Your notation confuses me. Are you actually mixing subscript for components AND derivatives? Please don't do that.

From your source: "When these terms are absent the equation describes sound propagation from sources on the boundaries of the fluid, such as the vibrating cone of a loudspeaker." That is the same as Joce states.
