Patent ID: 7870790

Claim:
A method for evaluating feeling of hitting of a golf club having a three-axis accelerometer disposed on an outer side of a shaft of the golf club, comprising: measuring, by the three-axis accelerometer disposed on the outer side of the shaft, vibration of the golf club appearing in a circumferential direction of the shaft when a golf ball is hit by the golf club; analyzing, by a hand-arm vibration measurement filter, the vibration measured by the three-axis accelerometer; and evaluating the feeling of hitting of the golf club in accordance with an analysis result of the hand-arm vibration measurement filter, wherein a distance between a rear end of the shaft and the three-axis accelerometer ranges from 250 to 300 mm, and wherein when the feeling of hitting of the golf club is evaluated in accordance with the analysis result of the hand-arm vibration measurement filter, the feeling of hitting of the golf club is evaluated in accordance with a time difference between a time when the vibration of the golf club in the specific frequency has attained a peak value and a time when a specific value falls within a range from 40 to 80% of the peak value.
