You would need to clarify your definitions of "adequate" and "boolean" in
this context before I could comment. However FWIW have a look at some of
the pages on 'hearing' on the 'Audio Misc' site, and perhaps look at some
of the results of Oohashi and others if you are interested in this topic.
It is not clear what their results may mean (if anything!), but they are
quite intriguing as they imply that 'ultrasonic' sic? components may
have
an effect in some circumstances. However the snark may be a boojum...


I thought that Oohashi's work had been pretty much discredited by now.
Certainly no-one seems to have been able to reproduce his results.
