该项目评估了电声效益的语音识别与竞争的谈话者。使用对侧耳听力正常的人工耳蜗受试者，系统地测量了低通和高通自然声音对语音识别的贡献。高频声音并没有提高性能，但低频声音，即使是难以理解的，并限于低于150赫兹的频率。低频声音有助于分离两个说话者，大概是使用基频提示。将这一发现外推到常规人工耳蜗植入用户可能表明，在对侧耳上使用助听器将提高性能，即使残余听力非常有限。
This project assessed electroacoustic benefit for speech recognition with a competing talker. Using a cochlear implant subject with normal hearing in the contralateral ear, the contribution of low-pass and high-pass natural sound to speech recognition was systematically measured. High-frequency sound did not improve performance, but low-frequency sound did, even when unintelligible and limited to frequencies below 150 Hz. The low-frequency sound assists separation of the two talkers, presumably using the fundamental frequency cue. Extrapolating this finding to regular cochlear implant users may suggest that using a hearing aid on the contralateral ear will improve performance, even with very limited residual hearing.
