What are the different types of noise barriers?

There are a number of types of noise barriers that are regularly used to reduce noise pollution. Noise barriers are any external structure used to block sound waves from roads, railway lines and industrial areas. They can be made of natural or artificial materials. To make these barriers effective, various factors must take into account. Building and installing noise barriers are expensive. Especially barrier walls that run along interstate highways can mean miles of buildings. For this reason, noise barriers are most often designed in areas where roads pass through residential areas.

Scientific research has shown that life with excess noise can be harmful to the health of the population. Excessihluk V can lead to hearing problems, increased blood pressure, sleep problems and increase overall stress levels.

There are two basic types of noise barriers. The first are made of ground, on site. This is the least expensive option. The country is to the displayOznii on the site of work and without costs, so the only price is the work of the construction of a barrier wall.

Often there is not enough material at work. In this case, real estate owners, besides roads, often allow the use of some filler material from their assets. This provides another advantage of reducing the ground floor level, which further reduces the noise on the land.

barrier walls can also be built of artificial materials. These can be concrete, steel, plastic or composite materials. These materials are very effective in preventing sound waves from traveling from the road, but have other disadvantages.

The main disadvantage of barriers of noise produced are costs, aesthetics and the need for specialized drainage solutions. The cost of several kilometers of noise barriers can quickly become astronomical. Aesthetics is also a concern because kilometers of steel or concrete walls can be very unattractive. Finally, uThe noise barrier room next to an existing road can cause changes in the outflow on the road, leading to water association during rainy weather. All these factors must be carefully considered when building noise barrier.
