Study on Road Traffic Noise Reduction Method in Apartment

The population density in South Korea is about 500 people per square kilometre (Statistics Korea, 2015). It has the highest population density among OECD countries. In addition, multi-family housing is the representative housing type in South Korea, accounting for more than 70% of the total housing. As a result, road-side traffic noise damage due to urban population density is increasing. In order to alleviate road traffic noise damage, noise reduction measures such as low noise pavement, noise barrier, noise reduction tunnel, etc. are being implemented. However, since the multi-family housing located on the side of the road has more than 6th floor, the existing low noise pavement or noise barriers are limited in noise reduction. Therefore, this study proposes a method to mitigate road traffic noise damage in apartment houses, which are receiver position.
