The Mathematical Model of Acoustic Processes,re determined by such properties of the medium as temperature, pressure and concentration of impurities. The global properties of the propagation of these waves depend on the spatial and temporal distributions of the above factors, as well as on the shape of the medium boundaries, if any.
