Outline of Final Research Achievements

In this study, we investigated the effects of auditory information on sports performance. First, we developed a headphone with the functions of “reversing the left and right surrounding sound” and “adding delay to sound.” Second, we clarified the influence of impact sounds of the ball and putter head on the feeling of the putt. Expert golfers and novices performed a putting task. The participants were asked to putt a golf ball to a target placed at three different distances. They performed the task in two different modes: presence (S) and absence (NoS) of the impact sound. As a result, for the experts, the absolute error of putts was significantly increased for the long target distance under the NoS condition, when compared with the S condition. For the novices, there were no differences between the two conditions for each of the target distances. These results suggest that impact sounds are useful for expert golfers and strongly influence their feeling of the longer putt.
