AI Technical Summary

Technical Problem

The traditional sound barrier is a single-layer structure, with poor noise reduction effect, unable to effectively control reflected and refracted sound waves, and poor connection firmness in humid environments, affecting aesthetics and stability.

Method used

The scattered superposition wave acoustic barrier design is adopted, and the misaligned superposition of two layers of wavy screen components increases the complexity of the sound wave path, and the wavy sound absorbing bar and reinforced base plate are used to improve the sound absorption performance. At the same time, the card slot and card block structure is used to achieve rapid assembly and stable connection.

Benefits of technology

It improves the noise reflection, diffraction and absorption capabilities of the acoustic barrier, enhances the overall noise reduction effect, and improves the aesthetics through dynamic light and shadow effects, while improving the stability and corrosion resistance of the structure.

Abstract

The utility model relates to a staggered and superposed wave-shaped sound barrier which comprises a base and a frame. The base is fixedly connected with the frame, and the plate body, the first wave-shaped screen body assembly and the second wave-shaped screen body assembly are sequentially installed on the inner side of the frame from front to back. Wherein the first wave-shaped screen body assembly and the second wave-shaped screen body assembly are similar in structure, each wave-shaped screen body assembly is composed of a plurality of wave-shaped sound absorption strips, and the left side face and the right side face of each wave-shaped sound absorption strip are both wave faces; the wave-shaped sound-absorbing strips in the first wave-shaped screen body assembly and the wave-shaped sound-absorbing strips in the second wave-shaped screen body assembly are arranged in a staggered manner, are overlapped with each other and then are fixedly connected with the plate body; and a wave-shaped sound barrier is formed. According to the wave-shaped sound barrier, the two layers of wave-shaped screen body structures are overlapped in a staggered mode, so that the path of sound waves is more complex when the sound waves pass through the sound barrier, the reflection, diffraction and absorption capacities of the screen bodies on noise are improved, noise energy is effectively weakened, meanwhile, the sound barrier can present rich light and shadow effects and dynamic aesthetic feeling along with changes of light rays and observation angles, and the sound barrier is more attractive. And the appearance is more attractive.
