Abstract
Recently, it is necessary to give the additional value to a basic performance of the equipment to be lost of a remarkable difference. Then, it focus on the shutter sound of the camera in this research. It aims to give the quality of sound as an additional value by making comfortable shutter sound. In aiming at making comfortable shutter sound, sound quality evaluation is used. However, when the sound quality evaluation is repeated whenever the sound is changed by a simulation and a structural modification. Then, the regression in a sound quality evaluation result and psychoacoustic parameters is made by using regression analysis. Whether it is possible to provide the directionality of sound quality is verified without sound quality evaluation.
