Review of New City Viaduct Noise Barrier

Noise not only makes people worry, sleep disturbance, hinder learning to work and rest, affect human health, and it is difficult to completely eliminate. Sound barrier is located in the sound source and the sound receiving point between the structure with shielding enough surface density of sound, built finite noise barrier of sound source by both local area can make the operation noise source in the dissemination process has a significant additional attenuation, which weakens the noise influence in certain areas where the recipient within, to improve the quality of acoustic environment of the surrounding environment. The present research situation of new sound barrier and the research content of new sound barrier are summarized. The theoretical reference for the further development of new sound barrier is provided.
