The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRACT

We analysed physical and geometric characteristics of larynx and adjacent to it cavities from aerohydromechanic point. Physical model of this part of the respiratory system was built on the basis of this analysis. We developed the experimental methods that allow one to evaluate aerodynamic resistance of the physical model as well as spectra of noise, generated by the airflow along the model. We obtained a vast number of real data. Analysis of this data allowed us to draw a number of important laws. In particular, we showed that aerodynamic resistance of diaphragm, which modells the glottis, depends significantly on shape and dimensions of the last. We found out that as degree of symmetry of the glottis shape decreases and its area increases the aerodynamic resistance of diaphragm falls. It was shown that level and nature of spectra of noise generated by the airflow passing the glottis depends on shape and dimensions of the glottis as well as on airflow speed. In particular, we found that the decrease in symmetry of the glottis shape, increase of its area and decrease of airflow speed result in decrease of integral level of noise generated by the flow.
