Seven subjects participated in a comparison of the normal (N) and noise suppression (S) settings on the Spectra 22 speech processor of the NucleusTM 22-channel cochlear implant system. Speech recognition performance on the Consonant-Vowel Nucleus-Consonant (CNC) Word Test presented in quiet and on the CUNY Sentence Test presented at two signal-to-babble ratios (SBRs) was analyzed for both settings. Group data revealed no significant difference in performance between the N and S settings for either monosyllabic words in quiet or sentences presented in background babble.
