The full benefit of bilateral cochlear implants may depend on the unilateral performance with each device, the speech materials, processing ability of the user, and/or the listening environment. In this study, bilateral and unilateral speech performances were evaluated in terms of recognition of phonemes and sentences presented in quiet or in noise. ⋯ The results indicate that subjects who show symmetry in speech recognition performance between implanted ears in general show a large binaural benefit.
