locomotive power system, wheel rail vibration caused by wheel, and vehicle body disturb air while moving.
The range of noise frequency
the major noise source is wheel rail rolling, frequency is from 200HZ to 4000HZ.
Design standard
HJT90-2004 Acoustic design of sound barrier and measurement standards
TBT3122-2010 Test method for acoustic elements of railway’s sound barrier
GB50157-2013 Subway design standard
Main technical requirement
Panel material can bear the load of 1500N/m2, deflection is less than 1mm;
Breaking load should be greater 200N.
Panels should have good anti-corrosion, waterproof and damp-proof, and weather resistance.
When the speed below 60km/h, the sound absorption coefficient can not less than 0.6, generally is greater than 0.75.
Noise barrier types
Our company can manufacture and provide many types of sound barrier, such as metal, non-metal, folding, vertical, curve, transparent, blind holes,etc. It mainly used in the roads, highways, overhead complex roads and other noise sources to achieve sound insulation and noise reduction. Aluminum foam noise barrier has the advantages of fireproofing, weather and corrosion resistance, good sound absorbing property. It has been applied in domestic and overseas engineering projects.
