由于混响时间作为音质预测指标的不足已被认识到，许多新的措施被提出。其中，早晚音比和耳间互相关被普遍认为是音质的两个主要方面的相关性。因此，目前的工作包括在200至2500个座位的大厅内对这些数量进行大量测量。这项工作的目的是提高对较新的衡量标准的熟悉程度，提供更多已公布的数据，并探讨这些衡量标准对其他数量的依赖性。新措施的变化在大厅内和大厅之间进行了审查。在混响时间方面明显相似的大厅，当考虑到早到晚的声音比率时，显示出明显的差异。
As the inadequacy of reverberation time as a predictor of the acoustical quality of auditoria has been recognized, many new measures have been proposed. Of these, early‐to‐late sound ratios and interaural cross correlations are generally accepted as correlates of two major aspects of acoustical quality. Accordingly, the present work includes a large number of measurements of these quantities in halls ranging from 200 to 2500 seats. The purpose of the work was to improve familiarity with the newer measures, to provide more published data, and to explore the dependence of these measures on other quantities. Variations of the new measures were examined within and among halls. Halls that are apparently similar in terms of reverberation times showed clearly identifiable differences when early‐to‐late sound ratios were considered.
