SNRs for left ITC (for an acoustic-hearing ear in a SSD-CI case, dotted line) and BTE (for a CI ear in an SSD or BI-CI case, solid black line for the right ear and dashed black line for the left ear) microphones using HRIRs for target speech at 70° and SSN at 290° (Fig. 1). The SNR was 0 dB before HRIR filtering. The solid gray line represents the modeled effect of performance asymmetry, calculated by subtracting 10 dB from the right BTE microphone response to simulate poorer speech-recognition performance in that ear. BI-CI = bilateral cochlear implant; SSD-CI = single-sided deafness cochlear implant; HRIR = head-related impulse response; ITC = in-the-canal; SNR = signal-to-noise ratio; SSN = speech-shaped noise.
