"The project is aimed at utilizing and evaluation of one of the most effective ways of noise and vibration reduction, which is reduction of noise and vibration directly at the source of them. As machine part vibrations act as a source of noise radiation, appropriate absorptive dampers will be searched for, which will reduce machine part vibrations and reduce noise at the same time. The task is to estimate the ability of vibration and noise absorptive dampers of various types and parameteres to damp vibrations and noise efficiently. It is necessary to find out and to elaborate a methodology for the laboratory research of dampers, that would determine the type and location of the damper, wouldlead to its optimizatiestimate its efficiency. Modal and acoustical properties of a component will be determined with and without the damper. The substance of the whole project is then the specification of appropriate absorptive dampers of representative machine parts and determination of methods for their efficien"@en . .
