Recordings of the Sounds Heard In the Cuban US Embassy Attacks Released (apnews.com)

New submitter chrissfoot shares a report from The Associated Press: The Associated Press has obtained a recording of what some U.S. Embassy workers heard in Havana in a series of unnerving incidents later deemed to be deliberate attacks. The recording, released Thursday by the AP, is the first disseminated publicly of the many taken in Cuba of mysterious sounds that led investigators initially to suspect a sonic weapon. The recordings themselves are not believed to be dangerous to those who listen. Sound experts and physicians say they know of no sound that can cause physical damage when played for short durations at normal levels through standard equipment like a cellphone or computer. What device produced the original sound remains unknown. Americans affected in Havana reported the sounds hit them at extreme volumes. You can listen to the "Dangerous Sound" here via YouTube.

      Those recordings are likely just intermodulation products. Basically they occur because of how differences in the frequencies used appear as separate frequencies themselves, both from imperfections in how the sound is created, transmitted, and the natural way sound behaves. The actual frequencies used were likely above and perhaps even below what regular audio recording would pick up. For example my cellphone signal has on occasion been picked up on nearby wired phones as audiable clicking, due to the modulation being in the human hearing range, even though the carrier frequency is 3+ orders of magnitude too high to hear.

      I've analyzed the sounds. If you adjust the equalization carefully, clean up the noise, and adjust the playback speed you can make out that it's actually a message spoken in German:

    I'm more inclined to believe that it's another state-actor or else a very, very large criminal enterprise, something on the international scale.

    If a state-actor they want to limit the US and the West generally from bringing Cuba into the fold.

    If it's a large criminal enterprise, it would be because they are using Cuba for some part of their operation that would be identified and shut down if the US were more heavily involved in Cuba.

    There could never be any plausible malicious intent by people in Cuba against U.S. Embassy personnel. There's just no precedent and no motive.

    The Cuban people were NOT indoctrinated for years to view U.S. Government entities as their enemy. There is NO possibility that rogue elements within Cuban society might be doing this 'For Fidel' out of ideological zeal.

    Nope. None of that should even be considered.

    I'm pretty sure they US public has been more thoroughly indoctrinated to view Cuba as the spawn of Satan by the US media than the Cuban government could ever hope to indoctrinate the Cuban people to view the US as a mere 'enemy'. I attribute this largely to the fact that the average Cuban is better educated and generally better informed than the average American.

    The actual sound is very creepy, but its slightly under volume. You may need to adjust your speaker volume. At 3min the tones begin to oscillate a little causing a slightly dizziness. Be careful. https://youtu.be/cyMHZVT91Dw?t=3m5s

    Worked in broadcasting for a lot of years. I knew an engineer who had troubles with his next door neighbors in an apartment building. So, brought home an amplifier, tone generator and a couple of JBL's and set them against the wall, adjoining the neighbors bedroom. Not sure of the freq, 10hz or lower, and cranked it up when he wasn't home. If you put your hands on the wall, you could feel it, but not hear it. I think the neighbors moved out within a few months.

    I agree with you. And a smarter administration would be asking the following questions instead of just assuming "evil Cubans did this 'cause they're commies!"

    Is there a nation that thrives on chaos and disorder in the world, particularly when it is the cause of such chaos and disorder?
    Is there a nation that regards human life so little that it sent agents on a public airline with a radioactive element to kill a dissident and gave no concern to the impact the radioactivity would have on its own agents or the unknowing passengers?
    Is there a nation that would benefit from Cuban-USA relations deteriorating?

    The answer to all of the above is Russia.

    Yep. For starters, we need to make it apply to white people too. Then that number would jump dramatically. Still be dwarfed by other gun deaths, but as I recall most of those are suicides, followed by accidents, followed by intentional murders over personal causes, none of which should qualify,

    All we really know is there have been sonic attacks against both US and Canadian government employees.

    That's jumping to conclusions.
    My SWAG is that it's a CIA product that's to blame, like a high frequency vibrator attached to windows to thwart laser listening, and that with the panes used in Cuba, the unfortunate side effect is that it acts as a speaker element and causes the sound "attacks".

    They could figure that out relatively easily. Also, the effect would be limited to personnel in/near the embassy. Apparently, some attacks have occurred outside the embassy grounds.

    From what I can tell, only in places where the spooks might see reasons to install anti-surveillance equipment, like the domiciles of operatives.

    And, again, it's alleged attacks. Without us having seen any actual evidence for it being attacks, you're begging the question.

    I really just wish that Americans would figure out how to associate government actions with the government, and not condemn the country or people in it for the actions of their government. Your statement that the American public views Cuba as evil is surprising to me, because I don't think that at all. That may happen for some countries, like North Korea where things are a bit more extreme. But Cuba? I don't see it.

    And I sure as hell hope that people in the rest of the world don't judge all Americans based on what our government does and says.

    Sonic weaponry is not new and far from unknown... causing damage isn't even that hard. The question is whether they've perfected making specific targeted changes to a person with this tech.

    For example: I could turn anyone into a mindless pile right now using little more than the pencil on my desk, BUT if I wanted to, instead, slightly change your behavior I'd need a *really fancy pencil ;)

    The sound in the video is fairly similar to a mixture of a tornado siren and some cicadas but the length of the sample is too short.. would be interesting to do some waveform analysis on how the fluctuations change over a much longer period of time. The brain has a way of filtering out a fairly constant "annoying" sound so the fluctuations you can hear in the short segment probably have a fairly calculated variation pattern to continually force the brain's pattern matcher out of sync (while maybe at the same time gaming the matcher to change behavior with parts of the signal that don't change..)

    Hacking the brain is fun! :-D
