Morphology
The phrase combines 'ground' (a reference or baseline in electrical/audio contexts) with 'noise' (unwanted signal), so a learner who knows both words can likely infer it refers to background or baseline noise in a system. However, the precise technical sense—that the noise is tied to the electrical ground/reference and inseparable from the desired signal—requires domain knowledge beyond everyday vocabulary, making the relation only partially predictable.
Etymology
Ground noise may come from the image of a wire or device touching the ground, meaning the earth or a ground wire, and picking up a low, unwanted noise that mixes with the wanted sound. So, ground noise means 'unwanted background noise' that becomes part of the signal and cannot be removed.
