Bimodal hearing benefit for speech recognition with competing voice in cochlear implant subject with normal hearing in contralateral ear
Bimodal hearing benefit for speech recognition with competing voice in cochlear implant subject with normal hearing in contralateral ear
Objectives: This project assessed electroacoustic benefit for speech recognition with a competing talker.
Design: 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.
Results: High-frequency sound did not improve performance, but low-frequency sound did, even when unintelligible and limited to frequencies below 150 Hz.
Conclusions: 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 limited residual hearing.
