Keynote lecture: objective measures

The number of young children receiving cochlear implants for management of profound hearing loss is increasing world-wide. In these children, objective measures play a vital role both before and after implantation. They have the capability to assess the degree of hearing loss, guide the selection of the ear and patient for implantation, and provide valuable assistance with the tuning of the device in the difficult-to-test and very young children. There is considerable opportunity for further development of these techniques in the future and, in particular, for accessing central perception and cognition.
