AbstractPurpose: The benefits of bilateral cochlear implants (Cls) versus unilateral Cls were evaluated by comparing the Cantonese lexical tone discrimination scores conducted in a quiet environment and against a background noise. Materials and Methods: Four postlingually deafened Cantonese-speaking adults (2 men and 2 women) with bilateral Cls were included in this study. The subjects were their own control in the monaural hearing condition. Both the Cantonese lexical tone stimuli and the speech-weighted background noise were presented at 0° azimuth and at a distance of 1 m from the subject. The speech stimuli, which were maintained at 65 dB sound pressure level, were presented in both a quiet environment and against a background noise at signal to noise ratios (SNRs) of +15, +10, +5, 0, -5, -10, and -15. Results: Against a background noise, the bilateral Cls required +5 dB SNR only to obtain significant scores in discriminating Cantonese lexical tones and to achieve discrimination scores that were comparable to the optimal discrimination scores obtained in quiet. No significant difference in the discrimination scores was observed between binaural and monaural hearing conditions when the tests were conducted in quiet. Conclusions: Our study showed that in the presence of background noise, bilateral Cls were better than unilateral Cls in discriminating Cantonese lexical tones.
