CERATMOS is a half-spherical tridimensional diffusor especially dedicated to Audio Dolby Atmos control rooms. There are two versions of this model: half-spherical and spherical. The half-spherical is to be set on the surfaces of walls or ceilings whereas the Spherical is meant to hang from the ceiling. This device was designed to enhance the acoustic quality of a multi-source control room, like Dolby Atmos. It consists of a half-spherical shape with intricate surface patterns that evenly scatter sound waves in all directions. This diffusion process helps to minimize flutter echoes and standing waves, modal resonances and hot spots, by breaking up direct reflections and redirecting sound energy, thus promoting a more balanced and natural sound field. CERATMOS  leads to an improved sound division of each channel source clarity, definition, and spaciousness of audio. A reflected sound field from a convex spherical surface is unquestionably better than concave surfaces that cause several interferences. Jocavi has developed this model from the shape of a sphere, slightly ovalized to better adapt the scattering coefficient angles to the scale and size of control rooms. We adapted and segmented the curved shape of a sphere into small and flat elements, replacing the convex curved surface by small flat plans such as rectangles, trapezoids, and triangles, thus emphasizing and consequently better controlling the scattering factor. This segmentation positively influences the accuracy calculation of the focal point of incidence, i.e., of the sweet spot. This half-spherical diffuser has a wide scattering diffusion coefficient according to Dolby Atmos rooms’ characteristics. Its depth results in a focused effect taking multi-source surround sound systems into account. CERATMOS is consequently a secondary source that will radiate acoustic pressure to the receptor position, allowing it to form a larger hearing warhead in the position of the receptor (sweet spot), perfectly integrated with the several sound speaker sources. These strategically well positioned diffusers contribute to better distinguish the sound of each channel where accurate sound reproduction is crucial.
