Development of auditory training application for volleyball players

Abstract

In various ball games, players make appropriate plays by obtaining information from their surroundings. In volleyball, players also obtain auditory information from the sound of balls being hit, people's voices, footsteps, etc. However, details such as how to use it have not been clarified. The purpose of this research is to develop a method for improving volleyball competitiveness using auditory information. The authors investigated the acoustic characteristics of good and bad sounds that athletes usually express intuitively in words, and also investigated the relationship between acoustic characteristics and athletes' subjective evaluations of the quality of the meat. We investigated the relationship. As a result, we confirmed that there are differences in the sounds that are perceived as "good" or "bad." Furthermore, we conducted acoustic measurements and acoustic analysis of serves and spikes for experienced volleyball players, and based on the analysis results, we developed an auditory training system to enable accurate discrimination of sounds during competition. In the future, we will collect logs from experiment participants who trained using the application and analyze differences in training effects due to differences in years of experience. We will also consider how to create a more efficient training system.
