“…The floor impact sound generated in apartments considerably affects the comfort of residents, as indicated by research across Korea, Japan, and Europe, among other countries [1][2][3] Particularly, most Korean people live in apartments built with concrete and their in-door lifestyle is that they live in bare feet. This lifestyle and structure showed that with the amplification of impact sounds, which had low frequencies, and the reduction of impact sound, it was made more difficult because of the propagation characteristics of low frequency [4][5][6][7][8][9].…”

The exposure of a structure to an acoustic domain induces a sound field owing to the interaction of the air-fluid and structure at the acoustic–structure boundaries. It is difficult to predict sound pressure level through vibration mode, due to the acoustic mode of the coupling effect between vibration and sound in addition to the acoustic mode induced by vibration mode generated by external force. In this study, the acoustic mode induced by structural vibration modes were predicted through a numerical analysis. A finite element model of a reverberation chamber with a shell at one side was constructed, and modal parameters of the vibration and acoustic modes were evaluated through an eigenvalue analysis. In addition, the sound pressure generated by impact loading of the shell were predicted by vibration mode through a time-domain structure–acoustic coupling analysis. The vibration and acoustic modal responses were identified from the measured responses, and the acoustic mode associated with a specific vibration mode was examined. The results showed that the acoustic mode from the coupling effect was verified, and sound pressure prediction from vibration mode was possible if considered as the coupling effect. The proposed approach can be applied to predict the heavy-weight floor impact sound from the vibration of slabs in apartments.

“…Due to the economic development, urbanization and increase of nuclear family has been rapidly progressed and apartment building has grown to more than 60 percent of the entire household diffusion rate since the late 1980s [1]. In addition, residents' demand has increased for more pleasant, serene sound environments in these high-density communities.…”

The purpose of this study is to determine the actual state of noise occurrence in apartment-unit households by utilizing state data to examine individual noise sources and the types of noise between floors. Among the types of noise between Floors, the top four noise sources were conversation and electrical appliance noise in the airborne noise category, and foot-stepping noise and object-dropping noise in the direct impact noise category. The result shows that in three sources (other than foot-stepping noise), the equivalent sound level was found to exceed the standard value in a specific time slot. The frequency of noise occurrence was shown to be highest between 18:00 and 21:00, after household members had come home from work. Therefore, to reduce noise between floors, a management plan should be introduced based on the actual state of the noise occurrence, considering the individual noise source and the time slot during which noise frequently occurs.
