Abstract: A key objective of the present contribution is to emulate the paucity of detailed input data at the outset of a room acoustics simulation process. To this end, four existing multi-purpose performance halls were selected and respective acoustic models were generated. Thereby, in the absence of certified material data, the relevant input information was based on the available qualitative architectural documentation. Reverberation time and sound level distribution were measured and independently simulated using a room acoustics modelling tool. The comparison of the measurement results with the initial as well as modified simulation results contribute to the exploration of acoustic simulation tools' reliability.
