I believe the author of the message quoted below should have stated that, according to the paper cited, "ultrasonic hearing" IS cochlear. The hypothesis tested, and not rejected, was that the audio signal is de-modulated (off the ultrasonic carrier) via bone properties and thence detected via normal auditory processes. The question remaining is whether or not an auditory perception can be elicited via ultrasonic (or any other) stimuli not delivered via cochlear implant-like devices in anyone (synesthetes notwithstanding) with a clear inability to transduce audio-frequency vibrations via the cochlea.
