Noise is any factor degrading signal detection or discrimination

Evidence

Noise is a voluntary or involuntary sound that when added to a signal reduces the capacity of that signal to be correctly perceived and interpreted. In an animal communication context, the noise is defined as “any factor that reduces the ability of receiver to detect a signal or to discriminate one signal from another” Brumm and Slabbekoorn (2005). — Almo Farina, Soundscape Ecology, 1238
