鉴于只有少数研究关注客观和主观结局的双峰受益，并强调个体数据的重要性，本研究旨在测量人工耳蜗植入成人的客观和主观结局的双峰受益。14名听众与双峰设备的本地化和识别能力进行了测试，使用环境声音，1-talker，和2-talker语音材料。通过一个8扬声器阵列的定位能力进行了测试。对于识别措施，听众被要求重复句子或说出听众听到的环境声音。作为一个主观的问卷，三个领域的韩语版的语音，空间，听觉质量量表（K-SSQ）被用来探讨客观和主观结果之间的任何关系。根据组平均数据，双峰听力增强定位和识别，无论测试材料。然而，对于定位和识别能力，受试者间和受试者内的变异性似乎在测试材料中很大。相关分析显示，客观结果和主观自我报告的双峰设备之间的关系并不总是一致的。总的来说，这项研究支持显着的双峰优势的本地化和识别措施，但大的个体差异双峰的好处，应仔细考虑的临床评估以及咨询。客观和主观的结果之间的差异关系表明，双峰的好处，在传统的本地化或识别措施可能不一定对应于自我报告的主观优势，在日常的听力环境。
Given that only a few studies have focused on the bimodal benefits on objective and subjective outcomes and emphasized the importance of individual data, the present study aimed to measure the bimodal benefits on the objective and subjective outcomes for adults with cochlear implant. Fourteen listeners with bimodal devices were tested on the localization and recognition abilities using environmental sounds, 1-talker, and 2-talker speech materials. The localization ability was measured through an 8-loudspeaker array. For the recognition measures, listeners were asked to repeat the sentences or say the environmental sounds the listeners heard. As a subjective questionnaire, three domains of Korean-version of Speech, Spatial, Qualities of Hearing scale (K-SSQ) were used to explore any relationships between objective and subjective outcomes. Based on the group-mean data, the bimodal hearing enhanced both localization and recognition regardless of test material. However, the inter- and intra-subject variability appeared to be large across test materials for both localization and recognition abilities. Correlation analyses revealed that the relationships were not always consistent between the objective outcomes and the subjective self-reports with bimodal devices. Overall, this study supports significant bimodal advantages on localization and recognition measures, yet the large individual variability in bimodal benefits should be considered carefully for the clinical assessment as well as counseling. The discrepant relations between objective and subjective results suggest that the bimodal benefits in traditional localization or recognition measures might not necessarily correspond to the self-reported subjective advantages in everyday listening environments.
