Communication Sciences Instructional Laboratories

该奖项为亚利桑那大学言语和听力科学系提供资金，用于购买现代换能器系统和两个MacIntosh工作站，以创建虚拟仪器，支持通信科学的三门实验室课程。这些课程是：SP H 260-言语科学、SP H 280听觉科学和SP H 461语音科学仪器。换能器系统包括(A)气动测速仪、(B)电声门仪和(C)磁力计。一个额外的换能器系统将支持产生高质量的声音刺激，用于实验室的听觉感知练习。核心仪器计算机工作站将配置适当的模拟到数字和数字到模拟的硬件，使学生能够获得语音的频谱分析、基频等值线和声压级测量，以及气压/流量、电声门图和磁力计输出和电生理信号的永久书面记录。听力科学实验室将采用适应性心理物理方案中的仪器，使学生能够使用现代方法调查听觉感知。虚拟仪器和传感器将取代老化、无支持、不适应现代基于计算机的数据收集和分析方法的专用仪器。受赠人正在将该奖项与非联邦来源相匹配。

This award provides funds to the Department of Speech and Hearing Sciences at the University of Arizona to acquire modern transducer systems and two MacIntosh workstations to create virtual instruments to support three laboratory courses in communication sciences. The courses are SP H 260 - Speech Science, SP H 280 - Hearing Science, and SP H 461 Instrumentation in Speech Science. The transducer systems include (a) pneumotachographs, (b) an electroglottograph, and (c) magnetometers. An additional transducer system will support the generation of high quality acoustical stimuli for laboratory exercises in auditory perception. The core instrumentation, the computer workstations, will be configured with appropriate analog to digital and digital to analog hardware to enable the students to obtain spectral analyses, fundamental frequency contours, and sound pressure level measurements of speech, and permanent written records of air pressure/flow, electroglottograph and magnetometer outputs, and electrophysiological signals. The Hearing Science laboratories will employ the instrumentation in adaptive psychophysical protocols to enable the students to investigate auditory perception using modern methods. The virtual instruments and transducers will replace dedicated apparatus that is aging, unsupported, and unadaptable to modern, computer-based data collection and analysis methods. The grantee is matching this award with non-Federal sources.
