Measuring binaural fusion can be challenging, especially with bilateral cochlear implant (CI) users. This study validated a technique of using unilateral stimulation to create a reference for measuring fusion. Seven bilateral CI users listened to stimuli randomly presented to the right, left, or both ears. Participants indicated the size, number, and location of the resulting image(s) they perceived. The participants had largely unitary, punctate percepts that were lateralized to the stimulated ear for unilateral stimuli. The image was centered but more diffuse when the stimuli were presented bilaterally. The results suggest unilateral stimuli can provide a reference for binaural fusion.
测量双耳融合可能具有挑战性,尤其是对于双侧人工耳蜗(CI)使用者而言。本研究验证了一种使用单侧刺激来创建测量融合参考的技术。七名双侧CI使用者聆听随机呈现给右耳、左耳或双耳的刺激。参与者指出他们所感知到的图像的大小、数量和位置。对于单侧刺激,参与者大多具有单一、点状的感知,且偏向受刺激的耳朵。当双侧呈现刺激时,图像居中但更弥散。结果表明单侧刺激可为双耳融合提供参考。
