| Research Abstract |
In spite of my examination from various hearing tests, I couldn't clarify a relationship between auditory fatigues and noise that are considered to be part of the reason for hearing loss in Kendo. Yet, it is reaffirmed, out of the study of the safety of Kendo equipment and gear, that the structure of traditional men increases buffering effect to striking power. Also, I examined acoustic environment (reverberation time). Since reverberation time is shorter in traditional dojo than in gymnasium, there is a need for detailed study on building construction such as ceilings, walls, and windows.
