosthetics, and commercial brain-computer interfaces.
These technologies are relevant to understanding what humans can measure, transmit, decode, stimulate, or perceive under defined conditions.
However, the existence of a related technology does not establish that a more expansive or alleged capability exists. Neural recording is not unrestricted thought reading. Directional sound is not direct brain-to-brain communication. RF transmission is not automatically neural stimulation. A patent is not proof of operational deployment. A reported symptom is not, by itself, proof of a particular exposure.
The appropriate investigative standard is to examine each technology's mechanism, maturity, independently demonstrated capability, limitations, safety implications, and relevance to any specific allegation.
EyeHeart Intelligence supports scientific rigor, transparency, human dignity, informed consent, privacy protection, and independent evidence-based investigation.
Research principle: Identify the technology. Verify the capability. Document the evidence. Protect human rights. Distinguish what is known from what remains uncertain.
