Understanding the Impression Structure for Badminton Impact Sound, and its Relationship with Acoustical Characteristics

Abstract

In many ball games, research on the sound quality of the sound generated when hitting a ball is underway. This is because the comfort of the impact sound exists as an important factor for athletes. In this study, we investigated the elements necessary for the comfortable impact sound, targeting the impact sound of badminton. In the experiment, the impression of the impact sound reproduced from the headphones was evaluated by the SD method. As a result, it was found that the impression of impact sound can be expressed by Beautiful & Metallic, Powerful and Spatial Factor. In addition, it was suggested that the Beautiful & Metallic Factor might be associated with the elastic performance in badminton competition, and the Powerful Factor might be associated with the flying performance. Furthermore, we examined acoustical characteristics that correlate well with each factor, and constructed the sound quality estimating model for the impact sounds.
