Sound Waves

Sound Waves

Sound waves can be thought of as fluctuations in the pressure of a medium through which they propagate. Since the pressure also makes the medium's particles vibrate along its direction of motion, the waves can be modeled as the displacement of the medium's particles from their mean position.
Sound waves are longitudinal in most fluids because fluids cannot sustain any lateral pressure. In solids, however, shear forces help in propagating the disturbance in the lateral direction as well. Hence,...

This study uses an acoustic boundary element model to simulate lung sound propagation, validating it with phantom experiments of pneumothorax. The findings aid in developing advanced auscultation for diagnosing lung conditions.

Area of Science:

Biomedical Engineering
Acoustics
Medical Imaging

Background:

Lung auscultation is crucial for diagnosing respiratory conditions.
Traditional auscultation has limitations in spatial resolution and quantification.
Advanced acoustic modeling can improve noninvasive diagnostic techniques.

Purpose of the Study:

To develop and validate an acoustic boundary element model for simulating sound propagation in the lung and chest wall.
To investigate the impact of pneumothorax on acoustic fields measured at the chest surface.
To support the advancement of noninvasive acoustic imaging for diagnosing thoracic pathologies.

Main Methods:

Development of an acoustic boundary element model for lung and chest wall sound propagation.
