Research foci (and basic equipment-based research projects):
Evaluation of the mechanics of the middle ear:
Modelling of the mechanics of the ossicular chain with the goal to calculate the matrix of the system. Electrostatic forces were used to excite the ossicles. To begin with the stiffnes and damping constant of the angular ligament was measured.

Results:
Schön F, Müller J, Measurements of the ossicular vibrations in the middle ear, AudiolNeurotol 1999;4: 142-149
Waller T, Schön F, Dynamic measurement of stiffness parameters of the circular ligaments of the stapes using electrostatic forces, Laryng-Rhino-Otol. Suppl. 2002 in press. Stiffnes constant for the angular ligament = 940 +/- 350 N/m, cirtical damping ratio = 0.38 +/- 0.09

Equipment:
Laser - Doppler Vibrometer, FFT - Analysator, controller for the electrostatic excitation
