Acoustic walls are composed of complex modular acoustic panels side by side on an appropriate construction.
The panels are acoustic structures designed to block the passage of noise.
The wall will typically face the noise source side with a perforated metal sheet that is housing a noise absorbing material.
Walls are provided with various insulation capabilities and vary in shape and size.
Acoustic walls made by HNA are manufactured from galvanized steel and are painted with a UV-resistant paint to improve external durability.
