| Summary: | The most important problem of room acoustics is the
evaluation of the acoustic quality of projected and modernized rooms. To this
end it is necessary to work out a calculating impulse response algorithm for a
digital room model. The virtual rooms impulse response manners of modeling are
described in the article. The impulse response synthetic models have been
evaluated on the basis of selected numerical factors and a simple auditory test.
Thanks to the impulse response calculation it is possible to evaluate the
subjective and objective room acoustic properties and hence to run the room
simulation tests (the sound sources configuration, the room planning) in order
to reach optimal solutions, which meet a given criterion. The problems described
are related to the ''virtual sound space'' concept. Intuitively, we mean by this
a sound reality model, which enables, on the basis of the model and measurement
data, an audio impressions simulation of the existing and being under projection
acoustic systems. A basic process, which enables the sound reception, is the
test signal and the impulse response convolution. |
