1. the study of the generation and propagation of sound specifically in an atmosphere
Hartvigsen said Dr. Ford's visit was significant to him in another way. “I have been involved in some of the tests of the shuttle external tank hardware that were performed at AEDC over the last several years,” he explained. “I have some knowledge of aeroacoustics, vibration and the associated hardware that came in handy for the NASA shuttle tests.”
