cuba noise sounds like cicadas or other noisy insects
many moons ago in india one outside my window turned itself up to eleven
middle of the night, no way to sleep, also impossible to find the little bugger and shoo it away
We almost wanted to feel sorry for Equifax, were it not for the fact that the credit biz takes to IT security like a duck to an acid bath. After a brutal few weeks under the spotlight, on Wednesday night it suffered another hacking scare. When's it going to end? Visitors to one of Equifax's customer support webpages couldn't …
Yes. Once had a girlfriend with a chameleon. That of course was silent, but its food could make quite some noise :) somehow I doubt this is the sonic weapon you are looking for...
As a side note: a few decades back there was a wave of sicknesses after consuming a certain popular soft drink in Germany and the Netherlands and possibly elsewhere. They never found anything wrong with the product itself, but concluded it was a non-cebo effect (nasty version of placebo), it was mostly among teenagers (1999?). I'm not saying this is what happened in Cuba, but it is one of the possible (maybe quite unlikely) explanations. Maybe combine this effect with really targeting one or two persons, and then the rest of the group will follow suite...
Naah,
My guess is it was just someone trying to play the violin on the wrong side of the bridge. Or slightly more seriously, a few really badly configured baby monitors or network-over-mains in the embassy electrics doing bad things to the the tube lighting. Someone should stick an oscilloscope on the live wire and start turning things off one by one.
It's probably some random electronics making the noise, like you said. The recording sounds an awful lot like a dodgy switched-mode power supply...
Combine this with some classic mass hysteria - of which there are many, many historic examples - and you have a winner.
You'd think people affected might remember hearing that sound being blasted at them, but apparently only a few do, so I'm not sure how that, and the unattributed nature of the recording's origin, justify all the certainty under the "Sonic Weapon REVEALED!" headlines. ISTM that a rather more plausible explanation is in this Guardian article - but then that wouldn't fit in with the current Adminstration's anti-Cuba stance, would it?
Cure (ISBN: 9780385348157) has a reference to a study where a nocebo was correlated with small doses of a toxic drug and was then sufficient to cause death when applied on its own (in animals). This is interesting since it implies the pathway doesn't depend on reasoning (as supported by placebos being effective even when the subject knows its a placebo)
Won't stop overuse of Slurpy-Analytics or websites hosting Facebook & Google widgets which phone home with juicy info even on non-users...
"A third-party analytics provider, which measures and reports the performance of sites, was used by Equifax - it was pwned it seems."
"By switching up some of the parameters in the GET request, and supplying a stranger's valid T-Mobile US number, he could pull up their account details, such as their email address and handset's unique IMEI number."
This, of course, is more 'hacking' than what weev did against AT&T (he just enumerated id's in the request if I'm not mistaken). And he got thrown in jail for it.

Yes, Weev just added an additional number to a URL and AT&T's system kicked back a bunch of info. It was more of a case of an unpublished (and unsecured) web page not true hacking. I have all sorts of pages that aren't linked anywhere that I use to put semi-private photo galleries, work in progress that isn't particularly sensitive etc. If somebody can guess the page name, they can have a look at my photos of a Wishbone Ash show or the next iteration of my web site. I even have reference text files that I maintain for writing articles. Boring stuff in the main other than the Wishbone Ash photos. Go see them if they're in town. The band is incredibly tight and classic rock is timeless.
The legal system is clogged up with older people that didn't grow up with computers, don't want to learn them, yet are tasked with passing judgement over what is and isn't malicious hacking. Weev doesn't help himself by generally being unpleasant.
Some courier companies used to use this technique. If the tracking number looks like it might be a sequential number, rather than a hashed value, incrementing or decrementing by one would often give details of someone else's delivery (I kid you not). They didn't even use a checksum to guard against legitimate typos. One one would hope that this kind of thing is a thing of the past.
Guess no one has had a copy of "The Big Brother Game" by Scott French, August 1976 [didn't someone reference Wishbone Ash and then old]
Thought it had to do with the ear being non-linear not the air - Fastl H., Zwicker E. (2007) The Ear’s Own Nonlinear Distortion. In: Psychoacoustics. Springer, Berlin, Heidelberg
Interesting to see that the Japanese thought the technology infeasible in the 1980's
So on the wiki, along with a bit of confusion about the value of the entry ....
Sound from ultrasound - Parametric array
Since the early 1960s, researchers have been experimenting with creating directive low-frequency sound from nonlinear interaction of an aimed beam of ultrasound waves produced by a parametric array using heterodyning.
Ultrasound has much shorter wavelengths than audible sound, so that it propagates in a much narrower beam than any normal loudspeaker system using audio frequencies. Most of the work was performed in liquids (for underwater sound use).
The first modern device for air acoustic use was created in 1998,[1] and is now known by the trademark name "Audio Spotlight", a term first coined in 1983 by the Japanese researchers[2] who abandoned the technology as infeasible in the mid-1980s.
A transducer can be made to project a narrow beam of modulated ultrasound that is powerful enough, at 100 to 110 dBSPL, to substantially change the speed of sound in the air that it passes through.
The air within the beam behaves nonlinearly and extracts the modulation signal from the ultrasound, resulting in sound that can be heard only along the path of the beam, or that appears to radiate from any surface that the beam strikes.
This technology allows a beam of sound to be projected over a long distance to be heard only in a small well-defined area;[citation needed] a listener outside the beam hears nothing.
This effect cannot be achieved with conventional loudspeakers, because sound at audible frequencies cannot be focused into such a narrow beam.[citation needed]
Big organisations routinely use and force their website users to accept loads of scripts written / hosted and delivered by a host of much smaller 3rd party outfits often of quite dubious provenance. They seem to do this because it's easier / cheaper than trying to either do the thing the script is suppose to do themselves (which is often totally useless to the site visitor) and can then dodge responsibility and blame the 3rd party when things go wrong. I can't be the only one fed up with this kind of stuff.
