We obtain a set of equations for determining the distance from the chest surface to various sources (monopole, dipole, transverse quadrupole) of wheezing sounds in human lungs. During testing, we experimentally determined anatomically correct estimates for the distances to sources of wheezing sounds in the frequency range of 100–500 Hz. We demonstrate the possibility of resolving the distances to sources of wheezing sounds with different peak frequencies. We analyze the main limitations of the method. 相似文献
