초록
Ballast track on subway and railway has been used by lower cost of construct and easy to maintain. The ballast track has been used for distribute the dynamic load of the railway cars. Ballast track is known to lower noise level in cabin noise and radiated noise than slave track by the less noise emission. However, sound absorption property of ballast track has not been reported. Therefore, in this study, the normal sound absorption coefficient was measured for the ballast with different size, layer depth, and array of grinded ballast with each different size. From the experimental results, it was found that the smaller ballast had good sound absorbing performance.
