The DW barrier is a green product design. It help absorbing the noise generating from vehicles on a heavy vehicular traffic area such as highway and railway.There are
receptors inside the barrier to recieve the soundwave and turn it from fluctuations into electrical energy. These electrical energy will collect by a electricity box and send to a
distributing box. Finally, the distributing box will distribute the electricity to the highway signboard, lamp post and traffic signal board to provide power. And for the barrier
