Abstract
Normal ears and ears affected by various pathologies were studied with a clinical middle-ear analyzer according to the multifrequency tympan ometric concept, by which the resonance frequency of the tympanic memb rane/middle-ear system can be determined. This frequency varies consid erably in normal ears with a mean value close to 1 kHz. Ears with path ologies in the tympanic membrane and otosclerotic ears have resonance frequencies differing significantly from those of normal ears. The eff ects may be explained by considering mass and stiffness components.
