back to article Cubans launching sonic attacks on US embassy? Not what we're hearing, say medical boffins

Sonic attacks supposedly launched back in 2016 by dastardly Cubans on innocent US diplomats in Havana may well be psychosomatic rather than the result of technology aimed at the embassy. A paper by researchers from the US and New Zealand casts doubt on the definition of so-called "Havana Syndrome" as a new illness, proposing …

    Mass hysteria. I'd say that this is what is happening in the Orange Goon's head

    And he wants to infect the rest of His Royal Staff to the same. (Staff is not a reference to a stiff rod in this case.)

    Given the constant projection of evil on everyone else and that the evil is usually centered on the Goon and it's (R)epuglicon party, I'm guessing that he just released more top-secret information about what the US is actually working on.

    Also, didn't I read something recently about other scientists describing the symptoms as coming from some air borne common pathogen?

    opportunity missed

    The CIA should have sent an ultra secret crew to the embassy with an "experimental countermeasure". Sugar pill, Doritos bag over the skull, maybe a pair of Beats headphones (shhh, they're disguised as Beats headphones, they're really an active anti-infrasonic countermeasure). Get a handful of staff in a super secure area of the embassy and let them know that they're part of the countermeasures test group. Make them swear to keep it secret, because we want the Cubans to think their weapon is working.

    Hmmm, maybe they did that, the took the gag so far that they even had some medical researchers write a paper saying that the whole thing was psych..bgddhngvf

      Experimenting with Low Frequencies

      Some of us future engineering types, in our youth, noticed that if a car was traveling at the right speed with the window(s) opened just so, the occupants would be pummeled with pulsing sound waves that caused intense confusion and extreme discomfort. In my beater I had to be doing a tad shy of 60 mph and both front windows rolled down (yes kids, "rolled" down) about 3/4 the way.

      Playing around in high school shop class we created some similar pulses using some frequency generators and a pair of crappy stereo bass speakers. I remember the two speaker frequencies had to be the same but out of phase.

      Even as we experienced this it was tough to localize where the effect was in the body. It could be the chest cavity, or just behind the ears. One guy said he felt it in his shoulder blades. But it was intensely uncomfortable to stand between those speakers.

        Re: Experimenting with Low Frequencies

        For loud bass sonic exposure, go to a dragstrip when there is a supercharged ('blown') nitromethane class running--either Funny Car or Top Fuel. There are louder man-made things in the world, but it's a very, very short list.

        It feels as if the sound grabs you by the air in your lungs and gives you a good shaking. Engineering sorts and people who like interesting experiences should definitely go and see the show.

        Re: Experimenting with Low Frequencies

        Interesting that you had to have both windows down. I get this effect in my current car, but only if I have the window down on one side but not the other. I assume its producing a (very low) note in the same was as blowing across the top of a milk bottle does. Having both windows down equally on each side stops the effect (but can then cause complaints of 'too windy' from the children ;-) )

      3. Struggling to find a different name

        Re: Experimenting with Low Frequencies

        Standing at the end of a runway as Concorde takes off over your head (looking straight up the exhaust of four Olympus 593 engines on afterburner) probably has a similar effect.

        It happened to me one day many years ago: I was crossing the BAC airfield at Filton when one of the production aircraft was taking off (not on its maiden flight, as those were well controlled affairs and all local traffic was stopped well in advance). On this day, a routine flight, motorised traffic was stopped from crossing the end of the runway once an aircraft was rolling. I was the only person there, walking across when the warning siren sounded and barriers came down; I looked up to see if anything was coming in to land, and then along to see if anything was taking off. I saw Concorde, head on, coming over the slight rise in the runway. I was halfway across and there was no way I could run fast enough to get clear so I stood still (even Usain Bolt couldn't outrun Concorde on take-off)!

        The pilot must have seen me there in my white lab coat; no extra risk as he'd be off the ground well before reaching me (else he'd also be flying through a chain link fence and end up on the A38 trunk road). The noise from those engines was something I'll always remember - felt more than heard; surprisingly, my hearing wasn't affected (neither short or long term).

