  1. Deafness or some pemanent health impairment must be consequence of high intensity exposure to noise. Occupational hygiene describes sensorineural hearing loss with high level noise during long lapse (several years) of occupational contact with loud sound, not below 85 dB(A) -for instance, 10 years working in a noisy environment-. A severe impulse noise with level above 120 dB(A) -for instance a sound blast- could conduct to a permanent threshold shift, too. Moderate intensity noise may induce temporary effects, on regard vulnerability of subjects exposed to noise events.

    Brief exposure to noise episodes of less than 80 dB(A) should not lead to chronic health impairments. It must be consider selfprotection of stapedial reflex in the bone chain of the middle ear, which increases impedance to sound transmission.

    • One correction, if I may. I do not believe that deafness or hearing damage “must” be a consequence of high intensity noise exposure. There are many other causes of hearing loss, including ototoxic chemicals or medicines. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4693596/

      • Hi, Dr. Pompei. I am glad for being in touch with you. I was talking about noise as cause of the several health impairments. I do not reject other possible causes for the wide range of symptoms and signs reported. Sound level of the noise attacks never goes beyond 80 dB(AF). Sometimes spectra is flat like noise urban background performed with far sources. There is some kind of similarity to white noise at low and medium frequencies. Sometimes a pitch appears at 8 kHz in octave band and on 6300 and 8000 Hz in third octave. Continuous spectrum shows a 7 kHz pitch with bandwidth of 3 kHz superposed to background. Background urban noise has two typical shapes, one of them reflecting cosmopolitan far sources, another reflecting local sources like cricket songs. An important similitude appears between target and background noise with cricket songs. It appears a nearly flat spectrum with a high frequency pitch. Some target sounds shows no high frequency pitch. I remember that some exposed people said that they hear nothing out of rule but suffered consequences.

          Yes, Prof. Pompei we agree that there are other causes for hearing loss. Since we had so little hard data about the alleged victims we broadened the scope of our work to include ototoxicity and even infectious conditions. If sonic attacks are implausible, these other causes also seem unlikely as an explanation for all the cases. Maybe a few people were taking ototoxic medicine, or had some medical condition that caused some symptoms, but since the alleged incidents took place over several months and at different locations they are difficult to explain by a toxic or infections agent.

    The central point of all this is the no cooperation of the goverment of usa with cuban experts in the investigations. When two goverments have a good relationship and they have a problem, the affected goverment must help and cooperate with another goverment to resolve the problem; if it help or cooperation don’t possible, the affected goverment don’t want to have a good relationship with another goverment, is simple.

  3. The comment concerning acoustic intensity is correct for audible frequencies. But Jon, Pro and their Chinese group have found multiple effects of infrasound stimulation (including apoptosis) some of which can be seen even at low intensities. Ultrasound also has the property of long distance propagation.

    In my humble opinnion, if the Cuban Experts Committee wasn’t able to access the medical tests done to the people that were supposedly affected, and that the medical reports lacked data from the American authorities, the proper investigation couldn’t be completed because of the limitations given. So, the United States government can’t assure or make such allegations without an extensive investigation. And even if so, not only the reported diplomats would have presented the symptoms but all emplyees at the agency… So the facts don’t match.

    • Dr. Manuel Jorge Villar Kuscevic

      I fully agree with your judgement. We actually had access to a document delivered by the US authorities to our Ministry of Foreign Affairs, but this document lacked scientific rigor. The best thing would have been to exchange information and above all, to investigate the phenomenon directly with the alleged patients to reach a conclusion endorsed by evidence-based medicine. I can give you a lot more details but I don’t want to overwhelm you. I suggest you follow the online forum. There you will find many more details, especially the members of the Experts Committee that I am honored to chair. I wish you success in your residence.

  6. My tablet is changing my typing. I will be more careful. Ultrasound in my last post should be infrasound

  7. Mitchell Valdes-Sosa

    Gary you are right that infrasound can cause multiple effects, including damage to neurons and other cell types. Thanks for the input. I looked up articles by the group you mentioned as well those published by other groups. However, the work involves very high intensity infrasound (in one paper about 140 decibels), with sources very close to the tested tissue, and in most cases with prolonged exposure. This would require difficult to ignore electronic equipment. There are also reports of infrasound damage with large and old agricultural machinery. When one examines the circumstances of the alleged attacks, which have been described as focused- isolated- attacks directed towards one individual in hotel rooms or homes, with no one around either noticing the attack or suffering any effects, it is difficult to see how infrasound could be involved. The type of equipment described in the articles, much less agricultural machinery, was observed at the hotels, or houses, of the alleged victims.

  8. Mitchell, you are correct that much of the Chinese group’s work employed hi intensity infrasound. However, take a look at the following:

    Jin,….Pei (2017). Inhibitory effects of low decibel infrasound on the cardiac fibroblasts and the involved mechanism. Noise Health, 19, 149-153.

    They found that low intensity (about 80 db) had effects on hormone actions on cardiac fibroblasts (in vitro).

    This, of course, does not speak directly to the issue at hand, but merely to agree with others that it is unlikely that any purported effects were related to acoustic or ultrasonic stimuli (the latter would require prohibitive amounts of energy). Of the possibilities, however, infrasound perhaps cannot be summarily dismissed.

    • Mitchell Valdés-Sosa

      Gary you are right that infrasound should not be summarily dismissed. Thanks for calling attention to these reports. What we have concluded is that setting up sources for producing the required intensity and ensuring exposure for enough time to have the alleged effects is implausible.
