PURPOSE: A non-equilibrium cutoff wall structure of the indoor for even sound diffusion is provided to reduce the distortion caused by sound absorption of a sound absorbing material by inducing even sound diffusion and blocking transmission of sound noise. CONSTITUTION: A non-equilibrium cutoff wall structure of the indoor for even sound diffusion comprises a wall main body (40), a stud (20), and a soundproof panel (10). The wall main body forms an indoor wall structure of a rectangular plane or a square plane. A stud is fixed to a bottom surface, a ceiling, or the wall main body, and the soundproof panel is fixed. The soundproof panel is installed on one side wall in order to be parallel to a plane, and is installed in order to be inclined on the other side wall so that the walls facing each other are installed in order not to be parallel.
