PPROBLEM TO BE SOLVED: To provide a method for quantitatively evaluating the high and low pitch of a hit sound at hitting a golf ball with a golf club head and its program. PSOLUTION: A first hit sound in the case of a hit of a golf ball with each of a plurality of first golf club heads different from one another is output. Information resulting from comparisons of the pitches of the first hit sounds is acquired. Examinees are separated into at least two groups. Each of second hit sounds that is previously stored in a memory means and an object for evaluation of the pitch of the hit sound is output. The examinee separated from the group listens to the second hit sound output to feel the pitch of the sound. Information of a mental quantity about it is acquired as an evaluated result showing the pitch of the second hit sound. Each of the first sounds differs from one another in at least the maximum peak frequency. In the comparisons of the pitches of the first sounds, the examinee evaluating the first sound with the higher maximum peak frequency as a hit sound with a higher pitch is separated as one with a specified type.
