The long-term goal of this project is to achieve acoustically transparent speech communication and hear-ing support by means of a multi-input multi-output (MIMO) earpiece with integrated microphones and re-ceivers. The main research question is how to optimally exploit the availability of multiple microphones and receivers in the ear canal and vent to develop combined solutions for sound pressure equalization at the ear drum, for acoustic feedback cancellation, for (active) noise reduction and for occlusion control. To this end, novel sig-nal processing algorithms as well as electro-acoustic models will be developed that enable to individualize these solutions for each user and take into account the interaction effects between the dif-ferent objectives.

该项目的长期目标是通过集成麦克风和接收器的多输入多输出（MIMO）耳机实现声学透明的语音通信和听觉支持。主要的研究问题是如何最佳地利用耳道和通风口中的多个麦克风和接收器的可用性，以开发用于鼓膜处的声压均衡、用于声反馈消除、用于（主动）降噪和用于闭塞控制的组合解决方案。为此，将开发新的信号处理算法以及电声模型，使这些解决方案为每个用户个性化，并考虑到不同目标之间的相互作用。
