This research will provide funding for participation by a team of experts from the U.S. in an international study of acoustically significant rooms in North America. Objectives of the research are: 1. The acoustical conditions in many significant rooms in North America will be characterized in detail by the new measures of acoustical quality. 2. Comparisons of the simultaneous measurements made by three research teams will test the acceptability of the draft of ISO 3382 standard for the new impulse response type of acoustical measurements regarding many specifics of the data acquisition and analysis process. 3. The comparisons of the different measurement techniques would also allow the extensive data base of detailed acoustical measurements for the statistical modeling of room acoustics with the architectural properties of the rooms on an unprecedented scale. These models based on an extremely large sample would provide a deeper understanding of the build-up and decay of sounds in complex rooms and the fundamental relationships among acoustical measurements and architectural properties of rooms. 4. High quality impulse responses from multiple source and receiver locations would be gathered in each room studied. The results of this research will have a major and immediate impact on the state of architectural acoustics. the scientific basis for acoustical decision-making in the design of buildings will be greatly expanded. The active participation of the acoustical consulting community (evidenced by their financial support of the project) would also allow for the rapid translation of the research results into everyday design practice.

这项研究将为来自美国的一组专家提供资金，参与一项关于北美声学重要房间的国际研究。本研究的目的是：1。北美许多重要房间的声学条件将通过新的声学质量测量来详细描述。2. 对三个研究小组同时进行的测量进行比较，将测试ISO 3382标准草案对新脉冲响应类型声学测量的可接受性，涉及数据采集和分析过程的许多细节。3. 通过对不同测量技术的比较，还可以建立广泛的详细声学测量数据库，以便以前所未有的规模对房间的建筑特性进行房间声学统计建模。这些基于极大样本的模型将提供对复杂房间中声音的积累和衰减的更深入的理解，以及声学测量和房间建筑特性之间的基本关系。4. 来自多个源和接收器位置的高质量脉冲响应将在每个房间收集研究。这项研究的结果将对建筑声学的现状产生重大而直接的影响。这将大大扩展建筑设计声学决策的科学依据。声学咨询团体的积极参与（由他们对项目的财政支持证明）也将允许将研究结果快速转化为日常设计实践。
