Things To Know About Noise Barriers In Highways

It is normal for people to get stuck in traffic amidst irritating sounds. People traveling across long distances may notice various types of noise abatement solutions in the form of large walls adjoining the roadway. These noise abatement solutions are also known as highway sound barriers which aid in controlling noise pollution.

To protect people from noise pollution and traffic snarls, noise barriers are an ideal solution. To be precise, noise barriers are crucial not only on highways but also on various types of subways and railway tracks.

Based on the view of medical practitioners, noise pollution is the primary reason behind stress and anxiety. Moreover, noise emanating from highways and motorways can adversely affect animals and birds. Here are some important things one should know about noise barriers on highways.

Working Mechanism of the Noise Barriers

Quite interestingly, noise barriers along with sound walls are the subject of research for many federal and state discussions. Conventionally, noise barriers on highways were usually made of brick, metal, and concrete.

These materials played a crucial role in eliminating noise pollution on highways. In most cases, neighborhoods and business districts usually surround the highways. Installing noise barriers can save local neighborhoods and business districts from noise pollution.

Need for Highway Noise Barriers

The primary reason behind the need for highway sound barriers is the increase in various ailments across people. From high blood pressure to cardiac stroke, noise barriers can help prevent a wide variety of problems. Nowadays, noise barriers are made of acoustic panels to decrease the low and high-frequency noise levels.

However, there are huge advancements in noise testing and sound dampening nowadays. Researchers are on the lookout for sustainable materials to dampen sound on the highways. Quite impressively, noise barriers nowadays use mineral wool between various layers of perforated fiberglass. Mineral wools are ideal for absorbing unwanted sound emanating from traffic snarls.

Noise is an Environmental Issue

Noise is an environmental disaster. Therefore, authorities should keep in check the increasing sound levels. Noise is also one of the main reasons behind a majority of physical and psychological illnesses.

Thanks to highway noise barriers, people can now continue their work in a peaceful environment. Noise is also referred to as acoustic pollution.

Noise decreases the overall quality of life. Now one can decrease the overall exposure with proper noise barriers. One of the key highlights of noise barriers is that they don’t harm the natural environment. Moreover, the panels of the noise barriers can be easily covered with artificial materials.

Benefits of using Rubber in Noise Barriers

Here are some benefits of using rubber in noise barriers.

  • Rubber aids in insulating sound
  • Rubber is pretty resistant to bad weather conditions
  • Rubber is highly flexible and doesn’t get damaged during collisions


No doubt, highway sound barriers are playing a crucial role in controlling noise pollution. With noise barriers, authorities can make the city life a better place to live in.
