| Abstract: | This article describes the noise control of the circulating cooling tower of the jiujiang environment garbage power plants at shuangliu in Chengdu.we set up noise barriers by means of sound propagation and conduct the theoretical calculations of the acoustic sound barrier design.After the sound barrier is completed,the noise value of the unit outside the plant boundary 1 meter achieves the national boundaries of the factory noise emission standards.By detailing experimental data and establishing the graphics,It furtherly validates the theoretical formula and the scope of protection for sound barrier. |
