Section C - Applications
The long-term goal of this project is to achieve acoustically transparent speech communication and hearing support by means of a multi-input multi-output (MIMO) earpiece with integrated microphones and receivers. 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.
Audio content is commonly reproduced over loudspeakers in reverberant and noisy environments. This often leads to non-optimal reproduction conditions. Impairments can both be with respect to the spatial and timbre fidelity of the reproduction as well as with respect to speech intelligibility. This project will focus on robust methods for compensating for the non-optimal acoustical conditions and hearing capabilities of the listeners that can be applied in multiple scenarios.
This project aims at providing the scientific basis for the assessment of individual disability due to hearing impairment and relief obtained from hearing devices with optimum ecological validity and sufficient effect size. The measures to be developed will cover communication abilities, social interactions, and participation.
Acoustic scenes created in virtual reality with life-like realism and features can be used to address important questions on auditory perception beyond the scope of the simplified stimuli and conditions of classical psychoacoustic laboratory tests.
