Not just the interference of horizontal neighborhood noise, the concerned about vertical floor impact sound has become upward. The dispute cause by residential floor impact sound often happen. Domestic standard floor impact sound measurement labs are few. In order to improve the interference of impact sound to residential floor, in this study we build a imitate-standard double reverberation chambers without the flanking sound effects. Take the spatial correction and comparison of sound field property with a series of experimental groups test. We make sure the floor impact sound experimental can be used. Since existing floor is not easy to change, we often cover resilient materials over the floor to improve the impact noise. We provided a complete floor impact sound insulation indexes of raised floor and resilient materials through a series of experiments.
