Abstract
Acoustics as a science studies the movements of the compressible liquid, namely oscillatory movements, which are called sound (acoustic) waves. An acoustic wave is an alternating compression and rarefaction of the medium through which it propagates. The main local characteristics of acoustic waves are 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.
