Perhaps I am overreacting . However it is quite a change from the idea of the ear as a passive receiver (i.e. something like a microphone coupled to a spectrum analyser) to the idea of an active, highly unlinear and very complex array of regenerative receivers with feedback controlled gain. It certainly looks that we need to learn how this active system works to be able to progress in our understanding of some still mysterious aspects of human hearing. It also makes some things accepted as cornerstones of acoustics to appear misplaced. For instance, the loudness curves taken with a continuos tone could be quite misleading . When we deal with such complex and well tuned by evolution for the natural surroundings system we have to be very careful in evaluating it by using electronics methods designed first of all for reasonably simple and linear components.
Jim Lesurf in his article, for instance, speculating about a possible implication on a subject of ultrasound components in music as it is very possible that these sounds which we can not hear on their own could affect our perception when we receive them together with the music.
