Speaking as a former acoustical consultant that has worked with both infrasound and ultrasound on a professional level, allow me to admit that I am fucking baffled as to WTF is going on at the Cuban embassy. My efforts to investigate the mechanics of what's going on have been thwarted before they could even begin.
I have no idea what the hell people are talking about. I'm halfway expecting a low-key study to reveal that it was black mold all along and the Cubans let leak something about a "sonic weapon" so it would look like they're cooler than we think, rather than lamer.
Not to say I refuse to believe the Cubans were capable of this. I just am at a total loss to explain what or how they were doing.
