Usability of individualized hearing systems - Interaction of algorithms and interactive control

尽管进行了深入的研究和发展，目前的助听器仍然不能完全补偿听力损伤。一个根本的问题是不断发展的助听器信号处理对个体听力障碍和给定声学情况下的听力要求的次优调整。因此，该项目的目的是将有关个人听觉缺陷的知识与确定用户导向听力要求的技术（例如，助听器的手势控制）和新型助听器算法相结合，以优化听力系统的效益和可用性。为此，研究股不同项目提供的所有示范系统将根据一些相关的实际应用场景进行组合和优化。为了定义相关的声学场景，实现这些场景中的相关应用场景，并实现在这些场景中进行的评估实验，开发了动态生成虚拟声学场景的新型交互系统，这是交互听觉系统本身之外的第二个研究重点。由于综合了所有项目的贡献和提供评价方案，项目A构成了整个研究股的中心组成部分。它有助于研究单元解决的所有主要问题，即噪声问题（双耳助听器算法的集成和交互），呈现问题（助听器评估通信条件的音频呈现）和个性化问题（通过手势交互用户控制信号处理）。

Despite intensive research and development, current hearing aids are still unable to completely compensate for a hearing impairment. A fundamental problem is the suboptimal adjustment of the constantly advancing hearing aid signal processing to the individual hearing impairment and the listening requirements in a given acoustic situation. The aim of this project is therefore to integrate the knowledge about the individual auditory deficit with techniques for the determination of useroriented hearing requirements (e.g., gestural control of hearing aids) and with novel hearing aid algorithms, in order to optimize the benefit and the usability of hearing systems. For this, all demonstrator systems provided by the different projects of the Research Unit will be combined and optimized with respect to a number of relevant practical application scenarios. For defining the relevant acoustic scenes, realizing the relevant application scenarios in these scenes, and realizing the evaluation experiments conducted in these scenarios, novel interactive systems for dynamically generating virtual acoustic scenes are developed, which constitutes a second research focus besides the interactive hearing systems themselves. Because ofthe integration of contributions from all projects and the provision of evaluation scenarios, project A constitutes a central integrating part of the whole Research Unit. It contributes to all cardinal problems tackled by the Research Unit, i.e., noise problem (integration and interaction of algorithms for the binaural hearing-aid), presentation problem (audio rendering of communication conditions for hearing-aid evaluation) and individualization problem (interactive user control of signal processing by gestures).
