Abstract
The acoustic method of impedance measurement at the eardrum, described in the preceding paper, has been improved and applied to the investigation of the effect of some pathological changes in the middle ear on the measured impedance. The investigation shows that the otosclerosis and the interruption of the ossicular chain can be easily detected by means of the impedance measurement. An electrical and mathematical model of the dynamics of the middle ear is developed.
