Room Acoustics: Prediction
Room acoustics
prediction, in general, is 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 coefficints) are assigned to
room surfaces and
frequency dependent source
directivities are assigned to sound sources. From this information
echograms
and a great number of numerical measures of e.g. speech
intelligibility,
and reverberation time can be estimated. It is also possible to
post-process
the echograms and create room imulse responses for Auralization.
