The mistake is assuming that sound waves are being used here. You can make the human brain hear sound by transmitting electronic frequencies at it. If someone is transmitting to a satellite using a narrow-band beam that intersects someone’s brain, they’ll be lucky to survive without brain damage from the microwaves alone. At the very least, I would hope that diplomats are being advised by the government to try and record the effect with their phones, to see if it is truly sound-based or if it is actually EM-based transmissions affecting the brain.

I microwaved my skull once with a 0.5 degree beamwidth 15-inch yagi antenna at 1 watt of 2.4 gigahertz once by accident. It was a directional sensation that lasted less than a clock second, as I reflexively snapped around and ripped every wire out of the assembly to kill it with my reptile brain before it killed me. I remember exactly what it felt like, but I can’t say if it triggers hearing or not because it was too brief. The migraine that resulted lasted for hours and I still get sympathetic twinges remembering it.

I’ve also heard stories of a datacenter having a daily failure in a specific rack on weekdays only, that was resolved by moving the satellite dish transmitter next door to point elsewhere than directly through a building.

Combine those two stories and you have a lot more interesting options than just ‘sound’ alone. I hope they’re being investigated.
