motorway sound barriers,
highway noise barrier
Highway Sound Barrier, sublway application, sky train application customized designs
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
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.
