Focus of research

Research in the department of Clinical and Experimental Audiology is experimental research of the human auditory system targeted to clinical applications in diagnosis, therapy, or rehabilitation of the (impaired) auditory system.

  • Otology. Otological projects focus on different aspects of middle ear surgery and implantable hearing hearing devices: bone-anchored hearing aids (BAHA) and cochlear implants (CI).
  • 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 ototoxic agents or noise. 
  • Auditory profile. 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. 
  • Rehabilitation. In the field of auditory rehabilitation the main emphasis is on fitting techniques. In addition, there are several projects that evaluate the effects of advanced signal processing in hearing aids, e.g. noise reduction and directionality. Usually, we apply a mixture of laboratory tests and field trials.
  • Hearing at work. For hearing-impaired people that experience problems at work we 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).

Curriculum Vitae

Prof. Dreschler , head of the dept. of Clinical & Experimental Audiology of the Academic Medical Centre in Amsterdam, earned his PhD thesis in 1983 at the Free University of Amsterdam. The focus of his research is in psychoacoustical tests of the pathological ear and in auditory rehabilitation with heariung instruments and cochlear implants. Special emphasis is given to problems in the working environment, including the prevention of noise-induced hearing loss.

Employment

1977-1980 Scientist at the dept. of Experimental Audiology of the Free University in Amster¬dam (Head: Prof.Dr. R. Plomp) to conduct the thesis work. The title of the Ph.D thesis was "Relations between psychophysical data and speech perception for hearing impaired subjects".

1980-1987 Head of the Dept of Clinical Audiology in the Academic Medical Centre, which is part of the ENT-department. In this department the main concerns are patient-care, tea¬ching and scientific research on clinical audiology.

1990-2003 Head of the Dept. of Functional Assessment ENT, which consists of the depart-ments of Audiology, Speech and Language Pathology, Vestibulolo¬gy, and Facialis Patholo¬gy.

2001-2003 Interim head of the Department of ENT.

1994- Professor in the Clinical and Experimental Audiology, University of Amsterdam
