Development of methodologies and devices for noise protection of urban envirnoment

Serbian Law on Environmental Noise Protection (Offic. Gazette of Rep.of Serbia No. 36/2009) provides measures of environment protection. However, many of the listed measures do not have support through definition of standards and procedures, development of software and protection means. This project aims at removing some of listed deficiencies. The first part of the project comprises development of methodologies of exposure of urban population to noise on the basis of noise source (transport noise, industry noise etc.), and development of software modules that will support application of the developed methodology for strategic noise mapping, as well as procedures for design of noise protection plans. The methodology will then be tested in pilot towns. The second part of the project will deal with development of procedures and means for noise removal. Methods for active reduction of noise at sources, as well as methods of passive noise removal by sound barriers and absorption materials will be analyzed. The work will include measurement of absorption coefficients of waste material like wooden waste, PET packaging, used tires and other. Within this task, a sound absorption laboratory will be developed. The third part of the project comprises design of means for active and passive noise protection. On the basis of previous research results, modular sound absorption barriers and sound absorbers for various applications and exploitation conditions will be designed and tested.
