Abstract
The possibility to relate the nature of the forced expiration tracheal sounds with the sound radiation by a separated flow that arises in the region of dynamic trachea constriction during forced expiration is investigated. A mathematical model of forced expiration is used for estimating. The calculated form of the time dependence of the sound intensity during forced expiration qualitatively corresponds to the experimental dependence obtained experimentally for normal subjects. The results should be taken into account in the physical explanation of tracheal sound generation mechanisms and in the justification of using the tracheal sound characteristics in the diagnostics of human lung pathologies.
