Noise is not unwanted sound but information-poor spectrum useful for site assessment

Evidence

According to a soundscape perspective, noise can be defined as the portion of the acoustic spectrum that does not offer information per se, but the amount of noise and its distribution in time can be used to assess natural or anthropogenic events and to attribute a sonic quality to a landscape or to a site/location (see Fig. — Almo Farina, Soundscape Ecology, 1240