    Re: Were previous medical reports wrong?

    I seem to remember reading that some of these folks had brain scans done and they showed signs of damage. Was this damage from previous issues, was it a misdiagnosis, or did they actually psychosomatically cause the damage to themselves? I don't really have any opinion going one way or another as there seems to be so much conflicting information, but I think the question of "why did brain scans show damage?" is a fairly significant one that somebody should be working on.

        Re: Were previous medical reports wrong?

        That paper is not about unreliability in brain scans, it's about unreliability in doing your statistics badly. It was a fun illustration of the need to use multiple comparisons correction when doing mass univariate statistics. That's something that had been around for years when they did that work, however because it reduces your power, people had either not been doing it, or taken to inventing home-brewed "correction" which wasn't worthy of the name (such as using some arbitrary lower p threshold and arbitrary cluster sizes to establish 'significance').

        The problem in a nutshell: outcome of experiments is based on statistical comparisons, standard hypothesis testing. In investigations where you wish to know where something is occurring that means statistical comparisons between images. As usual in hypothesis testing you consider the probability of the measured result given the hypothesis of no difference or effect between groups. However, with images, such as MRI, but also PET, SPECT, you're making that group comparison for each voxel in the image. There are lots of these, while your p values are calculated for single independent comparisons, sets in. With a vengeance To counter that you take your original per-voxel p-values and (equivalently) apply a stricter threshold or adjust them for multiple comparison (reduce them) and apply your original threshold. But what's the appropriate correction? Bonferroni correction says you should divide the p-values by the number of independent comparisons, but the more you do this the more statistical power you use, and adjacent voxels aren't independent, so just using the number of voxels over-corrects.

        Rules of thumb:

        PET and fMRI, look for p<0.05 family wise error correction voxelwise. FWE p<0.05 on cluster sizes can also be used, but cluster forming thresholds should be less than p<0.001 if so (based on Eklund et al. 2016 established false positive rates by using randomised null data), permutation testing preferred.

        Volumetric voxel-based-morphometry (VBM), only voxelwise FWE p<0.05. Cluster based results should not be used. Ashburner and Friston 2000, afraid this one isn't open access, but here's the relevant bit from the "Testing the rate of false positives using randomization" section, "Approximately 5 significant clusters would be expected from the 100 SPMs if the smoothness was stationary. Eighteen significant clusters were found when the total amount of gray matter was not modeled as a confound,and 14 significant clusters were obtained when it was. These tests confirmed that the voxel-based extent statistic should not be used in VBM." (As in the quote, the reason is non-stationary smoothness, which is exactly what it sounds like, cluster size inference assumes the smoothness of the signal is constant across the image, which works for fMRI, but not for VBM / non-linear registration.)

        In general permutation testing is a pretty good alternative to the parametric methods, and can be done in an FWE manner without the assumptions that parametric methods need. Much harder computationally though, and can't necessarily be applied to more complicated experimental designs. Open access and fairly accessible review by Nichols that I was previously unaware of:

        There are alternatives to FWE, such as False Data Rate. While FWE attempts to control the overall probability of false positives, FDR, as the name suggests, controls the rate, the expected proportion of your significant results that are false positives (remember, we're talking about per-voxel comparisons). It provides more statistical power (i.e. reduces false negatives), but people can be wary of it, because it doesn't give you the same 'guarantee' of significance (which of course is not a guarantee anyway).

