Analysis of floor impact noise reduction and impact force by floor mats

This study is a basic research on improving floor finishing materials technology to reduce floor impact noise in apartments. The floor impact noise reduction performance and impact force of floor mats were measured on a general standard floor structure in Korea (concrete slab 210 mm + EPS 30 mm + finishing mortar 50 mm). Six types of PE mats, three types of EVA mats, and three types of PU mats were targeted. Lightweight and heavyweight impact noise were measured and evaluated according to KS F ISO 16283-2 and KS F ISO 717-2, and the floor impact noise reduction value of the mat was evaluated by the difference in the level of impact noise according to the installation of the mat. In addition, the impact force of the mats was measured according to JIS A 6519. The reduction performance of lightweight impact noise was high in the order of PU, PE, and EVA. PE mats showed a reduction performance of up to 4 dB in heavyweight impact noise. In addition, the impact force of the PE mats was the smallest, and the impact force decreased as the thickness of the mat increased.
