The project was divided into six scientific work packages
Work package 1 was mainly handled by DTU, and the main result of the work was a Matlab-based tool to simulate speech in acoustic rooms with different reverberation and background noise. This is an important tool for hearing aid evaluation and controlled research setups.
Work package 2 was mainly handled by Ecole Normale Superior, and the main result of the work was a reduction of the decoding error from 20 percent to 3 percent for 5 seconds speech segments.
Work package 3 was mainly handled by University College London and work package 4 was mainly handled by DTU. Work package 3 focused on brain responses from normal hearing subjects, and main results were obtained in understanding involuntary shifts of attention (distraction), the effect of cognitive load on auditory processing, and gaze location.
Work package 4 focused on brain responses from hearing-impaired subjects, and interestingly it was demonstrated, that the steering worked for both normal-hearing and hearing-impaired listeners in a closed-loop system.
Work package 5 was mainly handled by University Hospital Zürick, and main results were a multi-microphone platform combined with general acoustic scene analysis, which allows for localization and streaming of different speakers.
Work package 6 was mainly handled by Eriksholm Research Centre and consisted of integrating findings from all other work packages into a real-time prototype hearing aid consisting of behind-the-ear shells with microphone, dry electrodes (without amplifiers) and processing unit. Additionally, this work package also developed the eye gaze steering algorithm needed for Demonstrator2.
