Sensing the
direction of origin of a sound in space has long been attributed to the delay
between arrival times between the two ears. This, now discredited two
dimensional theory, was put to rest by the observation that a person deaf in
one ear can locate sounds in three dimensional space. We present here a new
theory of sound localization that has the re-quired three dimensional
measurement. It is a theory that interprets the well researched biological
structure of the mammalian cochlea in a new and logical way, which leads to a
deeper understanding of how sound localization functions.
