The number of candidates suitable for cochlear implants (CIs) has increased substantially over the last 15 years as a result of a dramatic increase in the effectiveness of and candidacy for these devices. This includes an increasing group of persons, who are cochlear-implanted in one ear but have residual acoustic hearing in the other ear that is typically supported with a hearing aid. These patients are known as bimodal, but we have only a limited understanding of how electric and acoustic hearing interact in everyday complex listening contexts. This may explain the observation that bimodal listeners have difficulty in understanding speech, especially in social situations. This project will develop a virtual bimodal CI listener, i.e. a computer model that is based on the unique physiological characteristics of these listeners for simulating speech intelligibility. The work will explore: (1) the mechanisms of the interaction between acoustic and electric hearing, (2) the usable and used binaural speech cues, and (3) the interdependencies between bimodal hearing and the most up-to-date signal processing strategies in use. This computer model will facilitate an extensive evaluation of signal processing strategies quickly and at low cost. This will result in better hearing for bimodal listeners.

过去 15 年里，由于这些设备的有效性和候选者的急剧增加，适合人工耳蜗植入 (CI) 的候选者数量大幅增加。这包括越来越多的人，他们的一只耳朵植入了人工耳蜗，但另一只耳朵有残余听觉，通常需要助听器支持。这些患者被称为双模式患者，但我们对电听力和声听力在日常复杂听力环境中如何相互作用的了解有限。这可以解释双峰听众难以理解言语的观察结果，尤其是在社交场合。该项目将开发一个虚拟双模态 CI 听众，即基于这些听众独特的生理特征来模拟语音清晰度的计算机模型。这项工作将探讨：（1）声学和电学听力之间相互作用的机制，（2）可用和已使用的双耳语音提示，以及（3）双模态听力与最新使用的信号处理策略之间的相互依赖性。该计算机模型将有助于快速、低成本地对信号处理策略进行广泛的评估。这将为双模听众带来更好的听力。
