Human speech communication is the foundation of our culture and key to active participation in society. It is challenged by a number of factors, such as complex acoustic backgrounds in social gatherings, com-plex room acoustics, ubiquitous noise and reverberation, as well as hearing impairment. These factors limit the capability of individuals to achieve their communication goals in daily-life environments, which holds in particular for individuals with hearing impairment. Despite the tremendous progress due to digital signal processing being introduced as a standard, current electroacoustic devices that support acoustic commu-nication in these situations provide only a limited benefit. This is mostly because the interrelation between the challenging factors mentioned above with the device function and the performance of the individual listener are not well understood. In particular, mostly passive listening is assumed in the design of current devices, whereas real-life communication involves active listening by, e.g., positioning both ears of the user in an optimum way, utilizing binaural perception advantages, and acting appropriately. Hence, human acoustic communication involves a loop that includes the sound field, the device, the perception of the user and the user’s active behavior. The collaborative research centre (CRC) Hearing Acoustics goes well be-yond earlier research by systematically investigating this acoustic communication loop, and taking it into account for auditory modeling as well as for hearing device development and evaluation. The CRC aims at a fundamentally better quantitative understanding of the principles underlying the processing of complex auditory and audio-visual scenes by humans, the implementation of this knowledge in algorithms for per-ceptual enhancement of acoustic communication, and the evaluation of these algorithms for different appli-cations in consumer electronics, assistive listening devices and hearing devices. In addition, the CRC es-tablishes novel lab-based subject-in-the loop assessment procedures, which use audio-visual virtual reality to embed the listener in a simulated communication loop. This ensures a high level of ecological validity of the experimental results, i.e., laboratory results reflect hearing-related communication performance in real-life conditions to a higher degree than what earlier experimental approaches offered. To achieve these goals, the CRC links the different disciplines that contribute to the research field, i.e., acoustics, psychoa-coustics, audiology, engineering and physical modelling. The research output, i.e., better support by elec-troacoustic devices for enhanced acoustic communication (speech, music) in real life, better principles of man-machine interaction with consumer electronics, and an extensive basis for improved design and as-sessment of hearing devices, is highly relevant to our (ageing) communication society.

人类语言交流是我们文化的基础，也是积极参与社会的关键。它受到许多因素的挑战，例如社交聚会中复杂的声学背景，复杂的房间声学，无处不在的噪音和混响，以及听力障碍。这些因素限制了个体在日常生活环境中实现沟通目标的能力，这对听力障碍的个体来说尤其如此。尽管由于数字信号处理作为一种标准被引入而取得了巨大的进步，但目前在这些情况下支持声学通信的电声设备只提供了有限的好处。这主要是因为上述提到的具有挑战性的因素与设备功能和单个听者的表现之间的相互关系没有得到很好的理解。特别是，在当前设备的设计中，大多假设被动倾听，而现实生活中的交流涉及主动倾听，例如，以最佳方式定位用户的双耳，利用双耳感知优势，并采取适当的行动。因此，人类声学通信涉及一个包括声场、设备、用户感知和用户主动行为的循环。听力声学合作研究中心（CRC）通过系统地研究这种声学通信回路，并将其考虑到听觉建模以及听力设备的开发和评估，远远超出了早期的研究。CRC旨在从根本上更好地定量理解人类处理复杂听觉和视听场景的基本原理，在声学通信感知增强算法中实现这些知识，并评估这些算法在消费电子产品，辅助听力设备和听力设备中的不同应用。此外，CRC建立了新的基于实验室的受试者在环路评估程序，该程序使用视听虚拟现实将听者嵌入模拟通信环路中。这确保了实验结果具有高水平的生态有效性，即，与早期的实验方法相比，实验室结果在更高程度上反映了现实生活条件下与听力相关的沟通表现。为了实现这些目标，中心将有助于研究领域的不同学科联系起来，即声学、心理声学、听力学、工程学和物理建模。研究成果，即电声设备在现实生活中更好地支持增强声学通信（语音，音乐），更好的人机交互原理与消费电子产品，以及改进听力设备的设计和评估的广泛基础，与我们（老龄化）的通信社会高度相关。
