In the conventional design process of the golf club, maximizing the ball carry distance was 1st design objective. However, it is difficult to increase the distance more than other golf club maker, because volume of the club head, groove depth of the head face and etc.. are regularized by Golf Official Regulation. In this paper, to characterize the golf club and get ahead of the other maker, structural design of golf club based on the sound quality is discussed. Evaluating the sound quality of golf sound, most sensitive frequency range to improve the impression of sound is specified. And structural modification is applied to decrease the sound pressure of sensitive frequency range.
