Morphology

acoustic + device

The meaning is directly derived from the adjective 'acoustic' (relating to sound) modifying 'device' (a manufactured item), so a learner who knows both words will infer a device related to sound. This adjective+noun compositional pattern is common and cross-linguistically transparent, making the MWE immediately comprehensible to a B1 learner.

Etymology

Acoustic device comes from the word acoustic, meaning about hearing or sound, and device, meaning a tool. Imagine a small machine that picks up, makes louder, or changes sounds, so it means 'a tool that works with sound'.
