A traveling wave type intense sound experiment chamber comprises a horn, an experiment chamber body and an exhaust chamber, wherein the horn is sequentially connected with the experiment chamber body and the exhaust chamber; a chamber door is arranged on the experiment chamber body; the experiment chamber body adopts a dual-layer structure and is divided into an inner chamber and an outer chamber, the inside of the inner chamber is a traveling wave space, an interlayer between the inner chamber and the outer chamber is filled with fine particulate matters for sound insulation, and the fine particulate matters are quartz sand or metal particulates; the exhaust chamber is connected at the tail end of the experiment chamber body and communicated with the experiment chamber body, silencing wedges, a silencing channel and an exhaust pipeline are arranged in the exhaust chamber, the silencing channel is arranged behind the silencing wedges and formed by arranging multiple separating plates in a staggered manner, a space in the exhaust chamber is separated into an S-shaped air flow channel by the multiple separating plates forming the silencing channel, and the exhaust pipeline is arranged at the tail end of the silencing channel and penetrates through the wall of the exhaust chamber to extend out of the exhaust chamber. With the adoption of the experiment chamber, intense sound noise reduction, sound insulation and intense sound effect experiments on aerospace materials and components can be performed.
