The present invention relates to a sound barrier, and more particularly, to a sound barrier that blocks or attenuates the transmission of noise from a noise zone where noise occurs to a protected area to block the noise.

Noise is one of the pollution factors that destroy the environment, but it is unique in that there is no material damage to nature such as ecosystem destruction. It does not pose a serious danger to life as it does, but it is unpleasant when it comes to noise.

While air pollution and water pollution are pollutants that are difficult to detect directly by human senses, noise is also called sensory pollution because it can be detected by human sense organs. In addition, there is a problem that urban-life pollution becomes a problem as the energy emission that generates noise is increased due to the increase of human activity in urban life.

Effects of hearing loss and impairment on hearing, psychological effects such as stress and discomfort, disruption of life such as work and learning, physiological effects such as autonomic ataxia and hypertension, decreased fertility rate and birth rate and increased incidence rate There are social effects such as impact on pregnancy and childbirth, lower land prices near noise sources, and lower livestock production.

In general, in order to determine objective criteria as pollution, the volume should be loud or shocking. Sounds with an evaluation noise of 50 decibels or more and high frequency components of 400 Hz or more are considered as noise pollution. It is divided into factory noise, traffic noise, household noise, and aircraft noise depending on the source.

① Factory noise: Noise emission facilities installed in factories are fixed noise sources, not mobile noise sources such as cars, trains, and aircraft. Once installed, the noise source does not disappear, and noise from one discharge facility may continue to damage the surrounding area.

② Traffic noise: Sources are cars and trains, and the noise generated is very high, and the affected area is also extensive. In particular, automobiles are emerging as a major noise source in large cities due to the expansion of the road network and the rapid increase in the number of vehicles.

③ Living noise: The sources of emissions are very diverse, including loudspeaker noise, work noise at construction sites, work noise at small factories, and late night noises at entertainment establishments. Recently, with the increase of population, the sources of emissions due to urbanization and industrialization are increasing rapidly, while the desire for a pleasant living environment is increasing day by day with the improvement of living standards.

④ Aircraft noise: With the recent increase in the number of flight routes and the recent increase in the number of flights, aircraft noise has become a major environmental problem around the airport. Areas where aircraft noise measures are required are those with a weighted equivalent average total noise level (WECPNL) of 80 or more, and the standards in the 'Environmental Standards for Aircraft Noise' target for aircraft noise measures should be below WECPNL 70 or 75 depending on the region.

In Korea, the enactment and promulgation of the Framework Act on Environmental Policy, the Environmental Dispute Resolution Act, and the Noise and Vibration Control Act were enacted and promulgated on August 1, 1990. The amendment to the Enforcement Regulations of the Noise and Vibration Control Act, which was enacted in July 1994, included the construction noise and traffic noise regulation standards in the noise regulation that was regulated solely by the standard of living noise in residential and commercial areas.

In particular, in the downtown area, a lot of noises are generated depending on the nature of the construction of roads and buildings, and because of the characteristics of the noises, they have a lot of influence on the surrounding areas, causing many problems such as complaints.

Therefore, in order to prevent noise caused by the construction, a separate soundproof wall is installed for the construction of the building.

However, in the case of road construction, the soundproof wall must be moved and installed according to the movement of the construction area separately. Therefore, the installation of the soundproof wall becomes cumbersome, and most of the construction proceeds without the installation of the soundproof wall. There is a problem that the noise is transmitted to the surrounding area without filtration.

The present invention can effectively block the noise generated from the noise source while moving together in accordance with the movement of the noise source in order to solve the problem that the noise source can not properly block the noise generated from the noise source by moving, such as construction on the road as described above. The present invention provides a mobile soundproofing device.

The present invention has been made in order to achieve the object of the present invention as described above, the present invention includes: a soundproof unit having a soundproof wall for blocking the transmission of noise generated from the noise source; A moving part coupled to the soundproof part to move the soundproof part together as the noise source moves to block the noise generated by the soundproof part; It provides a mobile soundproofing device comprising a.

The sound insulation part includes a support frame for supporting the sound insulation wall.

The support frame is characterized in that it has a cross-section of the 'H' shape to have a groove portion into which the soundproof wall is inserted.

The support frame is connected to the moving part.

The moving part may include a wheel installed in the support frame.

The moving part comprises a driving part for driving the movement.

The moving part may further include a connection part connected to the noise source so as to move corresponding to the movement of the noise source.

Hereinafter, a mobile soundproofing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.
