DESCRIPTION (provided by applicant): The current fitting approach adopted for cochlear implant (CI) users falls along the lines of "one-size-fits-all", in that it is assumed that the initial fitting in the clinic should work equally well in all listening environments. Speech coding algorithms and associated parameters (e.g., compression function) are fixed and are not optimized in any way by either the patient or clinician for different listening situations (e.g., quiet, music, noise). The present study addresses this major limitation with the use of a portable research speech processor that allows users to: (a) change MAP parameters based on two different outcome measures (subjective quality ratings and consonant intelligibility) (b) customize the MAP to different listening situations for maximum benefit, and (c) collect feedback and allow the recording of real acoustic signals for further analysis. In this study, unilateral, bilateral and bimodal users will participate in double-blind field trials to assess the true benefit of a speech processor that can be easily customized by the users to fit their needs based on subjective quality ratings or speech intelligibility measures. The overarching hypothesis of this project is that maximum benefit, both in terms of subjective quality and intelligibility, can be obtained when the cochlear implant devices are customized (by the users) to the various listening situations. The outcomes of the field studies will tell us about the difficulties experienced by CI users in real-world situations as well as the value and additional benefit of customizing speech coding algorithms to different environments, all based on feedback from CI users. Such feedback and user interaction can not be gathered using existing commercial processors, yet it is critically needed to move the field forward. PUBLIC HEALTH RELEVANCE: The outcomes of this work can greatly benefit the overall quality of life for a large number of cochlear implant users. Cochlear implant users who are able to communicate effectively in noisy environments have greater opportunity for integration into mainstream education, increase their productivity at home or work and contribute more in the nation's economic growth and competitiveness.

描述(由申请人提供)：目前对人工耳蜗(CI)使用者采用的配戴方法遵循“一刀切”的原则，因为它假设在临床上的初始配戴在所有听力环境中都应该同样有效。语音编码算法和相关联的参数(例如，压缩函数)是固定的，并且患者或临床医生对于不同的收听情况(例如，安静、音乐、噪声)没有以任何方式进行优化。本研究通过使用便携式研究语音处理器解决了这一主要限制，该处理器允许用户：(A)基于两种不同的结果测量(主观质量评级和辅音可理解性)改变MAP参数；(B)针对不同的收听情况定制MAP以获得最大益处；以及(C)收集反馈并允许记录真实声学信号以供进一步分析。在这项研究中，单侧、双边和双模式用户将参加双盲现场试验，以评估语音处理器的真正好处，该处理器可以根据用户的主观质量评级或语音清晰度测量轻松定制以满足他们的需求。该项目的主要假设是，当(用户)根据不同的听力情况定制人工耳蜗植入设备时，可以在主观质量和可理解性方面获得最大好处。实地研究的结果将告诉我们CI用户在现实世界中遇到的困难，以及根据CI用户的反馈定制不同环境的语音编码算法的价值和额外好处。这样的反馈和用户互动不能用现有的商业处理器收集，但它是推动该领域向前发展的关键。 公共卫生相关性：这项工作的结果可以极大地提高大量人工耳蜗使用者的整体生活质量。能够在嘈杂环境中有效沟通的人工耳蜗使用者有更大的机会融入主流教育，提高他们在家庭或工作中的生产力，并为国家的经济增长和竞争力做出更大贡献。
