ANALYSING ACOUSTIC PROPERTIES OF A SUBWAY TRACK

Popis výsledku v původním jazyce

This paper describes laboratory measurement of acoustic properties of subway track samples, with the main focus on the change of the basic material of selected components of a rail fastening system. They were identical in shape, the only difference was in the material used. A suitable methodology based on measuring the acoustic response to mechanical shock was developed for laboratory measurements. The measured data was assessed with an appropriate mathematical apparatus based on signal analysis methods in the time and frequency domain. Based on the tests performed, the acoustic properties of the structures examined were determined. A comparison of acoustic properties of the tested samples and recommendations for practical applications are also covered.