        And so the JAMA paper on these embassy workers: secondary analyses not multiple comparisons corrected, so ignore. Primary analyses, they did a number of these, one being whole brain volume. Whole brain volume is not a statistical image comparison, it's comparing a single number from each image, which on its own does not have the multiple comparisons issue discussed above. Multiple comparisons reappears though if you compare more things... they do, and use FDR correction on their primary outcomes. What do they find? Significantly smaller white matter volume, but not significantly smaller grey matter volume, and it actually trends in the other direction. Sex is controlled for, just as well as the control group has slightly higher proportion males to females than patient group. For the rest, they pretty much throw the kitchen sink at it, and some of those differences are probably real. Some of the subjects had head injury histories (former military?), they claim that excluding these did not change the results, however while they show some of this in the supplementary (one of the longest I've seen), they don't show it for the white matter volume change. Conclusions? "Significantly lower functional connectivity was observed in the auditory and visuospatial networks in patients compared with controls." You don't have to believe a sonic weapon was involved to believe there are differences here; we're looking at a cohort that reported some phenomenon and comparing to a control group(s), you could equally believe that the volume difference (and connectivity differences) might be associated with suffering long term anxiety, or with a higher vulnerability to mass hysteria or hallucination, or with insecticide exposure as suggested by other posters.

          Correction #2: "To counter that you take your original per-voxel p-values and (equivalently) apply a stricter threshold or adjust them for multiple comparison (reduce them) and apply your original threshold." - obviously when adjusting p-values it's increasing them that's equivalent to applying a stricter (lower) threshold.

      Re: Were previous medical reports wrong?

      And another tech site reported on yet another study that the damage was actually from insecticide used around the grounds of both the American and Canadian embassies.

      I find it hard to believe that the Canadians, who reported the same symptoms, regarded themselves as being in a stressful cold war.

      1. thames

        Re: Were previous medical reports wrong?

        Yes, Canada never bought into the "high tech sonic weapon" story, regarding it as fantasy. As noted in the PS, current Canadian detailed medical investigation points to over use of fumigants to kill mosquitoes in the embassy building and diplomatic staff residences. The fumigants were also detected in the bodies of people affected by the symptoms. The insecticide fumigants are based on on neurotoxins, and so have a direct effect on the nervous system, including the brain.

        At the time fumigants were being used excessively due to panic over Zika virus, which was spreading throughout South America. As a result, embassies were having their diplomatic buildings sprayed as much as five times more frequently than is normal. I suspect the Americans were doing the same in their embassy buildings.

        Canadian researchers also feel that any psychological effects of tension or pressure would have played at best a minor role in the effects seen.

        Any "mass hysteria" that is involved in this seems to be affecting people in Washington who seem to think the Cubans have some unimaginably advanced new high tech weapon and are testing it out on multiple embassies in Havana before presumably using it to engage in world conquest.

              Which, ironically, probably would have never happened if the US were sensible enough not to support and promote a little ostensibly independent invasion of Cuba, which pushed Castro - who was up to that point quite open to coming to some sensible arrangement with the US - directly into the Soviet arms.

              However, that was a fairly long time ago; at this point and for many years the most infamous foreign military base located in Cuba - against Cubans' express will, may I add - is most certainly not Russian.

    Ask your friends if they have ever had a doctor tell them "It's all in your head." At least half, maybe more than 3/4 will say yes and then go on at length about the inappropriate 'diagnosis' and injustice of it all.

    For me it was "you're depressed"; nearly 8 years later it was "that simple test for that metabolic condition you explained to us about came up positive. Congratulations!" For one friend it was "you're exagerating. Why?" After laparoscopic operations on both knees, she walked to top of Mont St. Michel. For another it was a premature birth followed immediately by hysterectomy after she complained for months about problems. For a neighbor's child: "oh it's just a sprain and the kid is making too much of it." Arm was broken in 3 places.

Did all your friend's neighbours suffer from the knees and then got an operation? The key difference, and it's not a small one, is the number of people impacted by similar symptoms.

      Also, doctors saying that "it's in your head" does not mean doctors saying "it's not real", that's pop culture. Psychosomatic symptoms are real, and treated in the best way they can by doctors. It's just not something you can pour antibiotics on.

    "Science" ?

    Sounds more like a coverup than Science. The probability of multiple persons experiencing the same pschosomatic symptons at the same time in the same place are essentially none. There is most likely a comon external cause which a Scientist would investigate without bias or jumping to an unsupported accusatory conclusion.

