Members philboking Posted October 14, 2017 Members Share Posted October 14, 2017 This is no worse than what I hear every day at work from the CNC mills cutting plastic next door to the lab (on those very rare occasions I pull out my earplugs). I suspect this sound is the result of two or more ultrasound beams that have enough SPL to cause heterodyne mixing in the air. Our own government has done research on similar things. I don't know whether infrasound is hazardous ( I suspect not, else EDM subwoofer manufacturers would have serious liability problems.) But high intensity ultrasound is definitely dangerous - it can cause brain aneurisms and other serious problems. Link to comment Share on other sites More sharing options...

Phil O'Keefe Posted October 16, 2017 Share Posted October 16, 2017 I've been following this story with some interest. Honestly I have no idea what is causing the sound, or what has made it (assumedly it is the cause...) so dangerous and debilitating to the US embassy personnel.

Our own government has done research on similar things. I'm not certain, so please don't take this as gospel, but I thought they had ruled that out? I'm pretty sure I read that somewhere... I can't remember where it was ATM though. Link to comment Share on other sites More sharing options...

Srsly though you might have a point although I think anything as specific as American diplomats in Cuba is bound to be a cocktail of tech. Link to comment Share on other sites More sharing options...
Phil O'Keefe Posted October 17, 2017 Share Posted October 17, 2017 FWIW, I've heard it twice now - once on the TV news, and now once in this thread. I've noticed no negative effects... which leads me to believe that there is some other component to this besides what they recorded that caused the effects. But to be safe, I wouldn't recommend listening to it for long periods of time. Link to comment Share on other sites More sharing options...

Members 1001gear Posted October 28, 2017 Author Members Share Posted October 28, 2017 Speaking of Ancient Aliens, the Discovery Channel was running a show on advanced weapons or something and mentioned LRADs; Long Range Acoustic Device I believe. Old tech it seems but some of the symptoms mentioned are consistent with the diplomat's. https://www.livescience.com/60110-how-sonic-weapon-might-work.html http://time.com/4895066/sonic-weapons-cuba/http://time.com/4895066/sonic-weapons-cuba/ Link to comment Share on other sites More sharing options...
