The majority of domestic researches about floor impact sound is focus on the insulation performance of heavy weight floor. However, the concept of green and sustainable building is spread to all over the world, including Taiwan, and wooden materials are sorted into the type of green materials. Thus, this research took the eco trend to install wooden floor, verifying the relative standards of measurement for wooden floor according to the CNS 15160-11(2009). Moreover, the research probed the improvements of heavy-weight/light-weight impact sound in different wooden surface materials to test the capability of wooden floor. The result shows the Ln,t,w of wooden floor accords the range of the norm, which can assure the suitability of wooden floor. In order to lower the margins between the impact sound pressures, the positions of impact sound source should be placed on six different spots that complied with the standard, and the location of ridgepoles should be taken into account as well. Besides, the performance of impact sound insulation can be enhanced by installing resilient materials on floor surface or mounting damping materials on beams of raised floor.
