ABOUT THE DIFFERENT TYPES OF TEST SIGNALS DURING ACOUSTIC MEASUREMENTS IN THE SPECTACULAR HALLS
The results of experimental studies of the possibility of using different types of test signals for determining acoustic parameters of rooms are presented in this paper. The measurements were performed in the new organ hall of "Rodina" in Chelyabinsk. They were held in an empty room, and when it was filled by the audience. It was found that in addition to commonly used pseudo-random sequences of maximum length and pistol shots to determine the reverberation time the abruptly ends organ chords can be used. The work was also found good agreement between the values of the reverberation time of the hall with the audience measured in the ready room and calculated on a computer model in the acoustic design.
