speaker performance on sports performance -Behavior analysis using OpenPose

Most of the sound quality evaluation methods for loudspeaker are based on physical evaluation and subjective evaluation. In the physical evaluation, we focus on the peak sound pressure and the rise speed. In the subjective evaluation, the sound quality is evaluated by the subjective evaluation experiment using the sound quality evaluation word. However, it's difficult for people who don't have professional knowledge in the field of acoustics to judge the performance of a loudspeaker from these evaluation methods. In addition, according to the engineers of a speaker manufacturer, the difference of the sound quality of the loudspeaker may affect the movement and motivation of the game. In this study, aims to evaluate the sound quality of loudspeaker objectively from a new point of view. In order to clarify whether the difference of the sound quality of the loudspeaker affects the movement, the movement analysis using OpenPose was carried out. As a result, it was found that the complicated motion was not likely to be affected by the difference of the sound quality of the loudspeaker. However, the results suggested that simple and familiar actions may be affected by the difference in loudspeaker sound quality.
