大多数最近植入的人工耳蜗植入患者可能会从植入物对侧耳朵中的助听器中受益。当患者联合收割机电和声刺激相结合时，安静时的单词识别和噪音时的句子识别显著增加。一些研究表明，导致性能水平提高的声学信息主要存在于语音基频的频率区域中，例如男性语音的125 Hz。最近的研究表明，这些信息通过提高词汇边界或单词起始的识别来帮助噪声中的语音识别。在某些噪声环境中，植入双侧植入物的患者可以达到与联合收割机电和声刺激患者相似的性能水平。接受过听力保留手术、接受人工耳蜗电刺激、植入耳和未植入耳均具有低频听力的患者，在高噪声环境中表现最佳。
The majority of recently implanted, cochlear implant patients can potentially benefit from a hearing aid in the ear contralateral to the implant. When patients combine electric and acoustic stimulation, word recognition in quiet and sentence recognition in noise increase significantly. Several studies suggest that the acoustic information that leads to the increased level of performance resides mostly in the frequency region of the voice fundamental, e.g. 125 Hz for a male voice. Recent studies suggest that this information aids speech recognition in noise by improving the recognition of lexical boundaries or word onsets. In some noise environments, patients with bilateral implants can achieve similar levels of performance as patients who combine electric and acoustic stimulation. Patients who have undergone hearing preservation surgery, and who have electric stimulation from a cochlear implant and who have low-frequency hearing in both the implanted and not-implanted ears, achieve the best performance in a high noise environment.
