Morphology
The term is a straightforward noun-noun compound where the meaning is the pressure associated with or caused by sound; a learner who knows 'sound' and 'pressure' can infer it as pressure related to sound. This compositional logic is common cross-linguistically (e.g., Spanish 'presión sonora', French 'pression acoustique'), so the sense is transparently derivable without specialized exposure.
Etymology
The term sound pressure comes from a simple picture: think of sound as waves that push and pull the air, and pressure as the push on your ear or on a microphone. So sound pressure is the size of that push from a sound, and that's why we measure it to know how 'loud' a sound is.
