Have you ever stopped to listen to the sounds of nature? From the chirping of birds to the rustling of leaves, every sound contributes to creating the unique acoustics of an ecosystem. However, experts international organizations are raising a worrying alarm: these sounds are fading quicklyand without urgent action, we risk losing these “acoustic signatures” along with the biodiversity that produces them.
Technology has made sound an increasingly important way to measure the health and biodiversity of ecosystems. Scientists using ecoacoustics to evaluate habitat And species they detect a growing silence in thousands Of habitat, witnessing extraordinary losses in species density and variety. The result? An “acoustic death” that reflects a catastrophic loss of life.
Examples of a world that is losing sound
- Forests: The trees burned in Lassen Volcanic National Park in California in August 2023 are just one example of how more intense fires are destroying ecosystems, even eliminating the sound of the animals that once populated them.
- Oceans: During the Cold War, the US Navy used underwater surveillance systems to track Soviet submarines and found that it was difficult to do so near coral reefs due to the sounds the reefs made. These sounds are now in danger due to increased coral bleaching events, which have already destroyed 80% of coral in some areas.
- Soils: Scientists are starting to listen to the sounds of the soil to find out more about its biodiversity. However, intensively managed lands, often treated with pesticides, are noticeably quieter, an eerie sign of the loss of life within them.
These changes are not isolated and are occurring in air, forests, soil and underwater. The decline of natural sounds is not only an ecological loss, but also has potentially serious implications for human health and well-being.
The emotional and scientific value of natural sounds
Sound is one of the most powerful triggers of human emotion, and acoustic memories are particularly strong. For many researchersthe disappearance of soundscapes is a source of pain, but also a tool to describe the beauty of nature and the need to preserve it. For a wider audience, listening to these sounds can be both comforting and extremely unsettlingbut above all it connects us to the reality of what we are face upndo.
In front of these testimonialswe can no longer ignore the impact of our actions on the environment. It is essential to literally listen to them warnings that nature is there sending through his silent changes.
And you, have you noticed any changes in the sounds of nature around you?
