More than 15% of our population exhibit a hearing loss that needs treatment and increases in prevalence with age. It is often (partially) compensated more than 10 years too late with a hearing aid - with limited success. Hence, a personal binaural hearing aid should be developed that offers an earty access to communication assistance and is beneficial even for normal to mildly hearingimpaired persons. The long term goal of the current project therefore is the seamless integration of hearing support for normal or mildly hearing-impaired listeners in acoustically challenging situations in an acoustically "transparent", space-aware binaural heanng device which as well incorporates more aggressive signal processing and enhancement techniques for supporting listeners with a substantial hearing impairment. To achieve this goal, the concept of an acoustically transparent hearing device in combination with several binaural enhancement schemes was successfully developed, implemented in a demonstrator and tested. Moreover, machine listening approaches for automatic object recognition and localization in a complex acoustic environment were demonstrated to yield superior performance in an international challenge. Building on these results, the following objectives will be pursued in the upcoming funding period:- Further optimization of the acoustic transparent ear piece which should eventually enable an active noise cancellation, i.e., the possibility of (external) noise suppression even if an acoustic leak exists where noise from the outside can bypass into the ear canal.- To further develop "space aware" hearing aid processing in combination with these advanced presentation techniques. Solutions will be considered that aim at source enhancement and separation utilizing perceptual properties of those individual listeners that profit from binaural enhancement ("enhanced reality"). Specifically, listeners with impaired binaural auditory functions are supposed to profit the most.- To develop a set of scene classification and source localization algorithms for use in binaural hearing aids that provide an improved functionality of binaural noise reduction and source enhancement algorithms. They should eventually be combined, e.g., with gesture control by the listener to select the source that should be enhanced.- Enhancement ofthe perception of certain acoustic sources in a (binaural) spatial environment using source enhancement in combination with localization algorithms.- To integrate these technical developments together with other innovations from the Research Unit into a demonstrator device for a future generation of a fully "space aware" and scalable binaural hearing aid.

超过15%的人口表现出需要治疗的听力损失，并且患病率随着年龄的增长而增加。使用助听器往往(部分)晚了10多年才得到补偿--效果有限。因此，应该开发一种个人双耳助听器，这种助听器可以很好地获得通信帮助，甚至对正常到轻度听力受损的人也是有益的。因此，当前项目的长期目标是在听觉上具有挑战性的情况下为正常或轻度听力受损的听众提供无缝集成的听力支持，这是一种声学“透明”、空间感知的双耳保健器，它还结合了更积极的信号处理和增强技术，以支持听力严重受损的听众。为了实现这一目标，成功地开发了与几种双耳增强方案相结合的听觉透明听力装置的概念，并在演示器中进行了实施和测试。此外，在复杂的声学环境中，用于自动目标识别和定位的机器监听方法被证明在国际挑战中具有优异的性能。在这些结果的基础上，在即将到来的资金期将实现以下目标：-进一步优化声学透明耳机，最终应能实现主动噪音消除，即即使存在声学泄漏，也可能抑制(外部)噪音，因为外部噪音可能绕过耳道进入耳道。-与这些先进的呈现技术相结合，进一步开发“空间感知”助听器处理。将考虑旨在利用受益于双耳增强(“增强现实”)的单个听众的感知特性的源增强和分离的解决方案。具体地说，双耳听觉功能受损的听众应该受益最大。-开发一组场景分类和源定位算法，用于双耳助听器，提供双耳降噪和源增强算法的改进功能。它们最终应该与收听者的手势控制相结合，以选择应该增强的声源。-使用声源增强与定位算法相结合来增强在(双耳)空间环境中对某些声源的感知。-将这些技术发展与研究单位的其他创新集成到演示设备中，以用于未来一代完全“空间感知”和可扩展的双耳助听器。
