Piercing-pressure absorbing panels mainly in the bottom surface of a metal plate of clouds many recessed triangular pyramid having a conical bottom elliptical micropores, but also on the top surface of the metal plate member is provided with a fine wave-shaped surface, and in the wave corresponding to the type of surface fine oval holes around the top of the recessed also forming a triangular pyramid; accordingly, the reflected sound waves collide with each other to produce interference attenuation, while even if some sound waves penetrate the pores oval cones cone bottom, also cause acoustic transmission loss, to achieve better and faster absorbing effect group setting. The perfect combination of modernist architectural concept has a "green, durable, beautiful, absorbing strong, good sound effects, easy to install," and so on.
