The sounds of floor traffic and dropped objects are important when considering types of flooring materials. The cushioning of impacts reduces the generation of airborne sound within the room and the level of sound that can be transmitted to adjacent areas. It also minimises the transmission of impact-generated, structure-borne noises throughout the building. In multifamily dwellings, the transmission of impact-generated noise is of primary concern. Resilient flooring, in general, "give" under the impact of footsteps, dropped objects and rolling loads. The resilience helps to reduce traffic noise. In comparison with other hard-surfaced flooring (wood, marble, ceramic, concrete, metal), resilient floors are low noise producers.
