레일용접에 의한 소음저감 효과

초록

There are three examples of noise reduction test by rail welding. One of them is tested at electric car running area and another is tested at expansion joint and long welded rail and the third is tested at open deck bridge. We can know from the result that the noise reduction effect of rail welding is very different to the type of track and the car. The condition of the test has some differences, but it may be useful reference of noise reduction.
