Sound dissipation panel v2

Another version of the panel (see the previous one in my profile) imitates the classic sound pyromidal panel for sound dispersion. It differs from the previous version in that it has pyramids of different heights, and accordingly its edges are located at a different angle. It is believed that this configuration scatters sound waves of different lengths better. Effectively disperses sound in a room, preventing unwanted echoes. Looks aesthetically attractive. The size of one panel is 240 by 240 millimeters; by changing the filling from 0% to 100% you can change the sound absorption of the panel. But first of all, such panels are designed to reduce parasitic echo from the walls, and not to muffle sound.
