A mobile road sound barrier includes a soundproof wall, a support, and a base set at the bottom of the soundproof wall. The soundproof wall includes sound-absorbing panels and soundproof panels arranged side by side, with a noise reduction wall between the sound-absorbing panels and the soundproof panels. The outer side of the sound-absorbing panels is coated with a flexible crack-resistant mortar layer, and the outer side of the soundproof panels is coated with a second flexible crack-resistant mortar layer. A noise reduction device is provided at the top of the soundproof wall to filter out the noise removed by the soundproof wall. The support is movably connected to the base via bolts. The bottom of the base has two legs, and the bottom of each leg is connected to a roller. The rollers are placed in the tracks on the base, and the rollers can move the soundproof wall.

The role and application of highway noise barriers
Highway noise barriers consist mainly of two parts: steel columns and metal sound insulation panels. The columns are the main load-bearing components of the noise barrier, fixed to the pre-embedded steel plates on the side of the road crash wall or track by bolts or welding; the sound insulation panels are the main sound insulation and sound absorption components, fixed in the H-shaped column slots by high-strength safety clips, forming a complete highway noise barrier.

Requirements for the Construction of Highway Noise Barrier Foundations
Many factors affect the poor performance of highway noise barriers, such as the relative position, height, and shape of the noise barrier. The horizontal position of the noise barrier should be as close as possible to the sound source, which helps to increase the shadow area of the noise barrier and thus improve the noise reduction. Other conditions remaining unchanged, the shadow area closer to the sound source is larger than that farther away from the sound source.

The principle and types of highway noise barriers
Principles and Types of Highway Noise Barriers Highway Noise Barrier Principles Generally speaking, highway noise barriers can reduce high-frequency sound by 10~15 dB. The height of the noise barrier can be planned according to the distance from the sound source to the receiving point. Assuming the barrier height is doubled, the noise reduction can increase by 6dB. To improve the noise reduction effect of the noise barrier, the noise barrier should be as close as possible to the sound source or receiving point. Highway noise barriers can block the straight-line propagation of sound, allowing diffracted sound to be sufficiently attenuated, but their impact on transmitted sound can be ignored. When the barrier is placed between the sound source and the receiving point, and the barrier is infinitely long, sound waves can only scatter from above the obstacle, forming a sound shadow zone, similar to how light is blocked by an object, forming a shadow.

A simple explanation of highway noise barrier design and height selection
A simple explanation of highway noise barrier design and height selection Highway noise barrier planning and design (1) Selection of highway noise barrier materials and structure Considering its own sound insulation function, the sound insulation ability of the sound insulation screen is generally 10db greater than the required sound level attenuation of the "sound shadow area", so as to prevent the sound insulation screen from affecting the sound propagation, and at the same time prevent water leakage from the holes in the sound insulation screen, and pay attention to the sealing of the structure.
