Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] like Figure 1-Figure 3 As shown, a transparent sound insulation device for high-speed rail includes a fixed frame 1, and a sound-absorbing device is arranged on the fixed frame 1. The sound-absorbing device includes a sound-absorbing layer 5, and the sound-absorbing layer 5 includes a multi-layer sound-absorbing board 6; the sound-absorbing board 6 includes a sound-absorbing substrate 602 on which a number of resonance holes 601 are uniformly arranged. The sound-absorbing board 6 is used...

Abstract

The invention discloses a permeable sound insulation device for high-speed railway, which comprises a fixing bracket, a sound-absorbing device is arranged on the fixing bracket, the sound-absorbing device comprises a sound-absorbing layer, and the sound-absorbing layer comprises a multi-layer sound-absorbing board. The sound-absorbing board comprises a sound-absorbing substrate, and a plurality ofresonance holes are uniformly arranged on the sound-absorbing substrate. The resonance hole is connected with the sound-absorbing base plate, the structure of each sound-absorbing plate is different,and each sound-absorbing plate absorbs sound waves with different frequencies. By setting the device, the sound energy can be absorbed, the noise can be reduced quickly, and the environmental pollution can be reduced; the device can isolate the sound in the vicinity of the railway, reduce the distance of sound transmission.

Description

technical field [0001] The invention relates to a sound insulation barrier, in particular to a transparent sound insulation device for high-speed rail. Background technique [0002] In recent years, the rapid development of high-speed railway construction has brought people fast, comfortable and convenient travel, but the noise pollution generated by the operation of high-speed trains has also caused great harm to the lives of residents on both sides of the railway line. Impact. According to reports, in November 2008, the Building Environment Testing Center of Tsinghua University actually measured that when the 300-350km / h EMUs of the Tianjin-Beijing Intercity Railway were running, the actual peak noise at a distance of 15m from the track on one side of the line could reach 90dB. Exposure to such intensity of noise for a long time will cause great harm to personal health. For controlling this environmental noise pollution, people have thought many ways, and a kind of effec...
