Outline of Final Research Achievements

Commercial equipment is available for conducting Eustachian tube function tests but, generally, the Eustachian tube insufflation method doubles as a treatment and diagnosis. However, with the Eustachian tube insufflation method, the doctor merely performs the auscultation. That is, the technique is not objective. To overcome these disadvantages, we set out to develop a system that would enable the objective evaluation We sampled a wide range of Eustachian tube insufflation sounds and tried to identify the acoustic features of specific pathological conditions. However, it was so difficult to find the features and to classify according to observation of spectra completely. Therefore, we proposed a method of inputting the frequency analysis results as feature vectors to a Self-Organizing Map.
