Room Acoustics: Prediction

Room acoustics prediction, in general, is essentially the process where, using geometrical acoustics, octave-band echograms are predicted based on a 3D CAD model of a room. Frequency dependent material properties (absorption, scattering and transmission coefficients) are assigned to room surfaces and frequency dependent source directivities are assigned to sound sources. From this information echograms and impulse responses and a great number of numerical measures of e.g. speech intelligibility, and reverberation times can be estimated.
