A1 A Study of Comfortable Hitting Sound of Golf Club

Abstract

In the evaluation of hitting sound of a golf club driver, not only the radiated sound from the club head but also sound from the ball and the club shaft must be considered. In this study, the sound was divided into three time domains, before, while and after the impact. Three sounds were generated by wind roar generated by the club shaft, vibration of the ball and vibration of the club head. In the sensory evaluation, the sound was artificially composed by fundamental vibrations of the club face and the ball derived in the simulation and the method of paired comparisons was employed. When the ratio between ball and club face frequencies was 2:3, the sound obtained good sensory evaluation of 'powerful' and 'long distance'. This frequency ratio of 2:3 is perfect consonant.
