Microwave Auditory Effects Among U.S. Government Personnel Reporting Directional Audible and Sensory Phenomena in Havana
Abstract
Microwave Auditory Effects Among U.S. Government Personnel Reporting Directional Audible and Sensory Phenomena in Havana James C. Lin. Microwave Auditory Effects Among U.S. Government Personnel Reporting Directional Audible and Sensory Phenomena in Havana. IEEE Access, vol. 10, pp. 44577-44582, 2022, doi: 10.1109/ACCESS.2022.3168656. Abstract The mysterious incidents on diplomatic and intelligence personnel began in 2016. Since then, nearly 200 incidents have been reported. The illnesses and symptoms are called Havana Syndrome, named for the city where cases were first reported. The initial accounts from Havana include hearing of loud high-pitched sounds, localizing the sources as coming from above or behind the head, experiencing a directional sound that ceases if one steps away, the covering of ears not making any difference, some hearing the sound but others in the same room not hearing it, or hearing it in one part of a room but not in other areas. Assuming the reported symptoms and accounts are consistent, the microwave auditory effect provides a scientific explanation for Havana Syndrome. Excerpts Although the required peak power densities are high, they are achievable with existing high-power commercial and military microwave systems operating under pulsed conditions [25]. Significantly, they also fall within the permissible “safe” limits of currently promulgated safety standards and protection guidelines, The required microwave technology is mature and in general, commercially available in many developed countries. confirming the conclusion of earlier studies. Furthermore, the study showed that to generate tissue injuring level of high-power microwave induced acoustic pressures inside the human brain, the theoretical microwave pulse induced temperature elevation would be substantially below 1o C (see Table 2), which is again “safe” according to currently promulgated RF and microwave safety protection guidelines. ieeexplore.ieee.org

Main findings
The paper argues that, assuming the reported accounts are consistent, the microwave auditory effect could provide a scientific explanation for the directional audible phenomena reported in Havana Syndrome cases. It states that required peak power densities for microwave auditory effects are achievable with existing pulsed high-power microwave systems and claims these could fall within currently promulgated safety limits; it also states that theoretical pulse-induced temperature elevation could be substantially below 1°C even for tissue-injuring acoustic pressures.
Outcomes measured
- Directional audible sensations (microwave auditory effect)
- Reported symptoms/illnesses described as Havana Syndrome
- Theoretical tissue-injuring acoustic pressures in the brain
- Theoretical microwave pulse-induced temperature elevation
Limitations
- Appears to be a narrative/theoretical argument rather than an empirical study of exposed individuals (no methods or measurements described in the abstract).
- Relies on the assumption that reported symptoms and accounts are consistent.
- No exposure characterization (frequency, power density, duration) is provided in the abstract.
- No sample size, case ascertainment details, or direct clinical outcome assessment is provided in the abstract.

"summary": "This IEEE Access article discusses reports of directional audible and sensory phenomena among U.S. government personnel associated with “Havana Syndrome.” It proposes the microwave auditory effect as a scientific explanation for the reported directional sounds, contingent on the consistency of the accounts. The abstract further claims that pulsed high-power microwave systems could produce the required peak power densities and that theoretical temperature rises could remain below 1°C even when acoustic pressures reach tissue-injuring levels.",
