Three types of noise barriers, noise and noise reduction for your life!

声屏障常常使用在小区、工厂、公路、高架等隔音降噪的环境中，我们会发现声屏障的样式隔音设计总的可以分为三种，那就是折角、弧形、直立型声屏障，当然，还有就是三角锥型的声屏障，但是，在实际应用中很少，咱们就总体来分为三种，那么，这三种声屏障在隔音设计上有哪些优势呢？

Sound barriers are often used in noise and noise reduction environments, such as residential quarters, factories, highways, and elevated frames. We will find that the design of sound barrier design for sound barriers can be divided into three kinds, namely, angle, arc, erect sound barrier, and of course, a triangular cone type sound barrier, but in practical applications, we are rarely used. In general, it can be divided into three categories. Then, what advantages do these three kinds of noise barriers have in sound insulation design?

直立型声屏障

Erect sound barrier

首先是对直立型声屏障的介绍。一切声屏障的样式都是根据直立型声屏障而进行设计或改变。

The first is the introduction of the erect sound barrier. All types of sound barriers are designed or changed according to erect sound barriers.

直立声屏障在我国目前最常用的声屏障形状，一般都是直接放在地上，设置直立型声屏障抗风载能力强，不会轻易跌倒，从安装方面来说构造简单、 易于安装建造，不需要过于复杂的操作，这样会降低工程成本；还有日后的声屏障维修更换也是比较容易的。

At present, the vertical sound barrier is the most commonly used sound barrier shape in our country, which is usually placed directly on the ground. The erect sound barrier is strongly resistant to wind load and will not fall easily. From the installation aspect, the structure is simple, easy to install and built, and it does not need too complicated operation. This will reduce the cost of the project; there is also the sound of later sound. It is also easy to repair and replace the barrier.

直立型声屏障往往靠增加屏体高度，增加声屏障降噪效果；直立型声屏障常常用于工厂 厂房、小区等对于降噪要求不是特别高场所。

Erect sound barriers often increase the height of the screen and increase the effect of noise reduction; erect sound barriers are often used in factory buildings and residential areas for noise reduction requirements.

折角型声屏障

其次是对顶部折角声屏障的介绍。顶部折角声屏障是在直立型声屏障基础上进行隔音设计的。

The second is the introduction of the top bend sound barrier. The top corner noise barrier is designed for sound insulation on the basis of vertical sound barrier.

顶部折角型声屏障是在直立式声屏障基础上，把声屏障上部折向道路方向，折角小于45度，面向道路的一侧通常做成吸声表面。声屏障的支撑件多采用h型钢。这种声屏障可增加声程差，提高降噪效果，但用材有一定要求，施工技术高。为降低风荷载，使声屏障安全，一般大于5m的声屏障采用折角型声屏障。

The top bending sound barrier is based on a vertical sound barrier, which turns the upper part of the sound barrier to the direction of the road. The angle is less than 45 degrees, and one side of the road is usually made of a sound absorbing surface. H type steel is mostly used for the support of sound barrier. This kind of noise barrier can increase the sound path difference and improve the noise reduction effect, but the material has certain requirements and the construction technology is high. In order to reduce the wind load and make the sound barrier safe, the noise barrier generally larger than 5m adopts the folded angle type noise barrier.

弧形声屏障

Arc-shaped sound barrier

最后是对弧形声屏障的介绍。弧形式声屏障可以分为大弧形声屏障和小弧形声屏障， 它则结合了直立式声屏障和顶部折臂式声屏障的特点。不仅抗风载能力强，安装简捷，外形美观大方，而且降噪效果也很好，适用于各个场合及各种高度的声屏障。

The last is the introduction of the arc sound barrier. The arc form noise barrier can be divided into a large arc noise barrier and a small arc noise barrier, which combines the vertical sound barrier and the top folding arm type noise barrier. It not only has strong resistance to wind load, simple installation, beautiful appearance, but also has good noise reduction effect. It is suitable for various occasions and various high noise barriers.

顶部弧形声屏障结构设计的目的一般是使从屏障顶部绕射的衍射声得到有效衰减，弧形声屏障都是一次成型的，可以根据客户需要制定成型厚度可定制成：80mm 或者100mm。

The purpose of the structure design of the top arc sound barrier is generally to make the diffraction sound from the top of the barrier to be effectively attenuated. The arc sound barrier is all formed once, and can be made into 80mm or 100mm according to the needs of the customer.

样式虽是千变万化，但是声屏障的目的只有一个，那就是为大家营造一个安静的休息和工作的环境。

Although the style is ever-changing, the purpose of the sound barrier is only one, which is to create a quiet rest and work environment for everyone.
