The concept of highway noise reduction barriers is not new. But as the technology has advanced there have been many changes in the height way noise reduction options. The primary focus of such options is to divert the traffic noise effects that usually come from the highway. These barriers restrict the direct sound path between the receivers who get exposed to the sound that the highway created.
However, there are many parameters on which the design of the noise barrier needs to be decided. Talking of which aesthetics, noise mitigation, construction, and cost are a few of them. Also, the length and height of the noise barrier are determined as per the design.
About the noise barriers of highways:
Initially, the concept came into existence in the year 1970. There was a standard concern reflective barrier type which was created. Later as the technology got developed, there was an absorptive noise barrier created too. Both the designs primarily focused on reducing the noise so that residents don’t get affected but the difference that can be noted is the way it functions. In the case of Reflective noise barriers, the noise gets direct and gets back in traffic away from receptors. In the case of absorptive noise barriers, the barrier removes the noise from the surrounding itself.
Understand the working of Highway Noise Barriers Work:
The sound walls and the highway noise reduction barriers are still the subjects for state, federal, and local studies and discussion. The blockades were made using brick, metal, and even concrete to reduce the loud noise which would be generated by the highway traffic. Such a highway sound barrier wall is crucial to ensure the freeway sounds which seem to be offensive get penetrated away from the business areas and local neighborhoods.
Since the material used for creating the highway walls was not quite tall to control the sound, it was then the barriers were used. As the reflective concrete walls on both sides of the highway resulted in a bounce back of the noise, the level increased when the reflection occurred. That is why outdoor noise control is crucial with the commercial and residential businesses if they are located close to the traffic areas.
Advantages of Highway Noise Barriers
- Fewer headaches
- Good rest
- Better focus
- Proper sleep
- Improvement in productivity
- No less hearing problem
The highway noise reduction of today’s time is designed with absorptive panels which are customized easily and even pre-engineered for every application and site. Besides, the design of the wall is made in such a manner that it has a protective UV coating. This reduces the chance of rotting, rusting, and even deterioration in extreme temperatures.
Highway noise reduction barriers are more like road umpires. They are noticed only when something is wrong. While determining whether the noise reduction barrier is required or not, the state needs to consider the federal laws along with their policy.
With the hassle-free working explained and the advantages, no doubt installing such a barrier would benefit the receiver who usually gets exposed to highway sound often.
