[0002] Cochlear implants are mainly used to help people with severe hearing impairments who cannot be effectively compensated by hearing aids and cannot meet the purpose of hearing and speech communication. For normal hearing people, binaural listening has the advantages of clearer and fuller sound signals than monoaural listening, and improves communication ability and sound source localization in noisy environments.

[0003] Normal people rely on bilateral hearing. Compared with unilateral hearing, the advantages of bilateral hearing include better speech recognition ability in a noisy background, better high-frequency signal recognition ability and sound source localization ability. In the same environment, binaural hearing is obviously more advantageous than monaural hearing, and it can achieve the purpose of free and smooth hearing without special attention. Under normal circumstances, binaural "stereo" hearing is more specific than monaural "mono".
