The primary goal of this laboratory is to introduce students to the fundamentals of ultrasound measurements and to demonstrate the basic principles of ultrasound non-destructive testing technique. This laboratory presents the engineering principles of ultrasound measurements to the students by combining hands-on laboratory experience with just-in-time lectures. Specifically, the laboratory work consists of eight 3-hour sessions, where the students learn the engineering and physical principles behind the measurements of sound velocity in water and other materials, attenuation of ultrasound waves at different frequencies, directivity patterns of circular transducers with various resonance frequencies, and dimensions of the inhomogeneities in various materials. The work in the laboratory enhances the fundamentals taught in the classroom sessions. Another goal of this laboratory is to improve the students’ data gathering and communication skills. Therefore, a concise written report clearly describing all conclusions and comments is required within seven days after completion of the lab, upon which the students become familiar with basic acoustical instrumentation, have hands-on experience with ultrasonic and electronic equipment, and are able to demonstrate the basic principles of ultrasound imaging. In addition, the students are able to determine the frequency of the imaging pulse, pulse duration, pulse repetition frequency, cross section of the ultrasound beam, the axial distance between the transmitter and receiver/reflector, and the thickness of the material.


A new educational laboratory for ultrasound measurements (UM) and nondestructive testing (NDT) has been developed to serve primarily students pursuing a B.S. degree in applied engineering technology. The state of the art facility has also been designed to serve working
