Abstract
This paper deals with evaluation of sound quality for aerodynamic sounds generated by a column in uniform air-flow. This study is aimed for improvement of sound quality and performed a sensory evaluation and examined the effect of changing the quantity of physical parameter of aerodynamic sounds on evaluation of tone quality by clarifying a factor concerned with tone quality. As a result of factor analysis, two factors were extracted from the modified aerodynamic sound. In addition, clarified a difference of evaluation about a feeling of change of a sound.
