The differing heights of protrusions on the CityScape profile were inspired by the Johannesburg city skyline and serve to spread sonic energy out in the time domain. Each protrusion absorbs a slightly different slice of the frequency spectrum. This is why a room treated with CityScape panels will retain a bit more “feel” than a room that is treated with a stronger absorber like Wedge foam or Pyramid foam panels and why, when coupled with a sufficient amount of Diffusion tiles will result in a well-controlled, natural-sounding space.
