The Model Experiment And Acoustic Characteristic Study On Noise Barrier

With the development of urban road construction and traffic transportation the noise pollution generated by traffic is becoming more and more serious. Noise barrier is a effective and comparatively inexpensive measure of reducing noise level.lt has practical and important meaning studing on noise barriers which will be benefit to the living quality of the resident in city and continual developing of city construction.The determination of the geometrical size of noise barrier has been dwelt on in the thesis by analyzing the sound attenuation theory.at the same time the structural and landscape design has been discussed and analyzed.At last,to bring forward the new system of computer simulation to analog noise barrier attenuation theory using analogical theory and model experiments by < Acoustic design and measure criterion of noise barriers>in July 2004.The system of computer prediction mainly contains the module of calculating parameter,the module of drawing,the module of calculating,the module of showing result and the module of map example and so on.This system will offer a shortcut to design and predict noise barriers for researchers .It not only has instructal significance and applying value but also is a new research method for the project of our country's noise barrier.
