Appendix 2. Summary of Selected Adult Bilateral Cochlear Implant Studies

Speech recognition Evaluate the benefits of bilateral implant performance in adults. 26 adults bilaterally implanted at 5 US centers. All but 1 of the participants had simultaneous surgeries. CNC words in quiet, CUNY sentences in CCITT noise at individually set SNRs. Speech was presented from the front and noise from the front, 90o from the right or 90o from the left. All stimuli were presented...
