Morphology

sound + off

The verb 'sound' clearly means 'to make a noise', so part of the MWE's meaning is directly derivable; however the particle 'off' does not inherently mean 'to begin', and its contribution here relies on verb–particle patterning (compare 'kick off', 'start off') rather than straightforward compositional logic. Because the sense 'to begin to make a sound' is only partially predictable from the parts and depends on phrasal-verb usage, this is best classified as semi-transparent.

Etymology

Sound off also comes from the picture of trumpets or horns giving a loud first note to mark the start of an event. That's why sound off can mean 'to begin to play or make a sound, especially to mark a start'.
