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.
