Abstract

In contrast to most of the clinical examinations the sonotubometric assessment of the eustachian tube function allows the registration of the tube opening at the perforated as well as the intact eardrum at physiological conditions. In this paper a new procedure is introduced which performs a measurement of the transmission path nose/ear with so-called perfect sequences. With digital signal processing techniques the generation of a new curve for medical diagnostics and the calculation of a broadband frequency spectrum is possible. The gain of information is used to improve the quality and reliability of the dynamic exposition of the tube function. A continuative objective of this method is the extraction of novel features relevant for medical diagnostics.
