Morphology
The meaning is directly built from 'noise' (unwanted/random data) plus 'level' (amount or magnitude), so a learner who knows both words can infer 'noise level' as the amount of noise present. This compositional pattern is common and cross-linguistically transparent, so it should be immediately understandable to a B1 learner familiar with the constituent meanings.
Etymology
Noise level in electronics uses the same picture: noise is random static or background 'chatter' that can hide the real data and level is how strong that background is. So it means the 'amount of random variation or interference' that makes a measurement or signal less clear.
