Abstract
Violation of the function of breathing manifested in the form of snoring can lead to a decrease in pulmonary ventilation and a decrease in the level of oxygen in the blood. As a result, it is possible to develop a number of diseases, and even with a fatal outcome. The reasons for the appearance of snoring can be many, which complicates both the diagnosis and treatment of snoring. The creation of objective tools and methods for diagnosing snoring is possible in the case of creating an adequate physical model for air passage in the upper respiratory tract and describing the physical effects that arise in the process of breathing. The physical model of air ducts, created on the basis of the anatomical model, takes into account the influence of all structural elements influencing the passage of air. The appearance of sound during snoring is the result of the ingress of turbulent airflow into the oropharynx and subsequent vibration of the palatine tongue and the vibration of the surface of the soft palate. One possible perspective method for identifying the main cause of snoring can be a spectral analysis of the sounds of snoring.
