Morphology

round + window

The noun phrase is a straightforward composition of 'round' (circular) + 'window' (an opening), so a learner who knows both words will naturally interpret it as a circular opening. Although the term has a specific anatomical referent (a membranous opening in the ear), that specialized meaning is a predictable, narrower instantiation of the literal composed meaning rather than an idiomatic shift.

Etymology

Round window comes from how it looks: a small, round membrane that acts like a tiny window into the inner ear. It is called that because it lets sound move into the cochlea, so the name helps you remember it is a 'small opening' important for 'hearing'.
