Research area B: Towards Better Hearing Devices
Building on the quantitative knowledge of hearing impairment and its consequences for deteriorated signal processing in the auditory system from research area A, a theory-guided approach towards improving the ‘critical issues’ in implantable and conventional hearing devices will be implemented.
By combining the unique mixture of knowledge from auditory physiology, signal processing, psychophysics, and the technological basis for innovative stimulation techniques, the principal investigators cover the whole processing chain from the acoustic signal to perception. They strive to improve hearing devices by implementing appropriate model-based and optimized stimulation and signal processing techniques as well as by optimizing fitting and auditory rehabilitation based on an individualized auditory profile and on expectations by the user of the hearing device. Specific challenges to be tackled within two task groups are innovative signal processing techniques compensating for the ‘information loss’ in impaired hearing and the individualized, personalized adaptation of the parameters of the hearing device. The research in this area will be organized in three main subsections:
Improving stimulation techniques: Considering acoustic, mechanical, neural and optical stimulation of the auditory system and the respective techniques to provide optimum stimulation.
Model–based improvement of aided performance: aided performance for different types of hearing devices will be predicted and optimized in a rational, theory-driven approach.
Improving the individual benefit from hearing devices using optimized indication and hearing device selection techniques, model-based optimized fitting and benefit assessment techniques, as well as innovative user-control to match the device to the individual’s needs.
