Zusammenfassung:Computer simulation results for the absorption capacity of a semi-infinite noise screen with the absorbing layer are presented. The screen efficiency was determined depending on the location of the sound source and the sound frequency. The influence of the size of the absorbing layer on the noise screen’s efficiency is analyzed. It is shown that there is an optimal size of the absorbing layer for which the absorption of the screen will be maximum. The article was prepared based on materials in a report at the Third All-Russian Acoustics Conference (September 21–25, 2020, St. Petersburg).
