Title: A NEW SOLUTION FOR THE RAILWAY NOISE REDUCTION
Keywords: Noise, Railway noise reduction, Noise absorbers, Noise barriers.

Abstract: A new solution of the railway noise reduction is proposed in this work. The aim of this construction is to “catch” and absorb the noise radiated form the wheel and railway close to the contact between them. It was created an experimental set-up and the results show high level of reduction of the noise at frequencies of the rolling noise. On the base of the analysis of the results some conclusions about effectiveness of the solution are done.
