description: The theme of the final qualification work: "Assessment of the acoustic properties of multipurpose halls."
This article is devoted to assessing the convergence of the results of calculating the acoustic parameters of multi-purpose halls after they are processed by acoustic materials with the measurement results and identifying factors that affect the convergence of the results. Tasks that were solved during the study:
1. Analysis of existing theories of sound propagation in a room (wave, static and geometric) used in assessing the acoustic quality of a room;
2. Determination of the main and additional acoustic indicators of multi-purpose halls by the method of mathematical modeling in the EASE program and analytically using the methods adopted in the Russian Federation;
3. Compare the indicators obtained as a result of the calculation with the results of measurements of multi-purpose halls.
4. Identify factors that influenced the convergence of the results.
This paper sets out the criteria for evaluating the acoustic parameters of a room based on three theories of acoustics. The permissibility of their use is given. Analytical calculation of the acoustic criteria of three multi-purpose halls and modeling of acoustic processes in these rooms using the EASE 4.3 software package was carried out. Field measurements were carried out in three rooms in order to assess the convergence of analytical and experimental methods.
As a result of the analysis of the calculated and measured indicators of the acoustics of the hall, a partial correspondence was found between the results of measuring the reverberation time and the calculation using the Arau formula. Based on the differences obtained, factors were formed that are able to influence the convergence of the results.
