Morphology
This is a straightforward adjective + noun composition: 'anechoic' (without echoes/absorbing sound) modifies 'chamber' (an enclosed space), so a learner who knows both constituents can infer 'a room that absorbs sound reflections'. The pattern follows normal English composition and has clear, cross-linguistic parallels, making the meaning immediately derivable from the parts.
Etymology
Anechoic chamber gives a clear picture: an- means 'no' and echo means 'a sound that bounces back', so the room is made with special panels that soak up sound instead of letting it echo. That's why it means 'a room that absorbs sound'.
