Noise masks at least one of the three sound-source types

Evidence

Adopting the three categories of geophonies, anthrophonies, and biophonies, we can say that the noise is acoustic energy that in turn masks and interferes one of these three sound source types. — Almo Farina, Soundscape Ecology, 1234
