Hi Chuck,
Well, clearly, we cannot perceive frequencies beyond those that our hardware is capable of conveying to our brains. Other animals with different hardware perceive a different range of frequencies. Some animals (e.g., bats) even have auditory perceptual abilities we can only replicate with the aid of advanced technology.
Depends on what you mean by "percieve". Bass frequencies below what we are supposed to be able to hear raise our blood pressure, pulse, and adrenaline levels, kind of like a scary movie would.
I don't know if that's quite what you meant, though.

He might be referring to the studies that found that hearing perfect intervals raised endorphin levels by a miniscule amount in the subjects, which supports the theory that we are "hard-wired" to perceive music in a certain way.
