Anti-vibration hangers can effectively reduce sound and vibration transmitted through structural connections between concrete slabs and supported ceilings. This research examined the impact of installing anti-vibration hangers on reducing floor impact sound through mock-up tests. Results showed that with anti-vibration hangers, vibration acceleration levels decreased above 200 Hz for both heavyand light-weight impact sources. In terms of floor impact sound, reduction in heavy-weight impact sound was marginal, occurring only below 200 Hz with a maximum decrease of 1.7 dB. In contrast, the sound pressure level for light-weight impact sound steadily decreased by at least 2.7 dB starting from 630 Hz, reaching a maximum reduction of 4.8 dB at 1250 Hz. Therefore, the effectiveness of reducing both vibration acceleration and floor impact sound was confirmed for a lightweight impact source. This suggests that the application of anti-vibration hangers can effectively reduce floor impact sound, particularly in response to continuous impulsive sound like those generated by tapping machines.
