Frequently during its lifetime a human organism is subjected to the acoustical and similar to them vibrating impacts. Under the certain conditions such influence may cause physiological changes in the organs functioning. Thus the study of the oscillatory mechanical impacts to the organism is very important task of the numerical physiology. It allows to investigate the endurance limits of the organism and to develop protective measures in order to extend them. The noise nuisances affects to the most parts of the organism disrupting their functions. The vibrating disturbances caused to the lung function as one of the most sensitive to the acoustical impacts is considered in this work. The model proposed to describe the air motion in trachea-bronchial tree is based on the one dimensional no-linear theory including mass and momentum conservation for the air flow in flexible tubes similar to the model of blood flow in large vessels [
]. It combined with the single-component model of alveole [
]. Two types of vibrating impacts were simulated that affect the thorax and the nasopharynx. The conducted simulations allowed us to detect two resonance frequencies that lay in the ranges from 3 Hz to 8 Hz and from 40 to 70 Hz when the thorax was affected (fig.1). For the nasopharynx disturbances no resonance states were found.
