Antonov A.I., Zhdanov A.E., Ledenyov V.I.Automation of Noise Fields Calculation in Industrial Buildings // Scientific article. Journal "Transactions of the TSTU", vol. 10 , Tambov. TSTU publisher house , 2004. (pdf-file) Abstract: In planning the noise protection strategies in industrial buildings, the main component is calculating the noise field energy parameters. Efficiency of noise protection depends on the degree of objectivity of a mathematical model, describing the sound energy distribution over a room with different volume and planning and acoustic parameters on the basis of the real conditions of the noise field foundation. In this article an automatic estimate program for a noise condition when planning the noise protection strategies, is presented. Calculation of noise levels in a room is made by the statistical energy methods.

Journal "Transactions of the TSTU", vol. 10 , Tambov. TSTU publisher house , 2004. (pdf-file) Abstract: The process equipment, placed in manufacturing buildings, essentially
influences the process of formation of reflected noise fields of rooms. The presence of the equipment results in reduction of an average length of free path of sound beams and change of average factors of a sound absorption of a room. In the end it has an influence on distribution of sound-levels pressure. The report deals with the technique of an estimation of average factors of a sound absorption inside the premises with the equipment based on use of method of ray tracing.
