The object of the research was to create a computer model of the Stanisław Moniuszko Grand Theater in Poznań. The scope of the study included changing the parameters of the ceiling over the orchestra pit, while not significantly changing the acoustic parameters of the entire interior. The study attempted to determine whether in the existing (or recently designed) hall, modifying the ceiling parameters could improve the sound quality for the audience. The main parameter was the specific weight of the ceiling. The influence of repositioning the inclined ceiling, its angle of inclination and size was also examined. The result of the conducted tests was unambiguous. The acoustic properties of the hall correlated with the weight of the ceiling acoustically connecting the orchestra with the audience. This is worth noting during the design stage of a concert hall.
