    This study examined the influence of excitation and receiving positions on heavy-weight floor impact sound evaluation in apartment buildings using a tire impact source. Measurements were taken in 59 identical apartment units having the same floor structure. The results showed that impact positions in the center and near windows contributed 21.3 % ~ 22.7 % to the single-number quantity, while positions near the corridor contributed 16.3 % ~ 17.6 %. Regarding microphones, position near windows contributed 27.0 % ~ 28.5 %, corridor areas contributed 16.2 % ~ 16.9 %, and the center position contributed 11.5 %. These findings differ from those of previous studies using rubber ball impact sources, highlighting the importance of impact source characteristics in sound pressure distribution. The findings of this study suggest that floor structure design needs to be reconsidered due to the change in impact sources. While this study focused on a specific floor plan and structure, further research on different layouts and floor structures is needed for a comprehensive understanding.
