双侧耳蜗植入体（CI）改善了语音清晰度，背景噪声中的语音感知以及安静和嘈杂情况下的声音定位。然而，目前还不清楚这些优点是否本质上导致双耳整合的声学刺激从每只耳朵。在这项研究中，我们调查了双耳整合的有效性，通过双边CI放置双耳听力测试和主观听觉感知评估。一名61岁的双侧CI受试者接受了以下四项测试：噪声中的日本听力测试（HINT-J）、双耳分听测试（DLT）、快速交替言语感知（RASP）测试和主观听觉感知评估。双侧CI的HINT-J评分显著高于单侧CI。然而，DLT和RASP测试显示了相互矛盾的结果。主观听觉评价显示双侧听觉的印象活跃而明亮，与单侧听觉相比，双侧听觉的印象也嘈杂而强烈。本研究的结果显示，双边CI改善语音感知在背景噪音和改善听觉印象，虽然双边整合能力没有改善。这可能是因为在DLT和RASP测试中，患者需要将来自双耳的联合收割机信息合并为单一感知。在未来的研究中应收集和分析更多的纵向数据，以评估双侧CI的长期影响。
Bilateral Cochlear implants (CIs) improved speech intelligibility, speech perception in background noise, and sound localization in quiet and noisy situations. However, it is unclear whether these advantages essentially result in binaural integration of acoustic stimuli from each ear. In this study, we investigated the effectiveness of binaural integration by bilateral CIs placement using binaural hearing tests and subjective auditory perceptual assessment. A 61-year-old bilateral CIs subject underwent the following four tests: the Japanese Hearing in Noise Test (HINT-J), the dichotic listening test (DLT), the Rapidly Alternating Speech Perception (RASP) test, and subjective auditory perceptual assessment. The HINT-J score was significantly higher for bilateral CIs than for a unilateral CI. However, DLT and the RASP test revealed contradictory results. Subjective auditory perceptual assessment revealed active and bright impressions for bilateral hearing, which were also noisy and strong compared with those for unilateral hearing. The results of this study revealed that bilateral CIs improved speech perception in background noise and an improved auditory impression, although the bilateral integration abilities were not improved. This was probably because the patient was required to combine information from the two ears into a single perception in DLT and the RASP test. More longitudinal data should be collected and analyzed in future studies to evaluate the long-term effects of bilateral CIs.
