An Analysis on the Occurrence of Noise between Floors in Apartment Housing

Abstract

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.
