Without considering its energy loss, the total incident pressure of a sound wave equals its total outgoing sound pressure. As an initial incident sound wave with a pressure of P 0 (solid black line) propagates from material A to material B, there is an increase in the pressure of the primary transmitted sound wave, P 1 (solid blue line), …
