正常人群依赖双侧听觉。相对于单侧听觉,双侧听觉优势如下噪音背景下更佳的言语识别能力更佳的高频信号识别能力及声源定位能力。在同一环境中,双耳听力显然比单耳听力更具优势,不需要特别的注意力就能达到随意畅通的目的。在通常情况下,双耳的“立体声”听力要比单耳的“单声 Normal people rely on bilateral hearing. Relative to the unilateral auditory, bilateral auditory advantages are as follows: better speech recognition ability in the background of noise better high-frequency signal recognition ability and sound source localization ability. In the same environment, binaural hearing apparently has more advantages than monaural hearing and can achieve the goal of free flow without special attention. Under normal circumstances, binaural ”Stereo “ than the single-ear ”mono
