MIMO acoustic earpiece for combined equalization, feedback cancellation and noise reduction (C01)

点击翻译按钮获取中文摘要

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.
