1.Material characteristics: Why choose reinforced acrylic?

The reinforced acrylic sound insulation barrier is made by combining modified acrylic sheets with internal reinforcing ribs.It combines the stability of traditional materials with the advantages of new materials.Compared with traditional metal barriers, it weighs only one third of the metal, but its impact resistance has been enhanced by 50%.Moreover, its light transmittance is over 92%, and it will not obstruct the landscape like concrete barriers.The outdoor environment is inevitably dusty and rainy. Just wipe it with a damp cloth and it will be clean.

2. Structural design:

The main body of the barrier adopts a structure of “acrylic sheet + honeycomb reinforced ribs”.After the sound wave hits the acrylic board, it reflects and attenuates multiple times through the internal honeycomb cavity.At the same time, the ribs disperse the energy and prevent resonance.According to the monitoring of Jiaxing Municipal Engineering Research Institute, its sound absorption coefficient can reach 0.85, which can effectively block mid to high frequency noise of 800-5000Hz.

3. Construction Key Points:

Construction requires three steps:The on-site survey determined the height of the barrier (usually 2.5 – 3 meters).Factory prefabricated reinforced acrylic sheet.During the hoisting process, ensure that the deviation between the plates is no more than 1mm to avoid sound leakage.

After installation, a 24-hour sound wave tracking test is required to ensure that the noise reduction effect meets the standard.

4. Noise Reduction Effect:

Taking a certain road section as an example, the noise level during the morning and evening rush hour before installation reached 70-75 dB.After installing the Reinforced Acrylic Sound Barrier, the noise levels in the surrounding residential areas dropped to 50-55 dB.
