This study presents the development and validation of a new software that enables quick, reliable, and simultaneous measurement of reverberation time T60 in multichannel systems. The software's design allows for the easy adjustment of reverberation time measurement parameters, shortening the overall time required for determining sample absorption coefficients. Determining these coefficients is based on the measured reverberation times. Compared to the traditional method, the use of this new software allows for a greater number of measurements to be conducted within the same time period, thus enhancing the credibility of the measured acoustic material properties of the samples. The software accelerates the execution of reverberation time measurements to a degree that allows for the qualitative determination of reverberation time measurement parameters, which until now were based on the subjective experiences of experts. The study's results indicate the software's significant potential for improving the efficiency of sound absorption coefficient measurements on samples sized between 0.36 m2 and 0.64 m2, facilitating its use in the development of new acoustic materials.
