The early auditory evoked responses have been studied in bilaterally hearing cats, and in animals with hereditary unilateral anacusis. Cross-over stimulation of the hearing ear occurs at an interaural attenuation of 50--50 dB, and all six waves of the responsare present at supra-threshold stimulus levels.
