Metal Curve Highway Noise Reduction Barriers Good Sound Absorbing Property

The feature of noise barrier

1. Good sound insulation
 

Noise reduction mechanism of acoustic panel is reflected rather than absorbed. After

testing,15 and 20 mm acrylic sheet,respectively 32 and 35 db noise reduction.If the top

of the acoustic panel made inwardly curved shape, sound effects will be better.

2. Excellent weather resistance
 

Acoustic panels in a variety of applications shows excellent weather resistance for

outdoor use warranty of 25 years;while others such as PC sheets, turn yellow in several

years only,on the visual environment have been affected.

3. High transparency
 

High transmittance over 91% (transparent plate), even higher than glass.The initial

transmittance is better than other transparent plastics,and with surface damage,the

transmittance will be further reduced for other transparent plastics such as PC sheet;
 

4. Processing is simple
 

Compared with glass,Acrylic sheet is more safer and easier to cutt and transport on

site.In addition,acrylic acoustic panel can be cold bend also be thermoformed,modeling

and diverse;

5. Strongimpact resistance
 

Acrylic acoustic panel has excellent impact resistance; while the glass is very easy to

be broken and will be completely destroyed by the impact

6. Light weight
 

Lighter than glass(specific gravity of about 50% of the glass), common support

structure can be used,also more secure,convenient for installation.
 

7. Protection of Birds
 

Acrylic reinforced sheet with embedded polyamide threads making it easier for birds

identify in order to avoid bruises on the highway.
