Abstract

In this paper a method to control acoustic properties in a room with topology optimization is presented. It is shown how the squared sound pressure amplitude in a certain part of a room can be minimized by distribution of material in a design domain along the ceiling in 2D and 3D. Nice 0-1 designs can be obtained when optimizing for low frequencies, but for higher frequencies the method results in complicated designs with porous material.
