도로분야 소음 저감을 위한 국내외 ANC 기술수준 및 WBT 분석

Noise generated from the road is one of factors that degrade the quality of life for people. Installing a barrier is an alternative method for reducing road transportation noise. But it has many limitations like the yellowing phenomenon and the surrounding landscape. In order to solve this problem we propose applying active noise cancelation(ANC) to road. We analyze the technical trend and WBT of active noise cancelation in Korea and internationally. The results of study indicates that active noise cancelation has been applied to various fields such as vehicles, airplanes, audio equipment and so on. It needs further research to apply active noise cancelation to the road in order to provide a comfortable lifestyle foe civilians.
