What a weird, rambling article. I read the whole thing and I'm really not sure what point they were trying to make. Two ultrasonic signals can interfere to produce lower wavelength sound? That's kind of obvious to anyone who has studied signals...
- alexandercrohde 9y agoI agree it was poorly written. I believe the intent was to say: A) We have recording from Cuba, therefore there's proof of ultrasonic noise. B) This noise we have is in the audible spectrum, but we have reason to suspect it's from the interaction of two ultrasonic frequencies that together produce a very whiney audible frequency C) Ultrasonic noise can be used for spying and voice-injection, so there's a potential motive for the US to use such technology at an embassy.
