ANALYSIS OF IMPACT SOUND INSULATION PROPERTIES OF RECYCLED RUBBERS FOR TECHNICAL FLOORING IN FITNESS FACILITIES

This work is a comparative analysis of the dynamic stiffness in plates made from recycled rubber intended for their use in technical flooring. The aim is to determine which one of the materials presents the best sound absorbing properties when impact loading conditions for their application in fitness facilities. In addition, the manufacturing of these materials contributes to the optimization of the industrial wastes and reduces the damage to the environment. The recommendations of the standard UNE-EN 29052-1 are considered to determine the dynamic stiffness. The results demonstrate that this product is suitable for its application in technical floors for certain sports activities, because of its low dynamic stiffness, what means that these materials have the capability to isolate the impact sounds quite well. This study is part of a more extensive research project in which some other acoustic parameters are determined, such as the sound transmission loss.
