    This paper investigates the variation in floor impact sound within a hybrid-type structure. Floor plans were modified under different conditions, and the study analyzed how floor impact sound varied in plate-type and tower-type layouts with a floor area of 59 m2. The results indicated that the lowest impact sound level occurred when an additional column was placed in the multipurpose room located between the living room and kitchen in the tower-type layout. However, finite element analysis (FEA) alone has limitations in predicting the noise reduction effects of impact noise in actual residential environments. Further analysis is required to assess the insulation performance of impact noise through floor resilient systems or ceiling configurations. Thus, analyzing empirical data from apartment buildings or experimental facilities is essential for a comprehensive evaluation.
