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.

该奖项为亚利桑那大学言语和听力科学系提供资金，用于购买现代传感器系统和两个 MacIntosh 工作站，以创建虚拟仪器来支持通信科学的三门实验室课程。 这些课程包括 SP H 260 - 言语科学、SP H 280 - 听力科学和 SP H 461 言语科学仪器。 换能器系统包括（a）呼吸速度描记器、（b）电声门描记器和（c）磁力计。 额外的换能器系统将支持生成高质量的声刺激，用于听觉感知的实验室练习。 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硬件，使学生能够获得频谱分析、基频轮廓和语音声压级测量，以及气压/流量、电声门图和磁力计输出以及电生理信号的永久书面记录。 听力科学实验室将采用自适应心理物理协议中的仪器，使学生能够使用现代方法研究听觉感知。 虚拟仪器和传感器将取代老化、不受支持且不适应现代基于计算机的数据收集和分析方法的专用设备。 受资助者将该奖项与非联邦来源相匹配。
