To evaluate the excitement caused by baseball plays, we examined the relationships among the audience's cheering volume, changes in win probability, and events such as achieving a hit during a professional baseball game. The total number of events and mean cheering volume throughout the game were 70 and 86.99 (± 6.35) dB, respectively. There was a significant correlation between the cheering volume and win probability. On comparing the former among events, the volume was significantly higher when achieving hits compared with outs or walk/hits by pitch. It was also significantly higher when there were runners in a scoring position than when there were no such runners. Based on the results, the audience may become more excited when win probability markedly changes, there is a hit, or there are runners in a scoring position.
