RERUN 3 AM5

[apollolux]

The frequency of the ultrasonic sub is in the range that thoughts are in. [ ... ] if one were to train their hearing over time.. I think hearing others thoughts could be possible.

Crowded room or not, I think the thing stopping that from happening is all the fluids, skull, and scalp encasing the brain, kind of like a soundproofed room, so whatever thought waves do escape are so filtered and muffled that they're completely unintelligible to people. This is probably why electronic brainwave readers attach probes directly to the scalp, to be as close as physically possible to the brain without opening up the skull or other invasive procedures.
