The authors argue that irregular geometrical patterns of industrial premises and items of the
process machinery installed in industrial premises cause redistribution of the acoustic energy and
its essential acoustic properties, including the average free path length, the reverberation time, and
the average sound absorption coefficient. Any failure to take account of the above influence causes
errors in identification of the sound pressure intensity and in assessment of efficiency of design and
acoustics-related actions aimed at noise reduction that incorporate sound-proof facing.
The authors present the results of simulation of acoustic processes in the premises that have
items of process machinery installed, and analyze their influence on the sound absorption intensity.
The software developed on the basis of the beam tracing method is designated to assess the influence
of patterns of arrangement of items of equipment onto acoustic parameters of premises. The
software comprises independent modules designated for the simulation of acoustic processes in
different premises that demonstrate different acoustic properties. The results of the research demonstrate
that the software simulation of noise processes on the basis of the method of beam tracing
is an effective tool that may be effectively applied in the analysis of noise patterns inside industrial
premises. The software may be employed to identify integrated acoustic patterns inside industrial
premises with account for the influence of dimensions of premises, characteristics of items of process
machinery capable of disseminating sounds, etc. and other factors of signifi cance in terms of
the distribution of reflected sound energy. Presently, advanced software is being developed on the
basis of the proposed method of noise assessment in the premises that have irregular geometrical
patterns.
