Makarenkova A. Auscultation descriptions of sounds of breathing, methods of their registration and treatments.

The dissertation is devoted to the acoustic characteristics of human respiration sounds, their registration and treatment. The physical processes of transition of the sounds generated by the vital activity of an organism at receiving acoustic transformers are studied. The algorithms of construction of effective electro-acoustic transformers designed for auscultation of the respiration sounds are indicated. The obstacles of the transformers, electronic stethophonendoscope of sound, vibration and electromagnetic nature are studied, classified and ranged. The recommendations for the reduction of the obstacles are developed. The electronic digital data base of respiration sounds of verified patients healthy and ill with pneumoconiosis, totally 600 sound images, is formed. The computational treatment of the respiration sounds is performed. The sound artifacts of the patients with pneumoconiosis are discovered and objectified. The physical hypotheses for generation additional respiration sounds by patients with pneumoconiosis, caused by the morphological changes in lungs, are offered.
