Abstract
The sound simulation program estimates the sound radiation. It has been developed in our laboratory. A past research estimates the ball impact sound of the golf club. As for past research results, the difference was seen in "Sound collected by the excitation experiment" and "Sound that had been calculated by the sound simulation program" in the driver of the golf club.Therefore, the accuracy of the program is confirmed and improved in the present study. Then, it is preferable to be able to understand the accuracy of the program precisely. The experiment and the calculation are compared by using the plate and the cylinder with few error margins of the finite element model, and then, this research compares, and examines the surface vibration velocity and the sound pressure. As a result, if the error margin of the finite element model is few, it has been understood that the straight advancement sound from the surface vibration velocity and the surface vibration velocity is correctly computable. And, the influence of the diffracted sound was able to be experimented.
