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

尽管进行了密集的研究和开发，但目前的助听器仍然不能完全弥补听力障碍。一个基本的问题是，在给定的声学条件下，不断进步的助听器信号处理对个体听力损伤和听力要求的次优调整。因此，本项目的目的是将有关个体听力缺陷的知识与确定面向用户的听力需求的技术(例如，助听器的手势控制)和新的助听器算法相结合，以优化听力系统的益处和可用性。为此，研究股不同项目提供的所有演示系统将结合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，开发了一种新型的动态生成虚拟声学场景的交互系统，这是除了交互听力系统本身之外的第二个研究重点。由于整合了所有项目的贡献并提供了评价方案，项目A构成了整个研究股的核心组成部分。它有助于研究股处理的所有基本问题，即噪声问题(双耳助听器算法的整合和相互作用)、呈现问题(用于助听器评估的通信条件的音频再现)和个性化问题(用户通过手势对信号处理进行交互控制)。

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).
