In this paper a new approach to design sound phase diffusers is presented. The acoustic properties of such diffusers are usually increased by using single objective optimization methods. Here we propose the use of a multi- ...

El presente trabajo trata el estudio de la difusión y los parámetros acústicos, en una pequeña sala usando la técnica de simulación de Diferencias Finitas en el Dominio Temporal. El estudio se realiza en 3 condiciones ...

Sonic crystals have been demonstrated to be good candidates to substitute for conventional diffusers in order to overcome the need for extremely thick structures when low frequencies have to be scattered, however, their ...

A sound diffuser is proposed based on sonic crystals, structures formed by a periodic distribution of cylindrical scatterers in a host medium, which is usually air. The diffuser is a so-called biperiodic structure, as ...
