DESCRIPTION:Speaker: George Zweig\nAbstract: Information in sound is coded 
 by the cochlea into a form appropriate for analysis by the central nervous
  system. The mechanics of the cochlea initiates the coding process by prov
 iding a distributed\, active (energy producing)\, nonlinear medium in whic
 h forward traveling waves set up by sound compete for amplification and ne
 ural representation. Measurements of traveling waves are used to deduce th
 e equation governing their propagation. Forward traveling waves are partia
 lly reflected from random mechanical inhomogeneities\, creating backward t
 raveling waves. What is not reflected at the stapes appears as sound in th
 e ear canal. Such otoacoustic emissions\, when measured\, enable both a te
 st of theory\, and an accurate non-invasive determination of the mechanica
 l state of the cochlea during the normal course of hearing.
