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.

本研究的目的是开发一种方法， 建筑师和他们的顾问预测声学质量 在设计过程中，以经济和及时的方式 方式 美国国家科学基金会早期的一项研究结果显示， 启动补助金表明，超声波缩放脉冲 在小规模研究模型中进行的响应测试具有潜力 为设计者提供广泛的声学信息。 该研究有4个主要组成部分： 1. 将进行一系列广泛的声学测量， 聚集在许多类型的现有建筑物中， 声学质量，作为设计数据库。 2. 在建筑物内进行的客观测量将 与声学的主观评估有关， 建筑物的质量，以确定哪些 测量值可用作声学设计标准。 3. 第1项中所研究建筑物的声学模型。上述 将进行测试，以进一步了解哪些标准提供 建模过程中最有用的设计信息。 4. 多通道数据采集与数字分析系统 建筑声学研究仪器 空间（阿里亚斯））将被开发， 声学分析在多个地点占用或 无人居住的建筑物和声学模型， 比例为1：10至1：100。
