Question

7. How is biodiversity affected by sound pollution?​

Answer 1

Explanation:

Noise pollution threatens biodiversity…

Contrary to what one might think, anthropogenic noise affects not only sensitive species directly exposed to intense sounds, but also many terrestrial and aquatic animals that inhabit very different ecosystems, often distant from human clusters. Although noise responses depend on the species, its negative effects, for terrestrial animals, may begin to appear as low as 40 dB [1]. Not only the intensity of sounds is important here, but also e.g. the frequency of the wave.

noise pollution

Noise pollution can change animal behavior and even affect their physiology. As a consequence, reduced reproductive success, higher mortality and intensified migrations among many animal species are observed. Such disorders strongly affect biodiversity both within the population and within the ecosystems themselves. Today, at least 19% of nature protection areas covered by the Natura 2000 network are in areas around which noise levels exceed road, rail and air traffic thresholds set out in the environmental noise directive.
