Computational models for simulating sound propagation in the lungs and torso are developed and evaluated. A theoretical model for sound propagation in the airways is developed and coupled with an acoustic boundary element model for sound propagation in the lung parenchyma and a finite element model for sound propagation in the surrounding chest wall. Models are validated theoretically and numerically, and compared with experimental studies on lung-chest phantom models that simulate the lung pathology of pneumothorax. Studies quantify the effect of the simulated lung pathology on the resulting acoustic field. This work is relevant to the development of advanced auscultatory techniques for lung, vascular, and cardiac sounds within the torso, and may be useful in the development of a more effective educational tool for teaching stethoscopic skills in the future.
