Spiral Noise Barrier / Noise Barrier

The concept is to apply “Quarter-Wavelength Theory” and nature’s “Spiral Shape” to achieve sound insulation. The sound is absorbed by guiding sound waves into the tapered quarter-wave pipe, and produce resonance to transform sound energy into thermal energy. The “Spiral Noise Barrier” isolated sound through its shape instead of material, which broadens its choice in material use and its state of application. It is designed to isolate sound pollution of common road conditions with eco-friendly notion, and is economical to produce, lightweight to transport, easy to assemble and perform with sustainability regardless of the weather condition.
