Sound dissipation panel

A panel imitating a classic sound pyromidal panel for sound dispersion. 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.
