Morphology

acoustic + absorption

The phrase is compositionally built from 'acoustic' (relating to sound) + 'absorption' (the process of taking up energy/substance), so its meaning — materials absorbing sound energy — is directly derivable. It follows a regular noun–noun technical compounding pattern common across languages, so a B1 learner who knows the constituents would understand it.

Etymology

The term acoustic absorption uses a simple image: acoustic means 'sound' and absorption is like a sponge soaking up water. So, when a material soaks up 'sound' instead of letting it 'bounce back', it 'takes in sound energy' and reduces echoes.
