Global Warming years traveled Bryan Pijanowski around the world to every possible location – from the rainforests in Borneo and Costa Rica to the Sonoran Desert and the streets of Chicago – from microphones to provided. His goal: to record in a year, any sound that produces our planet. Pijanowski’s soundscape ecologist and wants the changing climate mapping by listening to Earth.

The sounds of birds , oceans, animals and traffic should provide information about the changing state of the natural world

Pijanowski’s gigantic collection of microphones start recording soon birdsong, oceans, animals, insects, traffic and any other sound on earth – and that for a whole year. An ambitious project, which ecologist at Purdue University in the American state of Indiana wants to collect on the changing state of the environment information.

If soundscape ecologist he studies how environmental sounds are related to each other. Listening to the world, according to him, can provide important data on the impact of climate change on nature.

The Global Soundscapes Project ‘was launched on Earth Day, a day when environmental organizations, people from 192 countries annually do think about their consumer behavior and its impact on the earth. According to news MNN thousands of people have since registered to contribute to the project. Their bit

The Soundscape Recorder app, available for iPhone and Android, anyone can record his ambient sounds. By expanding from these audio files every year, scientists can listen for patterns and changes in the environment, says Pijanowski.

Pijanowski is not the first to study nature through its sounds. In the 60s, the American musician Bernie Krause began recording for use in films. Sounds of the natural world Later he founded Wild Sanctuary, an organization that takes natural sounds and archives.

While listening to his recordings Krause discovered that there were patterns. Birds with a short cry adapted their singing between that of birds with a long call. Insects ranged their sounds, so they would not drown each other. His observations led him to the hypothesis that animals adapt to be supernatural sounds like storms and rivers and superhuman sounds.

Krause wondered whether disruptions caused by deforestation, pollution and invasive species would reverberate have in the soundtrack of a particular area. He tested that include. By the sounds of a forest in the Sierra Nevada for one year in 1988 The forest was cut down during that period. That left clearly heard in Krauses soundscape, which almost became silent.

We hold a stethoscope against nature and listening to the heartbeat of the environment

Researchers built since then further Krauses idea sounds and names of each kind of landscape – from mountains to oceans. Pijanowski is optimistic that these sounds will exhibit changes due to the effects of climate change. Over time Some types of search other regions, where they add their sounds to the natural soundtrack.

When Pijanowski a year has collected all earthly sounds that will be sorted on the basis of an algorithm. Ecologists study the sounds, and then look for changes. In an interview with The Verge his assistant Stuart Gage compare their work with that of a doctor. “With a stethoscope a doctor comes to know. Ten different things about your heart We’re holding a stethoscope against nature and listen to the heartbeat of the environment.”
