Electrophysiological measures of binaural interaction in cochlear implantees

Abstract Electrophysiological measures that can be used to objectively evaluate binaural interaction in cochlear implantees include the binaural interaction component (BIC) and an evoked potential analog of the ‘masking-level difference’ (MLD). Results from normal listeners show that cortical auditory-evoked responses obtained using these methods can be used to measure binaural processing. Preliminary data from three sequentially implanted adults are presented.
