Outline of Final Research Achievements

In this study, I tried the upper respiratory tract form evaluation that could use in combination four items of 3 4 upper respiratory tract form fluid analysis solid model making every breathing style by the three dimensions CT at the time of 2 acoustic feature awakening of 1 snoring worldwide about a patient with snoring, the sleep breathing disorder. As a result, I made the three-dimensional upper respiratory tract model for the cause by CT data and confirmed that the outbreak of the simulation snoring sound was possible when I added the vibration of a mucous membrane made from current of air speed and pressure information provided by fluid analysis to the soft palate which was one of the responsibility parts of snoring.
