In this study characterization of noise reduction in industrial environment was contrasted with noise reduction on roadside. Many study determined noise reduction on highway, but very rare study on industrial environment. The aim of this study is to determine noise reduction of tree belt in an industrial environment at an urban forest of cement factory in Cilacap Indonesia. The study compares five different scenarios of tree height; 6-meter, 10-meter, 15-meter, 20-meter and 30-meter height. To determine the net noise reduction effect termed as relative attenuation, an amplifier was placed 1 meter in front of the trees, and the sound pressure level was placed behind the tree belts at four different distances; 5, 10, 15 and 20 meters. Relative attenuation from tree belts areas subtracted with relative attenuation at equal distances over open ground. Open ground is places without tree belt which taken as control. In this work, the important factors that affect the noise reduction were taken into account, i.e. species, height, a number of trees and distance. From the research, we found that noise due to industrial environment have different characterization with noise on the highway. Therefore further research is needed to determine the design of experiments in an industrial environment to analyse characterization of noise reduction with better accuracy.
