The importance of acoustic and vibration measurements and analyses are unambiguous as from the point of view of human health protection, so from the point of safety, lifetime and reliability of measured establishment, eventually the construction. The precise analysis provides detection and identification of noise and vibration sources and thereby their reduction as well. Theoretical study of this problem, the developed procedure of measurement and analysis and demonstration of real experimental measurement of acoustic-vibration parameters different by various types of rail wheels are demonstrated in the article.
