Re: Implicit human echolocation

Ah! - thanks - I thought it was a language thing. In fact, I draw no
substantive distinction between the reception of signals and the
interpretation. For example, in respect of pinnae effects, direction is
encoded as spectral modifications, but what is heard is direction.

Any discussion about how we experience sounds immediately reveals the
of a consistent vocabulary. Each author uses words as they see fit. One
such words as detection, awareness, decoding, perception,
significance, cognition, and so on. Similarly, one has theory, model,
heuristic, concept, and so on. When I was doing a review of the
I was constantly struck by the difficulty of language.

To really understand the problem of language, I very strongly recommend
Deutscher's book, The Unfolding of Language. An Evolutionary Tour of
Mankind's Greatest Invention.

Now back to the discussion of echolocation. I distinguish between
(perception) something and giving it a (interpretation) meaning. Most
everyone can hear a spectral difference of a modest boost in low
background noise, but few can translate what that perception into a
sense of
distance to a wall.
