Sound and Wildlife
In the wild, the ability to hear is so important for survival that no deaf vertebrate species are known to exist. In addition to producing sounds for communication, animals continuously detect sounds, even when they are asleep. Losing the ability to hear those sounds because of inappropriate or excessive noise can have serious consequences. It may mean missing the footfall of a predator or failure to adequately compare songs from potential mates. Appropriate soundscapes are important for animal communication, territory establishment, courtship and mating, nurturing young, and effective use of habitat. Scientific studies have shown that wildlife can be adversely affected by high levels of noise. Although the severity of the impacts varies depending on the species being studied and other conditions, research has found that wildlife can suffer adverse physiological and behavioral changes from noise and other human disturbances.
