Abstract—About 60 percent of Koreans are living in a public house like multi-unit dwelling. Interlayer noise in living apartment houses rises a social problem in a densely populated country. Many countries established a law to reduce noise pollution induced by floor impact sound. This paper presents the test results of eight resilient materials in floating floor system subjected to long-term load. The main parameters of test specimens were types of materials, density of material, magnitude of load, and duration of load. Test results indicated that the duration of load strongly steadily increased deflection. In addition, long-term deflection of resilient materials was affected by types of materials, density and bottom plate shapes.
