Description

Apparatus for noise interference

The present invention relates to a noise interference device, and more particularly, to a noise interference device for a noise barrier for a road to block and reduce noise transmitted from the outside by being installed on a roadside, a railroad track, or a dense place where houses are crowded. .

Noise refers to the vibration of the frequency band that makes people uncomfortable at an audible frequency in which humans can hear the vibration of air, and this noise is widely distributed in the surroundings of our lives such as roads, railways and general industrial sites.

Noise has a great effect on human life and, in severe cases, is classified as pollution which impedes human life. Therefore, roads, railways and noisy industrial sites should be soundproofed for those living in the vicinity.

In general, neighboring residents suffer a lot of inconvenience due to the noise generated by the traffic of numerous vehicles around roads and highways.In order to solve the noise pollution, it is generated by the traffic of vehicles on roads, especially on the structures on both sides of the highway. Soundproof walls that provide sound insulation by absorbing or reflecting radially propagated noises are provided.

Since the noise generated around the road propagates radially straight from the noise source using air as a medium, most of them are absorbed or reflected by the sound barrier, but some of them are collided and diffracted and passed over the sound barrier by the sound wave. The diffracted noise that has just passed propagates directly to the residential area, causing noise pollution.

Recently, with the development of the noise and vibration field, researches for reducing the diffraction noise passing through the soundproof wall have been actively conducted, but until now, no device with better noise reduction effect has been developed than the method of increasing the height of the soundproof wall. It is true.

However, the expansion of the height of the soundproof wall is subject to a lot of restrictions due to the violation of the viewing rights, there is a problem that not only easy to install the soundproof wall in addition to the existing soundproof wall itself, but also increases the use of additional facilities. Furthermore, it causes many problems, such as causing psychological anxiety or violating the right of view to residents or passengers using vehicles. In addition, when the soundproof wall is installed in a structure that is affected by a load, such as a bridge, it should be installed as low as possible to reduce its own load in order to secure the structural stability of the bridge and to ensure the stability of the strut and lower foundation structure. In this case, residents living in high-rise apartments in nearby areas are constantly complaining about the noise of the vehicle.

In addition, the conventional noise interference device has a problem that the installation cost of the soundproof wall in which the noise interference device is installed is increased due to not only a very complicated structure but also a large installation cost, and according to the time and process required for the installation work. Due to the increased installation air, there was also a problem that the efficiency of the installation work is reduced.

In addition, the conventional noise interference device can solve some of the problems with the noise, but the structure of the noise interference device has a problem that is eroded by rain or snow or other foreign matter accumulate.

In order to solve the above problems in the present invention, the purpose is to effectively prevent the transmission of noise through interference and diffraction between the noise, through the reduction of the soundproof wall height, to secure economical and structural stability, and Another purpose is to protect the sound absorbing material and internal structure provided inside the noise interference device by preventing the inflow of foreign substances such as rainwater or snow in advance, and to install the soundproof wall firmly and easily to improve the excellent functionality and work efficiency. .

As described above, by installing the noise interference device according to the present invention on the top of the sound barrier, the noise is blocked by the sound barrier and at the same time the noise is hit by the noise interference device is diffracted, absorbed by the sound absorbing material inside the noise interference device, inside The effect of reducing the noise is excellent due to the interference phenomenon in which sound waves of noises introduced into each other collide with each other.

Furthermore, it is possible to reduce the height of the soundproof wall by forming an interference area at a position above the height of the installed soundproof wall, and by achieving the height reduction of the soundproof wall, it is possible to secure structural stability in the foundations and lower foundations of bridges and structures. .

In addition, by removing the hole on the upper surface of the noise interference device, it is possible to minimize the damage of the sound absorbing material and the internal structure provided inside the noise interference device by blocking the inflow of various foreign substances such as rainwater or snow. It is a very useful invention that can be easily installed to provide excellent functionality, field adaptability, and work efficiency.
