A comparative analysis between different sets of absorption coefficients, found or calculated from a variety of sources and methods, including traditional databases and newer in-situ methods, was carried out. This analysis utilized different architectural acoustic simulation software packages for verification of results and further comparison. Initially, a shoebox model was compared for reference and brief comparison between the software packages was made. Then, the main analysis was conducted using the model of the RWTH Aachen Institute of Technical Acoustics’ Seminar Room. This room was simulated with all the different sets of absorption coefficients through both simulation software packages. The purpose of this analysis was to provide a reference for the variation of room acoustic parameters from the different sources of absorption coefficients.
