Highway Sound Control Barriers 101

The purpose of a highway sound barrier is to reduce the impact of traffic noise along the roadway. Noise barriers obstruct the direct flow of sound from the source on the roadway to the receiver who is exposed to it. The ability to reduce noise, aesthetics, economics, and constructability, as well as structural capacity against wind and seismic stresses, are all important factors to consider when designing a noise barrier. Acoustical factors, aesthetics, and cost all influence the height and length of a noise barrier Furthermore, the noise barrier’s structural design must adhere to set guidelines.

The highway sound barrier, in theory, would prevent sound waves from penetrating the community behind the walls.

The truth is that the noise is exacerbated by the highway walls, which bounced off the barriers and blasted into surrounding neighborhoods.

The use of absorptive materials that reduce sound waves rather than amplifying and bouncing them off the walls makes for a more efficient highway sound barrier.

Noise Barrier Walls on Highways

To reduce noise from Interstates and busy highways, architects, developers, construction, and engineering teams employ a range of strategies.

The material, aesthetics, positioning, and arrangement all have a role in capturing and killing sound.

Highway Noise Reduction Site Planning

Increasing the amount of space between the sound maker and the receiver is one of the most common uses of site planning.

However, in a residential setting, achieving this goal without purchasing land near the highway and removing structures is not always simple.

Noise levels can be reduced by using the buildings as storage or by constructing new ones with a different orientation.

Material that absorbs noise

The type of noise-absorbing material used on buildings or walls affects how loud the sound is and how high the frequencies are. Consider how much material would be used for highway walls near residential areas.

Textures, trim, and windows are used by architects and designers to break up the sound wave as it enters the building. Solid walls and other aspects can be used by interior designers to assist minimize noise even more.

Highway Noise Barriers Have a lot of advantages

  • Noise that causes tension is reduced
  • There are no reflected sound waves, and the high and low-frequency waves are captured
  • It does not reflect as well as concrete
  • Reduces the environmental and community’s physical, mental, and emotional effects of noise
  • For aesthetics, a range of design patterns and wall colors are available
  • Protects travelers from reverberations that occur when the barriers are crossed. permitting access from both sides of the road
  • There’s no need to be concerned about rotting, rusting, or animal nests
  • The panels were built to withstand major storms
  • The lightweight nature of these materials enables the construction of walls in applications where weight is a constraint
  • It is possible to install it with as few as three team members
  • Teams can take them down and reconfigure them for use in different regions because they are mobile and adaptable


Today the world is constantly surrounded by unwelcome noise, whether it’s from noisy neighbors or traffic. According to recent World Health Organization (WHO) studies, noise pollution has a negative influence on both mental and physical health. Hence, noise barriers must be typically imperforated to prevent sound from passing through gaps and have a minimum mass of 10kg/m2 to prevent noise from flowing through lighter materials. Aesthetics, privacy, size, cost, and upkeep are all important considerations in addition to the ability to suppress sound.
