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.
