The eustachian tube is an organ to tie middle ear and pharynx to. The symptom due to the eustachian tube is stenosis and patulous eustachian tube. The technique that is used for treatment and the diagnosis of the stenosis is the quantification of the eustachian catheterization. The doctor sends air in an eustachian tube and diagnoses a situation from the sound. I gather an insufflation sound of the patient so far and investigate the features of the sound. I try the self organizing map. But, the decision of the analysis section of the insufflation sound does manually. Therefore, to realize automation I examined time lag before a insufflation sound being detected and the outbreak frequency.
