The results presented in this book could be of interest to readers from two aspects. Firstly, the possibility of significant expansion of the number of problems allowing the construction of full analytical representations for sound fields in the areas of complex shape was shown. The concept of the general solution of the boundary problem was formulated and its efficiency in solving different tasks was demonstrated. The second distinctive feature of the book is that considerable attention is paid to the analysis of the physical features of sound fields and their relation to the geometrical and...
