The combination of lights and sound insulation panels is an innovative integrated design of acoustics and lighting, enhancing both the practicality and aesthetics of a space through functional fusion.
Structural Design: Elevated bridge sound barriers often combine a top-mounted curved steel plate with LED strips. For example, a 150mm diameter cylindrical light cover is embedded between the bridge supports, paired with an acrylic transparent window and a sacrificial screen below, achieving both noise reduction and lighting functions.
Sound and Light Synergy Technology: Some commercial spaces use translucent concrete sound-absorbing panels with built-in LED strips that are linked to the lighting via sound pressure sensors. When ambient noise exceeds a threshold, the strips automatically switch to a breathing mode, converting sound energy into visual feedback.
Transportation Sector: In elevated bridge projects in Jiangsu and Shaanxi, lighting is integrated into the top of the sound barriers, reducing traffic noise and providing nighttime road illumination.
Commercial Spaces: Bars, retail stores, and other venues enhance the user experience through interactive sound and light interfaces (such as temperature-sensitive color-changing sound-absorbing panels) while controlling noise propagation.
Industry and Construction: Composite damping sound barriers can be combined with lighting equipment for use in factory workshops or residential walls, addressing both sound insulation and functional lighting needs.
