Abstrakt: A method for studying the correlation between the acoustic features and the articulation or intelligibility score of an auditorium has been developed. An artificial speaker is placed in the speaker position. Nonsense monosyllables are reproduced via this speaker. In different listener positions, stereophonic recordings are made via an artificial head with microphones in the ears. These recordings are later reproduced via earphones to a test group. The method enables the listening conditions to be kept equal, and only the acoustic character of the room will influence the results. Pilot studies have been made under laboratory conditions and have shown that the method is sensitive and reveals effectively the acoustic features of a room. These studies have been made, and certain introductory data are given. This method will be applied in different auditoriums and also tested under laboratory conditions to study the optimal value of reverberation time, definition (after Meyer), etc. [ABSTRACT FROM AUTHOR]
