摘要: 目的  探究不同线索下汉语普通话双模式人工耳蜗(bimodal cochlear implant,BIM)使用者在竞争性言语噪声环境中对不同说话者性别和空间线索的利用情况。方法  纳入11例汉语普通话BIM使用者,分别在双模式和单独佩戴人工耳蜗(cochlear implant,CI)时,在4种不同空间竞争性言语噪声下测试言语识别阈(speech reception threshold,SRT)。4种空间竞争性言语噪声环境根据掩蔽噪声的性别和方位的不同分别记为男声中间、女声中间、男声左右和女声左右。其中目标声为正前方向(0°)的一个男声,掩蔽声为2个男声或2个女声,来自正前方(0°)或左右两侧(±90°)。结果  双模式(BIM组)及单独CI助听(CI组)组内和组间言语识别阈差异均无统计学意义(P > 0.05)。BIM组在性别线索、空间线索、性别+空间线索下均获得了掩蔽释放,CI组在性别线索下获得了掩蔽释放,但在空间线索及性别+空间线索下获得了掩蔽干扰,各组在3种线索下掩蔽释放量(masking release,MR)差异均无统计学意义。BIM组与CI组MR在性别线索及空间线索下差异均无统计学意义,在性别+空间线索下,BIM组与CI组差异有统计学意义(P =0.013)。结论  汉语普通话双模式使用者可利用性别线索及空间线索分离竞争性噪声,但双模式和单独CI助听条件下利用性别和空间线索的能力差异均无统计学意义,双模式助听对性别+空间线索利用能力优于单独人工耳蜗助听。

Abstract: Objective  To investigate the utilization of competitive speech by standard Chinese bimodal cochlear implant (BIM) users under  talker sex and spatial.Methods  The speech reception thresholds (SRT) of 11 standard Chinese BIM users were tested under 4 different spatial competitive speech noises. The four spatial competitive speech noise environments were recorded as middle male voice, middle female voice, two sides male voice and two sides female voice according to the gender and orientation of the masked noise. Subjects were assessed with BIM and cochlear implantation (CI) alone hearing assistance. The target sound is one male voice directly in front (0°), and the masking sound is two male or two female voices, coming from separately directly in front (0°) or from both sides (±90°).Results  There was no significant difference in SRT between the two groups (P> 0.05). The BIM group obtained masking release (MR) under talker sex cues, spatial cues, and talker sex+spatial cues, while the CI group obtained MR under talker sex, but masking inhibition under spatial cues and talker sex + spatial cues. There were no significant differences in MR between the three cues. There was no significant difference in MR between BIM group and CI group under talker sex cues and spatial cues, but there was difference between BIM group and CI group under talker sex+spatial cue (P= 0.013).Conclusions  Standard Chinese BIM users can use talker sex cues and spatial cues to separate competitive noise, but there is no significant difference in the ability to use talker sex and spatial cues between BIM and CI alone hearing aid, and the ability to use talker sex + spatial cues under BIM is better than that of cochlear alone hearing aid.
