PROCEEDINGS
 

 Some authors have submitted their papers for a publication in a special issue of Audiology & Neuro-Otology: Audiol&Neurootol 4,1999, "Biomechanics of Hearing".

SCOPE OF THE SYMPOSIUM
 

Recent progress in applied dynamics, modern measurement techniques and microsurgery results in better understanding of the hearing process. Joint efforts allow for the development of advanced diagnosis methods and improved hearing prostheses.
The description of the hearing process with mechanical models offers in particular the simulation of normal and pathological hearing and supports the prediction of surgery effects.
 The Colloquium forms a bridge between acoustical and medical scientists coming from surgery, hearing research and audiology on one hand and mechanical and control engineers on the other. For a successful research there is a need of interdisciplinary cooperation.
 

The topics of the colloquium have been:
 

	Description of the hearing process with appropriate models using Finite Elements, Multibody Systems and Continuous Systems for the outer, middle and inner human ear, respectively.
	Parameter identification of mechanical parts, using physicians' knowledge and clinical observations
	Audiological measurements concerning specific investigations like impedances, pressure and forces as well as transfer functions. Detecting of vibrations and imaging of motion patterns by laser or optoelectronic techniques
	Simulation of the dynamical behaviour of the different parts, including the spatial vibrations and the transfer of sound events to the nerves of the inner ear.
	Simulation of the dynamical behaviour of the entire hearing for normal and pathological situations as well as reconstructed hearing with passive or active implants
