abstract = "The frequency range of a Schroeder sound diffuser is determined by its dimensions, depth of the wells and total width. Several authors have studied the relationship between the diffuser dimensions and the lowest and highest frequency with significative diffusion. In this paper we have
verified the validity of previous works. Furthermore, we have extended the working frequency range to lower frequencies by means of a multiobjective optimization. Preliminary results reveal that the frequency range can be extended to lower frequencies, particularly if different widths are
defined for each well.",
