Depending on the speed up of railway noise problem has become increasingly serious. In general, under the same conditions when the vehicle speed is 300km/h in a 400km/h increases, it is known that an increase in the noise level of 6 to 7dB. Railway Noise can be reduced by improving the vehicle and the track system. Also, the noise barrier and sound absorbing block may be a valid alternative to reduce railway noise. Here we propose a construction method of absorbing blocks are removable to allow maintenance.
