单侧聋患者人工耳蜗植入术后听觉效果及双耳信号匹配的研究

人工耳蜗植入（cochlear implant，CI）是单侧聋患者重新获得双耳听觉（binaural hearing）的重要手段。单侧聋患者CI术后可受益于双耳听觉，改善其声源定位能力及噪声环境中的言语识别能力。目前认为SSD患者人工耳蜗植入术后双耳间电信号与声信号的匹配（match）整合情况可能是术后是否能获得更大双耳优势（binaural benefit）的关键。本项目拟通过对人工耳蜗植入术后患者CI侧声、电信号的性质研究，得出SSD患者双耳声电信号的最佳匹配方式，并将其应用于SSD患者术后人工耳蜗的调试，比较裸耳及采用双耳声电信号最佳匹配模式前后的双耳听觉优势（声源定位能力与噪声呼下的言语识别能力）的差异，及其随时间变化的规律，研究SSD患者CI术后的听觉效果，揭示声电信号匹配在SSD患者听觉康复过程中的重要意义，从而为实现SSD患者的个体化精准治疗提供依据。

Cochlear implant (CI) is an important method for patients with unilateral deafness to regain binaural hearing. Patients with unilateral deafness can benefit from binaural hearing, improve their acoustic source localization ability and speech recognition ability in noise environment. At present, it is believed that the integration of the two interear electrical signals and acoustic signals after cochlear implantation in SSD patients may be the key to the binaural benefit. This project is based on sound after cochlear implantation in patients with CI side, and study the nature of electrical signals, it is concluded that the best match of SSD patients binaural sound signal, and is applied to the SSD patients with postoperative cochlear debugging, naked ears and adopt the binaural sound signal patterns before and after the best of both ears auditory advantage (sound source localization and noise under the call of a speech recognition ability), and the law of change over time, the SSD CI patients with postoperative hearing effect, reveal the acoustic signals matching in the important value of SSD patients with auditory rehabilitation process, thus provide a basis for the realization of individualized precision of SSD patients treatment.
