Morphology

sound + unit

The meaning "a unit used to measure sound" is directly and transparently derived from combining 'sound' (auditory phenomenon) with 'unit' (a measurement quantity). This simple noun-noun compounding follows regular English composition and has clear parallels in other languages, so a B1 learner who knows both words should be able to infer the meaning.

Etymology

The term sound unit comes from the simple idea of taking one sound and measuring it with a fixed unit, like putting different noises into equal boxes or steps so you can compare them. So sound unit means a standard way to 'measure' loudness or strength.
