Modelling of noise propagation in enclosures
Popis výsledku v původním jazyce
This paper provides a description of the computational approach for quick calculation of noise propagation in enclosed rooms. The main concern of these calculations is to determine the impact of provided modifications that reduce the negative aspects of increased noise levels in enclosed production areas. For this purpose, an algorithm was created based on the calculation of direct and scattered propagation of acoustic sound, which serves as the basis of the program on the LabVIEW platform and thanks to which the calculations were carried out in the production laboratory. The calculated values of the sound pressure levels for numerous variants of sound insulation adjustments were subsequently verified by measuring with a noise measuring device. The applied modifications reduced the sound pressure level at the operator's site by 7.1 dB (A).
