In the case that such a floor noise problem occurs at a serious level, it is only a way to solve the dispute through the civil litigation between the parties for the actual damage relief, and it is necessary for the claimant to prove the extent of the damages, It is a fact that the lawsuit itself is not easy because the cost of the appraisal exceeds the compensation amount. In this process, many problems become the goal of emotions, leading to serious crimes among neighbors, which is becoming a big social problem.

Meanwhile, government agencies such as the Ministry of Land, Transport and Maritime Affairs and the Ministry of Environment have strengthened related laws and operate dispute settlement centers such as the "Inter-floor Noise Neighborhood Center", but construction companies are difficult to comply with construction standards due to profitability problems. The construction cost is transferred to the consumers, which affects the rise of the house price. Therefore, it is necessary to have a solution to solve the interlayer noise with a more economical system.

In addition, the interlayer noise problem of the existing apartment building was solved by the understanding of neighboring neighbors and the prevention of interlayer noise, but the noise generated in daily life is blocked through simple facilities and systems to help free activities There is a need for a way to be able.

Furthermore, noise pollution in the living environment such as aircraft noise, railway noise, road vibration, and environmental noise (vehicle noise, construction site / factory noise, etc.) Need to be provided together.
