Noise protection fences guarantee comfort

Noise shield

What is the noise everyone knows. Wherever there is a man, noise sounds accompany him everywhere. Natural phenomena (thunder, rain, wind), as well as everything created by man (cars, factories, elevators, railways, subways and other goods), are accompanied by sound effects. Noise fences will help to cope with unpleasant decibels.

No one doubts that noise (hum) is the essence of our life and should be perceived as reality. But all is well, if the noise does not exceed the permissible values. Otherwise, especially residents of megalopolises, are subject to noise discomfort and as a result, numerous stresses and illnesses.

If it is impossible to eliminate all noise sources, then it is quite possible to reduce their level to the minimum (optimal) level by applying noise absorbing fences.

Noise features

Fuzzy vibrations of sound, which are called noise, are characterized by:

• amplitude;
• frequency;
• loudness of sound.

A strong influence on the noise level that we hear in a room is made by the distance to the sound source, humidity, air temperature and even wind.

How does the height of the fence and the distance affect the noise level

Tip! As the distance to the noise source increases, the sound pressure level decreases by 6 dB.

Types of fences

Classification

All fences that are designed to combat noise are divided into:

• sound reflecting;
• noise absorbing;
• combined.

What is the better and cheaper fence? Read about it below.

Sound reflectors

Sound reflective fences are designed to reflect sound waves, and are made from:

• concrete;
• bricks;
• polycarbonate;
• glass and other material.

Noise absorbers

Noise barriers

The noise-absorbing fence is a structure that has the properties to reduce the intensity (extinguish) of a sound wave. Panels of such fencing can be:

• iron;
• aluminum;
• plastic.

A noise-absorbing material is inserted between the panels of such a fence. For this, mineral wool (based on basalt fiber), a well-defined structure and an exact specific weight is most often used.

In some models it is used as a filler:

• polyester wadding;
• centrifuged cotton (mineral);
• fiberglass;
• hydrophobic cotton (polyester).

Such fillers have a pronounced sound characteristic.

Photo noise insulation fence

Noise shield

Noise insulation fences combined type represent a noise shield. It combines all the characteristics of reflective and absorbing protective structures. By and large, the role of an acoustic screen can be performed by any building, structure, or object of natural origin: a mountain, an earthen wall, a forest plantation, a forest, etc.

Design features of fences

The noise protection fence constructively consists of perforated acoustic panels, which have a noise absorbing effect. The panels are fixed between I-beams, which are installed vertically. You can also install panels between other fixation elements. To achieve the required height, sound-absorbing panels are installed in several rows. The mounting of the supports can be flange (on anchor bolts) or can be embedded in the foundation.

A sound-proof fence consists of acoustic panels, the basis of which is a cladding relief profile of thin metal, as well as fibrous, porous materials that absorb sound. The panels on the ends are sealed securely. Facing can have both unilateral perforation, and bilateral.

Installation of noise insulation fence

Installation of anti-noise fence

To reduce noise from industrial facilities or other production, you can use soundproof fencing. Such a fence is significantly different from ordinary fences. The main sound insulation function is performed by an interlayer of high-quality material that is mounted between the rows of panels.

To mount a noise insulation fence, you need to contact a specializing company or install a fence with your own hands, as shown in the video. For this, the following instructions are provided.

1. You should know that the main indicator, which is characterized by noise protection fence, is the degree of noise reduction. Therefore, before installing the fence, it is necessary to analyze the sources of noise and determine which sound is most harmful to your well-being;

Tip! In order to make an accurate decision, it is necessary to contact the health service for a real measurement of the noise level.

1. Before installing the fence, it is necessary to calculate the cost. To do this, consider:

• the required size of the anti-noise screen;
• in what climatic conditions will be used;
• what efficiency is required in noise reduction;
• soil characteristics and other special conditions.

1. Carefully measure the length of the section around which you want to install a fence;
2. Calculate how many noise panels will be needed for the fence;
3. In the next step, it is necessary to prepare the holes for the posts, which will serve as the supporting structure;
4. Pillars in the holes are fixed with concrete;
5. Next to the supporting posts are mounted soundproof panels on one side. After installation of the rails, a polyurethane coating is installed to protect the wood from climatic exposure.

You can install a noise barrier in front of an existing fence.

Tip! You should not save on the quality of sound insulation material. If you use less quality material, the desired effect of sound absorption will not be achieved.

Total

Sound-insulating fences are an excellent and optimal solution for minimizing increased sound effects from various sound sources. With the help of such a fence, you can significantly increase comfort and coziness in your home, which ultimately will have a positive effect on the general well-being and health of residents (read also the article “Slate Fence - the most economical option”).
