I don't know if it is the same work but I did some consulting for Gary Kendall at Northwestern U once, who was investigating "stereo hearing" and he commented that in the investigation he did, that some people were able to detect an inter-aural difference corresponding to one wl at 200KHz.
Now, in questioning, he explained that was a time difference one detected and NOT a reflection on the bandwidth of ones hearing.
It was his finding that with the equipment of the day (in the early 90's) that a sampling rate of 200KHz was sufficient to capture what we could detect (by monitoring brain waves) if not consciously hear. Some of the hf things seem to involve a brain response but no conscious awareness of it, that is to say you register a sound physiologically but you don't hear it per say. That is different than hearing loss where you don't register the sound or hear it.
Fwiw, to reproduce a square wave well enough that it looks essentially perfect on an oscilloscope, the system needs a bandwidth that extends from about 1/10 to about 10X the fundamental F.
