Issues in Creation of Bio-Compatible Cochlear Signal: Towards a New Generation of Cochlear Prosthetic Devices

A model of a fully functional cochlear prosthesis is presented here, simplified by taking into account only those evolutionary features of natural cochleae that contribute to their functionality. The proposed prosthetic device generates a bio-compatible digital signal which can be fed to the cochlear nerve. Subsequently, analysis of cochlear nerve signals is offered, both natural and artificial. To that end a number of mathematical theorems are formulated, proven, and then used to demonstrate that signals obtained from our prosthetic device are useful towards auditory pattern recognition, audio location, and even speech comprehension, as well as understanding and enjoyment of music
