Evaluating Accoustical Qualities of Buildings using Small- Size Models

本研究的目的是开发一种方法，使建筑师和他们的顾问能够在设计过程中以经济和及时的方式预测建筑物的声学质量。美国国家科学基金会（NSF）早期的一项研究启动拨款的结果表明，在小型研究模型中进行的脉冲响应测试的超声波缩放有可能为设计人员提供广泛的声学信息。本研究主要包括4个部分：1。一系列广泛的声学测量将在许多类型的现有建筑中收集，这些建筑具有不同的声学质量，作为设计数据库。2. 在建筑物中进行的客观测量将与听众对建筑物声学质量的主观评估有关，以确定哪些措施可以作为声学设计标准。3. 第1项建筑物声学模型研究。以上将进行测试，以进一步了解哪些标准在建模过程中提供最有用的设计信息。4. 将开发一个多通道数据采集和数字分析系统（建筑空间声学研究仪器（ARIAS）），以便在占用或未占用建筑物的多个位置进行详细的声学分析，并在1:10到1:10的比例范围内进行声学模型。

The objective of this research is to develop a method to enable architects and their consultants to predict the acoustical qualities of buildings during the design process in an economical and timely manner. The results of an earlier NSF Research Initiation grant have shown that ultrasonic scaling of impulse response tests made in small-size study models has the potential to provide a wide range of acoustical information to designers. There are 4 main components to the research: 1. An extensive series of acoustical measurements will be gathered in many types of existing buildings with varying acoustical qualities to serve as a design data base. 2. The objective measurements made in the buildings will be related to the subjective assessment of the acoustical quality of the buildings by listeners to determine which measures are useful as acoustical design criteria. 3. Acoustical models of the buildings studies in item 1. above will be tested to further understand which criteria provide the most useful design information in the modeling process. 4. A multichannel data acquisition and digital analysis system (Acoustical Research Instrumentation for Architectural Spaces (ARIAS)) will be developed to enable detailed acoustical analysis at multiple locations in occupied or unoccupied buildings and in acoustical models ranging in scale from 1:10 to 1:100 to be performed.
