Modelling the “cocktail-party effect” for cochlear implant and hearing aid users.

Cochlear implants stimulate the auditory nerve electrically and provide profound hearing-impaired or even completely deaf listeners with good abilities to understand speech. Listeners with two implants (bilateral patients) or with a contralateral hearing aid (bimodal patients) can also benefit from basic aspects of spatial hearing, such as left-right discrimination of an acoustic source. However, their speech intelligibility is still much poorer than that of normal-hearing listeners, especially in social situations, such as in restaurants and bars, where normal-hearing listeners show excellent abilities to separate speech from background noise (the “cocktail-party effect”). This project aims to (1) better understand why bimodal and bilateral patients perform poorer in a cocktail-party-like scenario, and (2) evaluate novel sound coding strategies with both synchronized and non-synchronized hearing devices to improve their performance in these challenging acoustic situations. A novel computer model-approach will be used by the candidate to predict speech intelligibility of bimodal and bilateral cochlear implant users in different spatial scenarios with and without additional algorithms. Detailed models of the auditory nerve response to acoustic and electric stimulation will be used, as well as simpler models for speech intelligibility predictions. Comparisons to clinical data will evaluate the approach. A close collaboration with excellent algorithm developers for speech enhancement within the project and collaborations with the recently established university clinics for otorhinolaryngology in Oldenburg and with the biggest implantation center of Europe in Hannover (MHH) ensure high standards in procedures as well as a unique work environment.

The “Models for hearing devices” group (head: Prof. Dr. Tim Jürgens) is part of the Medical Physics Section (heads: Prof. Dr. Dr. B. Kollmeier, Prof. Dr. V. Hohmann) and offers an international scientific environment as well as access to world-class research facilities.
