Abstract
The article presents a room acoustics study conducted for a multi-purpose hall, which is currently in the design phase. The hall is part of the Cultural Center building, which will be constructed in Zagórz, a small town located in the southern part of Poland in the Podkarpacie region. The architectural design was developed by Studio Święciński Architekci, based in Krosno. The results of the acoustic prediction for the hall were obtained using the open-source software I-SIMPA. To perform the acoustic study, the multi-purpose hall was geometrically modeled as a 3D shape in acoustical scale; sound absorption and scattering coefficients for the internal surfaces were then assigned along with the sound source and receivers in the audience area. Several acoustic parameters (T_Sabine, T_Eyring, T30, EDT, C80, D50, G, STI) were calculated in pre and post-treatment conditions, to simulate the acoustic efficiency of the conference hall in accordance with its future use.
