Morphology
The compound is directly compositional: 'acoustic' means relating to sound/hearing and 'meatus' means an anatomical passage, so a learner who knows both constituents can infer it denotes a passage related to hearing (i.e., the ear canal). Although the term is technical/medical, its meaning follows transparent lexical components and similar Latin-based formations in other languages, making it predictable for learners who know the parts.
Etymology
Acoustic meatus comes from two old words: acoustic meaning 'sound' and meatus meaning 'passage'. Picture a small passage that carries sound from the 'outer ear' to the 'eardrum', so the name simply describes the ear passage that leads to the eardrum.
