Among the various evaluation quantities of floor impact sound isolation performance measured in RC apartment houses in accordance with JIS, we investigated the correspondence between the L number, A-weighted floor impact sound level, and inverse A-weighted floor impact sound level. As a result of the study, it was found that the A-weighted floor impact sound level and the inverse A-weighted floor impact sound level can be matched to the L number within a certain range by setting the optimal correction value for each floor structure.
