In the research group Clinical and Experimental Audiology the focus is on the following themes:
Prevention of hearing loss
We conduct several studies on the damaging effects of ototoxicity and noise. Special focus is on the role of oto-acoustic emissions as an early indicator for the sensitivity of the ear for hearing loss due to noise or due to ototoxic agents and irradiation.
The projects within this theme cover a number of psychophysical tests that have been developed to understand the supra-threshold behaviour of the ear for different auditory tasks in communication: e.g. speech perception, discrimination, spatial hearing. The projects are related to loudness perception, auditory filtering, and (the modelling of) speech perception.
In the field of auditory rehabilitation the main emphasis is on fitting techniques. Also, we developed the BRIDGE system, that is used for hearing aid selection in the netherlands. In addition, there are several projects that evaluate the effects of advanced signal processing in hearing aids, e.g. noise reduction and directionality. For hearing-impaired people that experience problems at work we will develop new tests and methods to make a detailed and well-structured analysis of the problems, related to the match of (reduced) auditory capacities and auditory demands (at work).
