What Kevin states is not the only problem with our knowledge of the auditory system. In: 1289 Discrimination of surface-structured targets by the echolocating bat: Myotis myotis during flight * J. Habersetzer; B. Vogler JCOPA 1983 152( ) 275-282 [JOURNAL OF COMPARATIVE PHYSIOLOGY A} PDFavailable from me Habersetzer shows that a bat, Myotis myotis , is able to distinguish two objects with differences of only about 1/100 of a wavelegth. Not what we know about detection.possibilities. There is a lot of "stuff" we do not understand.
