At one time the USA discovered that the Soviets were bombarding their Moscow embassy with radio waves. Decades later it was learned that a genius names Theremin had built a device that acted as both microphone and transmitter, when bombarded with a specific frequency of radio waves.

There has been some writing on how it used wave guide effects to transmit, but not so much on the microphone part. Some of you may know that many speakers can be wired up as microphones. One wonders whether a device intended to be a microphone, might in some circumstances act as a speaker as well.

If the Cubans are following an evolutionary path from the device concealed in the Great Seal in the 50's then one could easily imagine something built into the structure of the building itself that is accidentally generating sound energy.

As a thought experiment, imagine that you could build a window frame that would pick up sound from inside a room, shift it to an inaudible frequency and then emit that sound. Furthermore, what if a double pane window intended to block sound from leaving the room, had a pickup attached to the inner glass pane and emitted the high frequency sound from the outer pane so that an external laser could pick it up. Then further imagine that the window was installed wrong way around so that the constant street noise was broadcasting high frequency sounds into the building.

I expect that the Russians don't do this stuff anymore because they get better results from HUMINT, especially deep cover agents.

That is the furthest idea from my conceptual model of what this all might be. I don't think any of this is accidental. I think deliberate harm is being done, and that willful animosity has permitted the rationale that U.S. officials represent a population of human test subjects, as expendable resources, for a weapon with unknown neurological effects to be used against aggressive enemy combatants.

I think it's a directed energy weapon.

I think kinetic energy is being applied in a novel way, such that patterns of constructive interference are created by alligning harmonic waveforms so that their intersection creates high-signal regions with deleterious effects for biological tissue within said region.

Much in the way electromagnetic directed-energy-weapons can be combined and focused to achieve greater effect, either ultrasound or infra-sound is being used as a kinetic analog with similar results. This is not "The Brown Sound" but something worse.
