In addition, noise reduction and soundproof wall installation identification are revealed by using luminous fluorescent objects and reflectors so that they can be identified from a distance even at night.

Description

Noise-absorbing device {A Noise-absorbing Device}

The present invention relates to a noise absorbing device, and more particularly, by reflecting and refracting the process in which the wavelength and frequency of wave sound (noise) generated from a sound source are transmitted as molecular kinetic energy through an opposing angle (reflection angle) to maximize It relates to a noise absorbing device that absorbs many wavelengths of sound (noise) and induces it to pass through a collected long tube.

Recently, civil complaints have frequently occurred between neighbors due to noise pollution and scattering dust generated in the surrounding environment.

In particular, noise generated in dense urban areas, industrial production sites, roads, railroads, and airports is causing civil complaints and disputes by harming health and the environment.

Due to this problem, in residential areas near roads with frequent vehicle traffic, including schools adjacent to roads, soundproof walls are installed to maintain a pleasant residential environment by blocking noise from horns or noise generated in the course of driving vehicles from being transmitted to residential areas. installed In addition, it is necessary to install such a soundproof wall in the central partition wall of the road.

As types of sound barriers, there are known see-through sound barriers that reflect noise generated on the road back toward the road to block the propagation of noise to the outside of the road and sound-absorbing sound barriers that absorb and eliminate noise generated on the road. Although it is inexpensive, the noise blocking effect is low, so there is a disadvantage in that a high blocking wall must be installed. Therefore, in recent years, a sound absorbing sound barrier having excellent noise effect and a see-through type blocking sound barrier are combined and widely used.

The above-mentioned see-through sound-absorbing sound-proof wall has a sound-absorbing material embedded inside the transparent sound-proof wall,

Thanks to the beautiful luminous material, it helps with safety by giving liveliness to eyes tired from city scenery and long-time driving. In addition, noise generated from the road is absorbed through the sound absorbing material, while noise is reduced through resonance inside the cavity.

On the other hand, in order to maintain soundproofing and sound absorption, there are rock wool, styrofoam, glass wool, asbestos, etc., which are mainly used as interior materials.

However, rock wool, Styrofoam, glass wool, and asbestos are products made by solidifying and foaming chemical materials such as lime, potassium silicate, serpentine, amphibolite, and glass liquid, so they are easily burned or generate a large amount of harmful substances to the human body, property, and environment. had a disadvantage that caused great damage to

In particular, due to the nature of the material, rock wool and glass wool, which are used as soundproofing and sound-absorbing materials, generate dust, itching, respiratory disorders, and carcinogens, while Styrofoam emits harmful gases (cFc) in the event of a fire, which adversely affects the ozone layer and damages human life and property. The rock wool was accompanied by dust, carcinogens, and respiratory disorders.

In addition, even after the interior materials are installed in the building, environmental harmful substances generated from the materials themselves are harmful to the health of residents when living in them, and when demolished, a large amount of industrial waste is generated because they cannot be recycled, and construction is difficult because the material itself is heavy. It was uncomfortable.
