摘要:

鉴于双侧人工耳蜗(CI)使用者数量不断上升,且以儿童为主,临床上需要高效且可靠的测试来客观评估双耳听力。这些测试对于指导双侧人工耳蜗的设置以优化双耳线索的传递至关重要。我们的主要目标是引入一种临床脑电图(EEG)程序,以评估听觉通路中不同阶段的双耳听力功能。先前的研究表明,当脉冲速率超过每秒300个脉冲时,双侧CI使用者的耳间时间差辨别能力显著下降。我们的实验范式利用不同的脉冲速率来客观探索这些极限。该EEG程序面临的一个显著挑战是CI电刺激伪迹引起的干扰。尽管存在这一障碍,CI刺激伪迹的潜在益处往往未被注意到。本文概述了这些经常受到批评的CI伪迹在优化实验设置方面的积极应用。

英文摘要:

Given rising numbers of bilateral cochlear implant (CI) users, predominantly children, there is a clinical need for efficient and reliable tests that can objectively evaluate binaural hearing. These tests are crucial for guiding the setup of bilateral CIs to optimise delivery of binaural cues. Our primary goal is to introduce a clinical electroencephalogram (EEG) procedure to assess binaural hearing function at various stages within the auditory pathway. Previous research demonstrated that bilateral CI users significantly decrease in ability to discriminate interaural time differences when pulse rates exceed 300 pulses per second. Our paradigm utilizes different pulse rates to objectively explore the limits. A notable challenge with this EEG procedure is the interference induced by CI electrical stimulus artefacts. Despite this obstacle, the potential benefits of CI stimulation artefacts often go unnoticed. This paper outlines positive applications of the frequently criticized CI artefacts for optimizing the experiment setup.
