UM-Bot Posted October 14, 2017 #1 Share Posted October 14, 2017 A clip of the high-pitched sound that US diplomats have been hearing in Cuba has been uploaded online. http://www.unexplained-mysteries.com/news/312460/cuba-sonic-weapon-audio-recording-released 1 Link to comment Share on other sites More sharing options...
Space Commander Travis Posted October 14, 2017 #2 Share Posted October 14, 2017 Sounds like the chirping of crickets. Or a monitor whose cable doesn't quite fit quite right and emits that annoying buzzy sort of sound. Anyway, I was expecting something along the lines of a Bass Cannon or something.

acute Posted October 14, 2017 #3 Share Posted October 14, 2017 This recording has to be fake. We can now hear inaudible sounds via the medium of YouTube! 2 Link to comment Share on other sites More sharing options...

3.0 Posted October 15, 2017 #7 Share Posted October 15, 2017 This is a trick post? To see who listens to the sound? 1 Link to comment Share on other sites More sharing options...
highdesert50 Posted October 15, 2017 #8 Share Posted October 15, 2017 We are hearing a recording that has been optimized for our human hearing range of about 20Hz-20kHz by computer hardware and software and not necessarily what may have occurred on site. We may even be, for example, hearing submultiples of the fundamental driving frequency. Further, the amplitudes, or intensity, of the sound or sounds may not be accurately represented in the recording. More definitive might have been using a trusted instrument having both more sensitive hearing and a far greater frequency response, a pet cat. 1 Link to comment Share on other sites More sharing options...
Sir Smoke aLot Posted October 15, 2017 #9 Share Posted October 15, 2017 If i got this right, Castro made Cuba into worlds leader when it comes to things like this. Multi billion researches of worlds best scientists in USA or EU and even Russia or China, they could not manage to manipulate frequencies like Cubans did. It's a shame Where did the money go!

paperdyer Posted October 16, 2017 #10 Share Posted October 16, 2017 Considering I had to turn my laptop volume up all the way, how low was the original recording? It does sound like a squeal from a bad cable connection, but higher. Nothing I'd like to hear more of. Link to comment Share on other sites More sharing options...
Dhem Posted November 27, 2017 #11 Share Posted November 27, 2017 I stumbled upon this thread while doing some unrelated research. The sound intrigued me enough to download it and take a look at the spectrogram. Here's the overall view of the left channel: Link to comment Share on other sites More sharing options...
Dhem Posted November 27, 2017 #12 Share Posted November 27, 2017 Next I was going to add the zoomed in area of interest from 6kHz to 8kHz, but: "You are only allowed to upload 245.76kb." lol, guess not. Link to comment Share on other sites More sharing options...
bison Posted November 27, 2017 #13 Share Posted November 27, 2017 (edited) The article refers to this as a 'high pitched' sound, but a low frequency droning is also apparent. It's rather like the sound bees make with the beating of their wings. At high enough volume, this sound could very well be irritating, to the point of depriving someone of sleep. Many of the other symptoms described could ensue from that insomnia, if it kept up for a long enough period of time, say days, or weeks. Why this sound should have been directed at American diplomats in Cuba is not clear. The Cuban government has desired to re-establish diplomatic relations with the United States, and has cooperated in the investigation of the matter. They allowed the FBI to come in to study the situation. I haven't heard that the Bureau reached any productive conclusions. Perhaps the Cubans were not involved, and the source of this sound remains a mystery. Edited November 27, 2017 by bison Link to comment Share on other sites More sharing options...
