摘要 综述听觉系统声源定位的机制及声源定位测试的研究现状。目前,听觉系统对于声音在双耳间形成的特定信号来辨识方向性的机制已研究得较成熟,但听觉中枢如何整合双耳间信号特性来定位的机制尚不明白。研究表明,大部分听障患者在经过听力干预后的声源定位能力都有不同程度的提高,但是使用双侧人工耳蜗或结合使用人工耳蜗和助听器的患者的声源定位能力较单侧使用耳蜗的患者好。 Mechanisms of the auditory system and current research status related to sound localization are reviewed.At present, the mechanism of sound localization by the auditory system using binaural auditory information is very clear,but the neural mechanisms of binaural information processing remain unclear. Some studies indicate that sound localizationability is improved in most hearing impaired people after hearing intervention. Also, sound localization ability is better inpeople with bilateral cochlear implants or one side cochlear implant plus hearing aid on the other side than in people withunilateral cochlear implant only.
