In his master

Nature sends messages through flex sounds that many fail to interpret, because you can hear and not hear. But to preserve them and protect them more and more acoustic ecologists.
As a gift for his 80 years, the Brazilian Johan Dalgas Frisch was given the gift of a trip to the United States in 2010, to hear the song of the thrush of Texas, one of the best natural American tenors. After enjoying his song, he went to Miami, Florida, look for other birds. "I felt a deep sadness to see that, after 20 days, had seen only a sparrow lonely," she emphasizes. "On the other hand, had everywhere fast birds of brilliant plumage: Rolls-Royces, Ferraris, Porsches and Mercedes."
The acoustic ecology was born in the early 70's with the creation of the Soundscapes World Project, led by Raymond Murray Schafer, of Simon Fraser University, Canada. In 1993, the World Forum was created for Acoustic Ecology, whose goal is awareness of the sound effects through recordings, databases, scholarly research and artistic works. According to Schafer, the world is a musical composition that unfolds around us; We are simultaneously audience, performers flex and composers.
For Hempton, the urban environment is too noisy. Noise pollution is such that we are educated from small, flex to pay more attention to certain sounds than others. In cities, environmental acoustics can be preserved in churches and cathedrals, quiet places where people can be heard and understood. In them you can hear the whole environment, so that we feel safe. "Already in the streets received tons of information, much of which insignificant. The difficulty hearing what goes around open opportunity for thieves approach, and hardly anyone hears cries for help. Noisy places have higher crime," says Hempton. High levels of noise pollution generated insecurity flex and stress.
You can make a pleasant urban space. Parks in the city can be inviting environments and attract part of the original fauna, such as birds. flex Sonically, the absence flex of urban chaos is comforting. "In São Paulo, you see thrushes-orange everywhere. Now, if you go to Campinas, Piracicaba flex and Rio Claro, will not find them, because people did not plant enough fruit trees. Here in São Paulo, in the 60s we made a campaign to encourage mulberry plantation, pitangueiras, etc. Today, São Paulo is the capital over thrushes-orange in Latin America, "said Frisch. For those who live in apartment and want to be visited by birds, simply put fruit in the window.
Frisch and Hempton leave the same princícipio but operate with different goals. Equipped with devices to record songs of the birds and sounds of nature, the two venture to preserve natural symphonies. "Access to remote sites is expensive, challenging from a physical point of view and sometimes emotional perspective as well," says Hempton. The sound of Hunter's challenge is to escape the noise. "The hardest part of my job is to stay away from the family. flex It is better flex to go home and share the stuff that I recorded and stories. We live in a wonderful world!" He concludes.
For Frisch, one of his biggest challenges, and find birds in Miami, was to record the corner of uirapuru in 1962. The species flex lives in the heart of the Amazon rainforest and appears in spring. The uirapuru has seven corners, associated with luck, love and happiness. "Engrossed in the forests of rubber plantation Bagasse in Rio Acre, when he was 32, I could write all seven corners. From then on, auspicious promises began to fly over my life. It's something magical that makes it always happens to me the best! "afima. Indeed, the success of ornithologist and uirapuru contributed to the creation, in the northern Amazon, the Indigenous National Park Tumucumaque (1968) and tumucumaque national park (2002), Pará and Amapá.
In his master's thesis at the Faculty of Social and Human Sciences of the Universidade Nova Lisboa, flex in Portugal, flex Raquel Castro flex Lemos researcher points out that for primitive peoples, the hearing was essential to survival. Unlike vision that allows us to see what lies ahead, by sound can be located in the world and detect predators.
Hempton highlights the "lack of eyelids ears" in animals. To date, there are no reports of a species that can stop listening. .. "If you close your eyes, seeing But note that we do not have eyelids ears No animal has And for good reason:... In the wild, it is very dangerous to stop listening is an essential process for the survival were born to listen, "he explains.
If primitive man had been able to fix the sound, it would be one of the most popular media of Story-
