Abstract
In Japan, JIS A 1418-2:2019 specifies the car-tire with impact force characteristics (1) and the rubber ball with impact force characteristics (2) as standard heavy impact sources. In addition, JIS A 1440-2:2007 specifies the measurement method of the reduction of transmitted impact sound by floor coverings on a solid standard floor. It has also been reported that the reduction of transmitted impact sound differs depending on the impact sources of the car-tire and the rubber ball. It has been reported that one of the reasons for different reduction of transmitted impact sound is excessive car-tire impact force, and a tendency for a nonlinear response to impact force for a dry-type floating floor. In this study, an experimental examination is conducted to interconvert the reduction of transmitted impact sound of the car-tire and the rubber ball. This paper discusses the reduction of transmitted impact sound due to the change in impact force by varying the drop height of the car-tire and the rubber ball. The results suggest that the difference in reduction of transmitted impact sound between the car-tire and the rubber ball cannot be explained only by nonlinearity due to the impact force for a dry-type floating floor.
