Abstract
This paper describes guideline of accuracy improvement in inverse-acoustic analysis (IAA). IAA is a technique for identifying the vibration with a high contribution of the sound radiation. However, the identification result has the possibility that the result of good accuracy is not obtained. One reason is the shape of measurement points of the acoustic pressure decreases the result of accuracy. Therefore, this study focused on the shape of measurement points of the acoustic pressure. To reveal influences of shape of measurement points in identification, sound source is identified from the measured sound pressure with different shape of measurement points.
