Study on computer analog of noise barrier prediction system

Noise pollution has been a cosmopolitan problem,which in company with water pollution and air pollution is making three primary infecting sources at contemporary era.Along with high speed of city building and city's public traffic raiding development,which make the ride difficulty obviously alleviated.But noise pollution is serious gradually,the main factors of noise pollution are noise source、transmitting path and reception point.Noise inevitablly happens,no matter which measure we have taken at noise source and transmitting path.So valid noise controlling method is build barriers.The insert loss of noise barrier directly influences attenuation of noise.The paper introduces structure and particular function of software of Computer Analog of Noise Barrier Prediction System.It is a new method for design of noise barrier.
