Abstract: The extension of the frequency and volume ranges in recording and reproducing sound has aroused a greater and more critical consciousness of the importance of theater acoustics. It follows that higher fidelity in reproduction excites greater intolerance of the needless distortion caused by poor acoustics of the theater. To cope with the new situation, engineers have developed new instruments for acoustical analysis, which provide greater precision and facility in detecting defects and in determining the necessary corrections. In addition to instrumental developments there have been concurrent advances in acoustical theory and practice. The result is that the more stringent requirements imposed on the acoustics of the theater by the enlarged frequency and volume ranges can be fulfilled adequately and practically. The paper discusses the requirements and describes some of the available methods for complying with them.
