Example Embodiment

[0022] Example one

[0023] See figure 1 , Install sponge board 1 on part or all of wall 3 and top surface 4 of rectangular tunnel 6 such as motor vehicle tunnels, motor vehicle tunnels, rail transit tunnels, etc. The thickness of the sponge board 1 is 5mm~500mm, preferably 20mm~200mm, absorb and It consumes the noise generated by the friction between the tires of the motor vehicle 10 and the road surface, and the noise generated by the friction between the train 11 and the track, thereby reducing the noise intensity in the rectangular tunnel 6. The buffering effect. The sponge board 1 is made of a flame-retardant and sound-absorbing sponge with a wave-shaped surface. The appearance color and pattern of the sponge board 1 can be selected according to landscape needs to realize the integration of traffic noise reduction and landscape.

Example Embodiment

[0024] Example two

[0025] See figure 2 , Install sponge board 1 on part or all of wall 3 and top surface 4 of circular tunnel 7 such as motor vehicle tunnel, motor vehicle tunnel, rail transit tunnel, etc. The thickness of sponge board 1 is 5mm~500mm, preferably 20mm~200mm, absorb It also consumes the noise generated by the friction between the tires of the motor vehicle 10 and the road surface, and the noise generated by the friction between the train 11 and the track, thereby reducing the noise intensity in the circular tunnel 7. The sponge board 1 on the wall 3 also has the motor vehicle 10 rubbing the wall Buffering effect at 3 o'clock. The sponge board 1 is made of a flame-retardant and sound-absorbing sponge with a wave-shaped surface. The appearance color and pattern of the sponge board 1 can be selected according to landscape needs to realize the integration of traffic noise reduction and landscape.

Example Embodiment

[0026] Example three

[0027] See image 3 , Install a sponge board 1 on a part or all of the sound barrier 5 of the road or highway 12 on the side of the road. The thickness of the sponge board 1 is 5mm~500mm, preferably 20mm~200mm, to absorb and consume the noise generated by the friction between the tires of the motor vehicle 10 and the road surface. In order to reduce the noise intensity inside and outside the road or highway 12, the sponge board 1 also has a buffering effect when the motor vehicle 10 hits the sound barrier 5. The sponge board 1 is made of a flame-retardant and sound-absorbing sponge with a wave-shaped surface. The appearance color and pattern of the sponge board 1 can be selected according to landscape needs to realize the integration of traffic noise reduction and landscape.

Abstract

The invention relates to a denoising method for reducing noise on a traffic passage through a sponge plate. The technical proposal is that a sponge plate is installed at a proper position of the traffic passage to absorb and consume noise energy and to reduce noise intensity in and out of the traffic passage. The sponge plate with thickness of 5mm-500mm is made of flame-retarding sound absorbing sponge with undulated surface, and the color and the pattern of the appearance of the sponge plate can be chosen according to landscape feature. The denoising method has the technical effects that the sponge plate is porous and elastic; the porous structure enables the sound waves to permeate smoothly and helps to avoid reverberation, and the elasticity enables the sponge to deform to further absorb noise energy, thus effectively reducing noise intensity. The sponge plate is easy to disassemble, wash and replace. The sponge plate on a wall can have cushioning function when a motor vehicle crashes the wall. The denoising method is applicable to the denoising, cushioning and decoration of motor vehicle tunnels, motor vehicle subways, railway tunnels, roads, highways, overhead roads, ground railways and railway overhead passages.

Description

Technical field: [0001] The invention relates to a method for reducing noise in a traffic passage, in particular to a method for reducing noise in a traffic passage by using a sponge board. Background technique: [0002] Existing motor vehicle tunnels, motor vehicle tunnels, rail transit tunnels and other tunnels generally do not take special noise reduction measures, and the walls and top surfaces are generally painted with smooth concrete, facing bricks, and rough paint. Since the wall and top are made of hard materials, they hardly absorb sound energy. The noise generated by the friction between the tires of motor vehicles and the road surface, and the noise generated by the friction between the train and the track reflect strongly and generate reverberation, which makes the "humming" sound in the tunnel The noise problem is more prominent. [0003] Existing elevated roads, expressways, expressways, rail transit elevated and other traffic passages generally set up sound ...
