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

RÉSUMÉ

The solution of the problem of sound propagation in a structure consisting of a junction of a plane and of a wedge-shaped waveguide is constructed. The parameters of the distribution are represented in terms of eigenfunctions of the two waveguides. Matching of the fields of the two waveguides is achieved by introducing an intermediate domain in the form of a circle segment. The introduction of this domain allows rigorous matching of the acoustic fields in waveguides with different geometries. The dependence of the energy coefficient of transmission of sound through the matching zone on the waveguide parameters and on the attendant restructuring of the acoustic field is investigated. Conditions of acoustic radiation of a piston located in a plane waveguide with a horn are analyzed.
