noise barrier panel - JB-L12

Sound Barrier Panel ---- noise barrier panel

Definition: Sound waved during the process of transmission, meets the sound barrier occurs when the reflection, transmission and diffraction three kind of phenomenon.

Classify:1. Sound barrier according to the material classification and can be divided into the following categories: metal sound barrier(metal shutter, metal screen hole), concrete sound barrier (lightweight concrete, high strength concrete), PC sound barrier, FRP acoustic barrier, etc.

2.According to the different uses and can be classified into such categories: railway noise barriers , highway sound barrier, urban landscape sound barrier, residential area drop noise barrier,etc.

Structure : Sound barrier is mainly composed of steel structure column and suction acoustic screen plate of two parts, the pillar of the noise barrier is the main stress components, it through the bolt or welding fixed in road anti knock at the door or track side of the embedded steel plate; Suction noise barrier is the main acoustic acoustic components, it through the high strength spring clamp should be fixed to the H type column slot, form the sound barrier.

Sound barrier height in 1m between 5m, covering effective regional average noise reduction for 10---15db(125hz--40000hz ,a third octave),the highest 20db. Generally speaking, the higher the sound barrier ,or from the sound barrier more far,the noise reduction result is better.

Type1: Plane type piercing sound barrier

Plane punch sound barrier of the surface of many holes, the voice into holes, will be in the inner structure of the wild reflex, until most of the acoustic energy consumes, into heat energy, to the effect of sound insulation.

Type2:Combination transparent type sound barrier

Combination transparent acoustic barrier has 5 + 5 toughened glass or PC sunshine plate and PC endurance plate, can according to your drawings needs custom.

Type3: Shutter hole sound barrier

Shutter hole sound barrier specification: conventional 1960 * 500 * 100 , 2460 * 500 * 100 can according to the customer request custom size;

Material: galvanized sheet, aluminum

Type4 : Top arc sound barrier

material: galvanized aluminium plate

Forming thickness can be fixed made: 80 mm or 100 mm

Type5:Bump punch sound barrier

Metal plate thickness: 0.6 mm and 0.7 mm and 0.8 mm and 1.0 mm (can according to the customer request custom make)

Forming thickness: 80 cm, 100 cm, etc. (can according to the customer request custom make)

Pass: round hole

Type6: Big arc sound barrier

Acoustic system quantity: maximum absorption coefficient of 0.95.

Type7: Top Angle sound barrier

Top Angle sound barrier material: galvanized aluminium plate

Angle: 45 degrees

Forming thickness can be fixed made: 80 mm or 100 mm
