During nondestructive evaluation (NDE) of a material, an NDE instrument typically is used to receive the inspection signals and display them for visual interpretation. Work has been underway to convert these signals to a range of aural (audible) signals with the intent to enhance the accuracy of evaluation through the use of two senses (ears and eyes) instead of one. This paper describes auralization of ultrasonic NDE testing signals to improve characterization and evaluation of materials.
