The Characteristics of Heavy-weight Impact Sound and Vibration According to the Change of Impact Force in An Apartment Building

충격력 변화에 따른 공동주택의 중량 충격음 및 진동 특성

To reduce the structure-born sound by floor impact source in an apartment building, it is necessary to identify the relationship between floor impact sound and vibration. Various impact sources which were made by a bang machine and an impact ball were used for measurement of impact sound and vibration. The experimental results show that the linear relationship between floor impact sound and vibration was in existence despite of various floor impact sources.
