The invention relates to a sound-absorbing panel for a railroad bridge. The sound-absorbing panel for the railroad bridge is characterized by comprising a hollow support framework, wherein a sound-absorbing panel body is arranged in the support framework; one surface of the sound-absorbing panel body clings to the front panel of the support framework and the other surface of the sound-absorbing panel body is tightly pressed by an iron wire framework; through holes are formed in the front panel of the support framework; the thickness of the support framework is 6-9cm. The sound-absorbing panel disclosed by the invention is long in service life, and the sound-absorbing effect is the optimal. The sound-absorbing panel does not need to be exchanged often, so that the sound-absorbing panel has the highest cost-effectiveness.
