Morphology
instantaneous + sound + pressure
The phrase combines transparent constituents — 'instantaneous' (at a particular moment), 'sound' (auditory vibration), and 'pressure' (force per area) — so its overall meaning (the pressure associated with sound at a specific moment) is directly derivable from the parts. Although the exact technical nuance (difference from average pressure) is specialized, the compositional adjective+noun+noun structure is regular and cross-linguistically familiar, so a B1 learner who knows the words would grasp the general meaning.
Etymology
The term instantaneous sound pressure comes from a simple image: instantaneous means 'at one exact moment', and sound pressure is the push or pull a sound wave makes on the air. So it describes the change in pressure at that single moment compared with the usual pressure at the same place.
