The Havana Syndrome and Microwave Weapons [Health Matters]
Abstract
The Havana Syndrome and Microwave Weapons [Health Matters] James C. Lin. The Havana Syndrome and Microwave Weapons [Health Matters]. IEEE Microwave Magazine. 22(11):13-14. Nov. 2021. doi: 10.1109/MMM.2021.3102201. Abstract Every few months, if not weeks, another mysterious attack on U.S. diplomatic and intelligence personnel is reported. Some of the attacks occurred years ago, while others were recounted as recently as July 2021 [1] – [3] . Over the past four or five years, nearly 200 U.S. personnel have reported similar attacks while working in places like Havana, Guangzhou, London, Moscow, Vienna, and Washington, D.C. The acute symptoms include headache and nausea immediately following the sounds of loud buzzing or bursts. The illness and symptoms have been called the “Havana Syndrome” after the place where cases were first reported. It refers to the range of symptoms first experienced by U.S. State Department personnel overseas. Excerpt 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 high power pulsed microwave radiation rather than blasting the subjects with conventional sonic sources. Microwave hearing doesn’t go through the ear; it goes directly from the brain tissue to the cochlea. Absorption of short pulses of microwave energy by brain tissues creates a rapid expansion of brain matter and launches an acoustic wave of pressure (sound 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. ieeexplore.ieee.org

Main findings
The article states that, assuming reported accounts are reliable, the microwave auditory effect could provide a scientific explanation for reported Havana Syndrome experiences. It describes how absorption of short, high-power pulsed microwave energy by brain tissue could generate an acoustic pressure wave perceived as sound without noticeable heating.
Outcomes measured
- Acute symptoms (e.g., headache, nausea) following perceived loud buzzing/bursts
- Microwave auditory effect (microwave hearing) as a proposed mechanism
Limitations
- Appears to be a commentary/overview rather than a controlled study
- Causal attribution depends on the reliability of reported accounts
- No exposure measurements (e.g., frequency, power, SAR) are provided in the abstract
- No clinical verification or diagnostic criteria are described in the abstract

"summary": "This IEEE Microwave Magazine piece discusses reports of “Havana Syndrome” among U.S. diplomatic and intelligence personnel and considers pulsed microwave exposure as a plausible explanation for the reported sounds and acute symptoms. It describes the microwave auditory effect mechanism, where short high-power microwave pulses could generate an acoustic pressure wave inside the head perceived as sound. The article frames this as plausible contingent on the reliability of the reported accounts and does not present direct exposure measurements or controlled evidence in the abstract.",

"The article describes nearly 200 reported cases of acute symptoms associated with perceived loud buzzing or bursts.",
"It proposes the microwave auditory effect as a scientific explanation for the perceived sounds, conditional on the reliability of reports.",
"It explains that pulsed microwaves can induce rapid tissue expansion and create an acoustic pressure wave traveling to the cochlea.",
"It notes that these short high-power pulses may not generate noticeable heating in brain tissue.",
"It suggests a directed beam of pulsed microwave radiation could be a covert delivery method compared with conventional sonic sources.",
"The abstract does not provide measured exposure parameters or direct causal evidence linking microwaves to the reported illness."
