International Study of Acoustically Significant Rooms in North America

这项研究将为来自美国的一个专家小组参与一项关于北美声学意义重大的房间的国际研究提供资金。本研究的目标是：1.北美许多重要房间的声学条件将通过新的声学质量指标来详细描述。2.对三个研究小组同时进行的测量进行比较，将测试关于数据采集和分析过程的许多细节的新的脉冲响应型声学测量的ISO 3382标准草案的可接受性。3.不同测量技术的比较还将使详细的声学测量的广泛数据库得以建立，以便以前所未有的规模对房间声学和房间的建筑特性进行统计建模。这些基于极大样本的模型将提供对复杂房间中声音的建立和衰减以及房间声学测量和建筑属性之间的基本关系的更深层次的理解。4.在所研究的每个房间中收集来自多个源和接收器位置的高质量脉冲响应。这项研究的结果将对建筑声学的状态产生重大而直接的影响。建筑设计声学决策的科学依据将得到极大拓展。声学咨询界的积极参与(证明是他们对该项目的财政支持)也将使研究成果迅速转化为日常设计实践。

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.
