"The suggested project is aimed at lowering noise level in industrial machines and transportational vehicles that have already been completed as well as for those under construction. In both cases it is necessary to pinpoint the origin and source of the noise emitters and vibrations. One suitable method, besides direct measuring, is a mathematical modelling. This method enables to detect those parts that vibrate the most and then on the basis of calculation, to recommend the way of adjustment without great financial cost needed for experimental testing otherwise. Mastering the mathematical methods calculations of acoustic fields originating in different types of source and by finding out the relative influence of transfer towards the spectrun of noisemay provide suggestions for suitable choise of the vibrating surface shape and also for a correct design of physical-mechanical properties of anti noise cover. Solving special tasks conserning acoustics will give a way to develop autonomous programmes."@en . .