    Assuming the unknown cause was an intentional act, we ought to be able to agree that the perpetrator conducted a malicious attack, and we ought to think about what the acceptable limits are for the unknown cause, to restrict it's weaponisation.

      I've always thought that it could have been a similar directed energy attack, a few kilowatts carrier at a microwave frequency to power another "Thèremin Thing"

      if the microwave carrier interacts with another microwave carrier, you can have audio/sonic, due 'rusty bolt mixing' but there's also the [pdf 5MB] considers Air-gap/faraday-cage room with cute plastic table & chairs, data jumping techniques ‘covert channels’ badBIOS, Fansmitters, high power infrasound, ultrasound, hypersound.

      IIRC there was a described very high power piezo device transducer to get energy into a spooky diplomatic closed chamber & return data, or simply power bugs, but I seem to remember that was developed by "the good guys"

      surely all spooky premises are continuously monitored from DC to light (and beyond) for any coherent/incoherent energy emanation?

      Unfortunately, you are wrong. Humans are social/tribal/pack creatures, and the phenomena of mass psychosomatic symptoms is well known and frequently documented.

      Why would we make that assumption? There is no evidence to support it.

    Audio is easy.

    If a sonic attack was suspected, it would be simple to detect. The projector would also have to be out in the open in direct line of sight (sound). I'm sure "somebody" at the embassy would have a high resolution camera and a long telephoto lens.

    Given that Cuba is third world, whatever they use to kill critters isn't going to be on the UN approved list. It will also work a treat. I'll side with Occam here and place my bets on insecticide fumes being the likely culprit. Lesson learned and going forward, embassies need to be cautious about any sort of *cide being sprayed. Politically, Cuba has to dislike the US, but the population certainly doesn't mind US currency. Tourism is big business there so sans a fanatic leader being propped up by another nation-state, I doubt that they would go any further than the usual barking about how the world is so unfair to them. "Oh, you want to take a photo of my classic car?, that will be $5 cash, thank you very much."

      Re: Audio is easy.

      When visiting Cuba a couple of years ago I was interested to meet quite a few murricans there as tourists, and $US are quite welcome there.

      Apparently it's a massive PITA for USAians to visit Cuba, because of the restrictions imposed on them by their own government. There are only a few "legitimate" reasons for which you're allowed to go to Cuba, and you have to keep all of your documents/receipts/tickets/etc for 7 years afterwards in case they want to question you about it, as obviously you're some kind of subversive (and they accuse the Cubans of oppressing their own people!). So, most of the murrican tourists simply fly to Canada first, fly to Cuba from there, and never bother telling their own government they've been.

      Yes, you can ask the Cuban immigration people nicely and they won't stamp your passport.

        "Yes, you can ask the Cuban immigration people nicely and they won't stamp your passport."

        The default is they won't stamp your passport and you get there via a flight from some country like Mexico. If you like, they will stamp a separate piece of paper you can keep with you as proof of proper entry and a souvenir. Just don't keep it in your passport or the ink might transfer.

    Were it really a sonic weapon, how did they ensure only foreign diplomatic staff would be affected ?

    Climate change

    You can add the climate emergency to the mass hysteria list. A new world science based on computer models programmed for free by post grads who know nothing about computer science using data that has to be massaged before it can be used. Any form of conclusion relies on data 100s of years old (short-term changes are meaningless) most of which does not exist and must be filtered and modified for "good" data - so much for controlled experiments.

    Before the climate crisis no one was interested in climate science now 18 year olds want to study it in order to save the world. So most of these scientists who are filtering data and creating the computer models are climate change believers on a crusade to save the earth.

    All you need to add is the population on mass simply repeating what everyone else is saying and calling that "understanding science" and some grown men crying because a penguin doesn't have to suffer as cold a winter as usual and you have all the ingredients of mass hysteria

    This sounds very much like something that was claimed to be going on waaaay back in the 80s? 70s? Might not have been Cuba though - can't remember
