声学边界元模型用于模拟肺实质和周围胸壁中的声音传播。它在理论上和数值上得到了验证，然后与模拟气胸肺部病理学的肺胸体模模型的实验研究进行了比较。研究量化了模拟肺部病理学对在模型胸部表面测量的声场的影响。这项工作与躯干内肺部、血管和心脏声音的先进听诊技术的开发相关，该技术利用多个无创传感器来创建声音生成和传输的声学图像，以识别某些病理。
An acoustic boundary element model is used to simulate sound propagation in the lung parenchyma and surrounding chest wall. It is validated theoretically and numerically and then 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 measured at the phantom chest surface. This work is relevant to the development of advanced auscultatory techniques for lung, vascular, and cardiac sounds within the torso that utilize multiple noninvasive sensors to create acoustic images of the sound generation and transmission to identify certain pathologies.
