> I forget all the details but it it nearly placed the sound in your head. Keywords on that is "voice to skull" - though what I recall, the way it was done was by layering the audio over an ultrasonic carrier wave that could be focused on the targeted listener, and the carrier would be stripped away by the listener's skull, leaving the audio behind which would be heard via bone-conduction. I'm not saying what you describe isn't a method either - it sounds plausible, and I haven't kept up with all of the developments in the technology. None, though, was as interesting ("scary"?) as the microwave transmission method direct to the brain/neurons...
