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.

    Canada does, it's just suppressed by organizations because of political correctness.

    So if the data is suppressed (and your article confirms it is not collected at all in some jurisdictions), how do you know there is a trend of gun violence specifically in poor black neighbourhoods, but not in other racial categories? Personally I think Canada likely has similar, if less inflamed, issues as the US in terms of racial disparity and over-representation in criminal statistics simply because CA/US cultures aren't that far apart. However I find claims of specific trends lack credibility without actual data to back it up. I would love if we had actual public data on this so we could try to address issues that might exist.

    Or you can simply pay attention to the media, which paint a picture of what's happening too.

    No, there is too much bias in media. I take trends in media as trends in what people are interested in at the time. When I see an uptick in articles about police killing unarmed black civilians, I don't assume this is suddenly happening more often, only that people are suddenly more interested in those stories.
