TRANSPARENT NOISE KEEPING PANEL THAT CAN ABSORB AND INTERFERE NOISE

摘要

A transparent sound proof panel that can absorb and interfere with noise is provided to improve its sound absorbing performance by installing sound ribs, which is bent, in hollow pipe to guide noise from the outside through the ribs. A transparent sound proof panel that can absorb and interfere with noise comprises an upper frame(1), a lower frame(2), and two lateral frames(3). Each frame includes a sound rib, a sound passage, a panel insertion groove, a protrusion, and a hollow pipe. The hollow pipe, whose one part is opened toward a sound source, extends longitudinally. The sound rib is attached to one end of the hollow pipe inside the hollow pipe. The sound passage is formed by the sound rib. The panel insertion groove is formed on the outer bottom surface of the hollow pipe and formed into a reversed 'U' shape.
