Since the 1990s, collective residential buildings in Korea have been constructed taller than before, and air-entrained concrete has been used as flooring material. Noise between the floors of collective residential buildings has gradually become a social issue. People today generally expect higher residential living standards than has existed in the past, but standards have not reached the level expected by the culture. Disputes over noise between floors also occur because of the culture mainly living on the ground floor of a multi-story home in Korea. In the other words, noise disputes between floors occur because of both the structure of the floors and people's living patterns. Noise complaints are classified as those reported at the time of the incident, whether the incident occurred during the day or at night. Also it is very difficult to prove, from the nature of the noise between the floors. This article examines the legal standards for noise regulation between floors in countries like Japan, Germany, and the United States (especially New York). It then compares the present Korean regulations with other countries' regulations on noise between floors. Through this comparison, we ask to Korean government continuous reorganizing about regulations on noise between floors. Also it was studied a concrete application of solutions to resolve disputes through a suit or reconciliation. Studying these cases, we divided three types: solving by an autonomous covenant; a reconciliation through "Neighborhood Center", "Happy Support Center Together With Our House" or "Environmental Dispute Adjustment Committee"; and a suit. Merely stating that noise between floors is considered one form of dispute resolution causes conflict among neighbors, so that residents have to make an effort to reduce noise.
