Development & Experimental Validation of Finite Element Simulation of Sound Transmission in Lungs & Torso
Measuring sound transmission in the torso and lungs may be of value if altered transmission patterns correlate with pathology in ways that can be detected and used to provide a reliable and quantitative diagnosis of disease or injury. The aims of this dissertation research are to develop accurate subject-specific computational models, including human and animals, for simulating sound propagation in the lungs and torso. Models are validated by comparing with experimental studies on the lungs and torso. The developed computational simulation models may be of use in assessing the performance of acoustic approaches to diagnosis of injuries and diseases. This work is significant to the long-term goal of the “Audible Human Project (AHP)”, which aims to develop a computational acoustic model that would accurately simulate generation, transmission and noninvasive measurement of sound and vibration throughout the body caused by both internal and external sources. The outcome of it may also be useful in the development of a more effective educational tool for teaching stethoscopic-like skills in the future.
