Morphology
The meaning 'an opening that lets sound reach the ear' is directly and compositionally derived from 'ear' (hearing organ) + 'hole' (an opening). This simple noun–noun compound follows regular English compounding patterns and is cross-linguistically common, so a B1 learner who knows both words will readily infer the MWE's meaning.
Etymology
The noun ear hole comes from the simple picture of a small hole placed next to your ear in a helmet or headset so sound can pass through. So, 'ear hole' means an opening that lets sound reach the ear.
