Well, if I might comment (shortly) on this one for I am (too) finding
this a little contradictory, _just_ with respect to what had been stated
above : hence, just the fact that there are "acoustic differences ...
between groups, discontinuities, silences ... [due to] temporal
variation of acoustic energy" refers to it already being physically
(sort of) 'organized in time' in a way providing a certain potentiality
to being perceived (just) as such ; so there is something like a
'conditional relation' between the physical and the psychological
'entities' (-- are they really more 'entire' in the psychological domain
...?).

Another point concerns

>sounds coming from physically different sources
[with the description as to state being a physical one ...]
-- what, given the age of choral (responsorial) formations (in human art
at least since the 5th c. bc), shouldn't yet be so 'unusual' in
gregarious animals, either ...
