It can happen if large flat reflectors and nearby walls are not treated with absorbers or diffusers. 8 Measured temporal and frequency response of the total field, consisting of the direct and reflected sound. The top case is for specular reflection, the bottom case is for diffuse reflection (after D’Antonio and Cox1). 9 Cylindrical wave reflected from a hybrid surface using an FDTD model; the shaded wells are filled with absorbent. Applications and basic principles of diffusers 39 the comb filtering is removed and the variation in levels reduced.

8 Mineral wool in a partition. 9 Geometry for transfer matrix modelling of a multi-layer absorbent. absorbent to be calculated. For instance, it enables the case of a rigidly backed porous absorbent to be considered. This is the most important acoustic case, because it represents an absorbent placed on a wall, floor or ceiling. 9. It is assumed that only plane waves exist within the layers. It is further assumed that the propagation is entirely contained in the x-y plane. By considering the continuity of pressure and velocity at the boundaries, it is possible to relate the surface pressure of one layer to the next.
