Acoustic Barrier for Railway

Model NO.: Tianshun Application: Protecting Mesh, Screen, Construction Wire Mesh, Decorative Mesh Origin: Hebei Province, China Material: Low Carbon Steel Plate Trademark: Tianshun Sound Barrier
With the development of urbanization, sound from all directions is more and more variable and intrusive. So we need to take measures to prevent our normal life from these sound injury as far as possible.
We are a professional manufacturer of the sound barrier with professional technical team. The sound batrrier can effectively reduce the influence on people. It is more and more popular by customers.

Principal: Insert  a facility between the source and the receiver, making the sound wave propagation have a significant additional attenuation. Thus weakening the influence of the noise within a certain region, such a facility is called the sound barrier.

Application:  Nowadays, the sound barrier is mainly used in highway, composite elevated roads, urban light rail subwayand other transportation facilities in the municipal acoustic noise reduction. Control the traffic noise effect on the nearby urban areas. It can be also used to reduce the noise effect for factories and other sources.

Sound Barrier Structure: Sound barrier is mainly made up of steel column and sound absorption panel screen.The column is the main force of the sound barrier components. It is fixed on the rode or track anti-wall side of the embeded steel plate by bolts or welding. Absorption insulation board is a major component of the acoustic absorption. It is through high-strength spring clips to secure the tank in the H shaped column, formed the sound barrier. The sound barrier is about 1m-5m in height. The average noise reduction of the effective area covered by 10-15dB(A)(125Hz-4000Hz, 1-3 octave), up to 20 dB(A).Generally speaking, the higher the sound barrier, or farther away from the sound barrier, the better the noise reduction will be. 

Factors such as the distance between the frequency of sound barrier reduction , noise exposure and Noise Barrier height  and the source and the receiving point about. The relationship between the frequency components of the sound barrier great effect on noise reduction and noise, of more than 2000Hz high frequency acoustic noise reduction effect is better than the sound of an intermediate frequency 800-1000Hz around, but for the low frequency sound in about 25Hz. Due to the acoustic wavelength is relatively long and very easily from the diffraction barrier above the past, the effect of the poor. Usually, the sound barrier of high frequency sound can be reduced by 10-15dB. Sound barrier height, according to the distance between the source and receiving point design, barrier height increases one ties, the noise reduction capacity can be increased by 6dB, in order to make the barrier noise reduction effect is good, should try to make the barrier near the sound source or receiver point.
