研究空间距离和噪声类型对单侧普通话人工耳蜗（CI）使用者和听力正常（NH）受试者句子识别的影响。22名单方面说普通话的CI用户和六名NH听众参与了这项研究。测量三种噪声类型（稳态噪声、言语混串音和音乐）的言语接收阈值。来自普通话言语感知测试的句子直接呈现在听众面前（0°）。噪声来自五个扬声器位置之一：−90°、−45°、0°、+45°和+90°。总体而言，CI性能显着较差，比NH性能的所有空间分离和噪声类型的条件。NH的听众在音乐方面表现最好，在稳定的噪音方面表现最差。CI用户在稳定的噪声中表现最好，在串音中表现最差。噪声位置和噪声类型对性能有显著影响。不同噪声类型对CI使用者的头影效应无显著差异。性能差得多CI比NH的听众为所有的噪声类型和空间分离。噪声类型对单侧CI使用者和NH收听者的影响不同。CI用户的有限光谱分辨率似乎不会影响头部阴影。
To investigate the effects of spatial separation and noise type on sentence recognition by unilateral Mandarin-speaking cochlear implant (CI) users and normal-hearing (NH) listeners. Twenty-two unilateral Mandarin-speaking CI users and six NH listeners participated in this study. Speech reception thresholds were measured for three noise types (steady state noise, speech babble, and music). Sentences from the Mandarin Speech Perception test were presented directly in front of the listener (0°). Noise was presented from one of the five speaker locations: −90°, −45°, 0°, +45°, and +90°. Overall, CI performance was significantly poorer than NH performance for all spatial separation and noise type conditions. NH listeners performed best with music and poorest with steady noise. CI users performed best with steady noise, and poorest with babble. Performance was significantly affected by noise location and noise type. There was no significant difference in head shadow effects among the different noise types for CI users. Performance was much poorer in CI than in NH listeners for all noise types and spatial separations. Noise type differently affected unilateral CI users and NH listeners. The limited spectral resolution in CI users did not appear to affect head shadow.
