Abstract

The hitting sound of golf clubs with metal heads and of a club with a wood head were measured to investigate differences in their acoustic properties. Hitting was executed either by a swing machine or a human player. The results of analysis showed that the clubs with metal heads generated sounds around 100dB (LpA, F<sub>max</sub>). This level was 5-15dB higher than that of the club with a wood head. The sounds of the metal-head clubs had relatively larger power in the high-frequency region of 4kHz and above compared to the wood-head club, which increased the overall levels. It would be desirable to develop a metal head with pleasant sound qualities, keeping the sound level lower in order to minimize damage to hearing.
