Prevention of Noise Pollution caused by Highways in Settlement Areas via a Noise Insulation System

Abstract

The noise, which is taken as unimportant at first glance, had become one of the most important factors, causing pollution of environment, because of civilization. Together with the industrial development, mechanization in work places, increase in the number of highways, increased traffic load had made the noise an important problem in pollution and prevention of environment. In this project prevention of the noise caused by the intensive traffic and heavy vehicles in highways in settlement centers is aimed. When preparing the noise barrier system, it is considered that a double glass vacuumed insulation system placed on highway sides can prevent the noise, with the thought that the sound cannot propagate in space. A vehicle had been located and moved in the model road, and simultaneous noise measurements had been performed during the movement on both the road and outside of the double glass insulation system. After the results of noise measurements it is seen that the noise decreases by 14%-17% and reaches to acceptable normal conservation level 57-64 dB (decibel). Double glass insulation system had also prevented the panoroma pollution.
