The application of the noise mapping technique in the complex industrial environment

Noise is a major factor in dissatisfaction with the environment in residential areas, especially in a potentially tourist, coastal region. When the noise problem originates from the 24-7 working cement plant, solving solutions demands wide spectrum of the known noise protection measures, but the outcome is always doubtful. This article presents applications of the noise mapping technique as an efficient tool in the environmental protection master plan of the Holcim (Croatia) d.o.o cement plant. In order to quantify noise effects of the particular noise sources inside the cement plan, the extensive noise measurements inside have been performed. The visualisation of the existing noise levels inside and around the plant was performed with the sound immision contour lines overlaid upon geographical information. In order to improve the efficiency and accuracy, the level of detail of the complete noise mapping process was adapted to the purpose and desired level of detail of the entire noise protection master plan. The detailed noise map was taken as the basis for the various action plans and subsequent public consultation. The quality of the modelled action plans directly depends on the quality of the input data and the methods used in every step of the noise mapping process. The proper balance between the level of detail and the exactness among the different steps in the noise mapping process has been noticed. Such balanced action plans require a deep insight into the costs/benefits of alternative noise protection measures including possible integrated environmental approach.
