This paper suggests the motion measurement method of the eardrum that considered as one of the factors which cause Pressure-Comfort, and searches for the validity of the measurement method. And this paper presents the method of the evaluation between eardrum motions and sensitivity parameters in the pressure load by using the discriminant analysis. As the motion measurement method of the eardrum, this paper suggests the illumination difference method. And in a compress and decompress load, the motion of the eardrum is measured by using the illumination difference method, the questionnaire is carried out at the same time. At result, the estimated equation between the volume of each parts of eardrum as explanation variable and the sensitivity parameters as criterion variable is established by using the discriminant analysis. And this paper can present the motion of Umbo controls Pressure-Comfort.
