Читать книгу Vibroacoustic Simulation - Alexander Peiffer - Страница 60

In acoustics we stay in most cases in the linear domain, so we change the notations from equations (2.20)–(2.22):

(2.32)

Equations (2.27) and (2.30) define the mathematical law for the propagation of waves. For the explanation of basic concepts the wave equation is used in one dimensional form.
