A sound-absorbing panel of a lower portion of a vehicle for a high-speed train comprises: an upper plate unit; a lower plate unit; and a partition wall unit. The upper plate unit is attached to a lower surface of a vehicle unit of a high-speed train. According to the present invention, the lower plate unit is spaced downward from the upper plate unit by a predetermined distance to have a resonance space between the upper plate unit and the lower plate unit and has a plurality of fine holes to enable the resonance space to be exposed to the outside, and the partition wall unit is interposed between the upper plate unit and the lower plate unit to maintain a distance between the upper plate units and divides the resonance space in plurality.

    고속열차용 차량하부 흡음패널은 상판부, 하판부 및 격벽부를 포함한다. 상기 상판부는 고속열차의 차량부 하면에 부착된다. 상기 하판부는 상기 상판부로부터 하부 방향으로 소정 간격 이격되어 상기 상판부와의 사이에서 공명공간을 형성하며, 복수의 미세홀들이 형성되어 상기 공명공간을 외부로 노출한다. 상기 격벽부는 상기 상판부 및 상기 하판부 사이에 개재되어, 상기 상판부와 상기 상판부 사이의 간격을 유지하며, 상기 공명공간을 복수로 분할한다.
