Abstract : The delay theory of auditory localization is presented which provides a model for attention, location, and recognition wherein the function of the basilar membrane is that of a tapped delay line. It is shown that the same theory may be applied to speech recognition phenomena to show a consistency of the auditory mechanism in the perception and utilization of acoustic information. A new theory of information handling in the nervous system based on photon emission is described. The design and construction of insertion type electrostatic headphones is discussed and performance data given. Localization tests were conducted using the headphones which show that effective aural coupling is achieved. Improvements in devices developed for use in porpoise communication research are presented.
