对于具有残余低频声学听力的耳聋个体，联合使用人工耳蜗（CI）和助听器（HA）通常比单独使用任何一种设备提供更好的言语理解。由于粗糙的频谱分辨率，CI不提供有助于理解声调语言（如汉语普通话）的基频（F0）信息。HA可以提供F0的良好表示，并且取决于辅助听觉的范围，可以提供第一和第二共振峰（F1和F2）信息。在这项研究中，普通话的声调，元音，辅音识别安静和噪声中测量了12名成年人说普通话的双峰听众与CI，只有和CI+HA。在噪音中，CI+HA的音调识别明显更好，但在安静中则不然。元音识别与CI+HA在安静，但不是在噪声中显着更好。在安静或噪声环境中，CI-单独和CI+HA之间的辅音识别没有显著差异。双峰效益的范围很广，在某些测试和条件下，改善往往超过20个百分点。将双峰益处与CI受试者在250和2000 Hz之间的HA辅助纯音平均（PTA）阈值进行比较;受试者被分为两组：“较好”PTA（<50 dB HL）或“较差”PTA（>50 dB HL）。双峰效益组间差异显着只有辅音识别。在安静的音调识别的双峰效益显着相关的CI经验，这表明双峰CI用户学会更好地结合联合收割机的低频频谱时间信息从声学听觉与时间包络信息从电听觉。鉴于本研究的受试者数量较少（n = 12），对中国双峰听众的进一步研究可能会提供更多关于声学和电听觉对音调语言感知的贡献的信息。
For deaf individuals with residual low-frequency acoustic hearing, combined use of a cochlear implant (CI) and hearing aid (HA) typically provides better speech understanding than with either device alone. Because of coarse spectral resolution, CIs do not provide fundamental frequency (F0) information that contributes to understanding of tonal languages such as Mandarin Chinese. The HA can provide good representation of F0 and, depending on the range of aided acoustic hearing, first and second formant (F1 and F2) information. In this study, Mandarin tone, vowel, and consonant recognition in quiet and noise was measured in 12 adult Mandarin-speaking bimodal listeners with the CI-only and with the CI+HA. Tone recognition was significantly better with the CI+HA in noise, but not in quiet. Vowel recognition was significantly better with the CI+HA in quiet, but not in noise. There was no significant difference in consonant recognition between the CI-only and the CI+HA in quiet or in noise. There was a wide range in bimodal benefit, with improvements often greater than 20 percentage points in some tests and conditions. The bimodal benefit was compared to CI subjects’ HA-aided pure-tone average (PTA) thresholds between 250 and 2000 Hz; subjects were divided into two groups: “better” PTA (<50 dB HL) or “poorer” PTA (>50 dB HL). The bimodal benefit differed significantly between groups only for consonant recognition. The bimodal benefit for tone recognition in quiet was significantly correlated with CI experience, suggesting that bimodal CI users learn to better combine low-frequency spectro-temporal information from acoustic hearing with temporal envelope information from electric hearing. Given the small number of subjects in this study (n = 12), further research with Chinese bimodal listeners may provide more information regarding the contribution of acoustic and electric hearing to tonal language perception.
