ABSTRACT: Process equipment placing in industrial
premises leads to essential change of room acoustic characteristics: mean
length of sound rays’ free runs, reverberation time and mean absorption factor
in a room. The changes influence distribution of the reflected sound energy in
premise volume. Failure to take account of the given circumstance results in
errors at definition of sound pressure levels and an estimation of efficiency
of building-acoustic measures of noise abatement. In the paper the results of
computer modeling of acoustic processes in premises with the process equipment
are considered and influence of the equipment on a sound absorption indoors is
analyzed. The computer simulation is carried out on the basis of the ray
tracing method with taking into account rays’ energy distribution in a room. It
is shown that such approach allows determining objectively the integral
acoustic characteristics of industrial premises, takes into account influencing
to them the room parameters, the presence and scattering characteristics of the
equipment and makes more accurate the equations putting into engineering
practice.
