Abstract
Regarding scattering coefficient that represents acoustic scattering of wall surfaces, a reverberation room method for measuring the random-incidence value has recently standardized by ISO 17497-1. The scattering coefficient is widely used in geometric room acoustic simulation, however, there are few measured data available. In this report, a variety of rib and block structure walls are tested by the reverberation room method in order to provide a database of scattering coefficients. Furthermore, characteristics of the scattering coefficients are investigated, especially regarding the effect of surface profile and absorbent finish for rib structures, and that of arrangement for block structures.
