Birds chirp to mark their place and defend themselves, but a new study confirms that the chirping of birds acts as a tonic for the human ear, which makes human beings happy, even the recording of their voices has the same effect.

Although the growing volume of research has shown that time spent in close proximity to nature is beneficial to human health, some studies explain why this happens.

A team from California Polytechnic State University, in their research, sought to find out what made the sound of birds singing so that humans could experience the experience of living in remote areas and the sounds of birds.

Daniel Ferrero, a biology graduate student who led the study, said that there is a lot of evidence that spending time in nature has a positive effect on human nature. However, some studies have highlighted some specific features of the benefits bestowed on human beings by nature.

‘Although it takes a number of human senses to examine the restorative properties of nature on a large canvas, our study is the first experimental process in this field to work on just one sense and aims at the importance of human experiments in nature.

Ferrero and his team played recorded sounds of a variety of birds on hidden speakers during two sections of the trails at the Boulder Open Space and Mountain Parks in Colorado.

The investigative team played bird songs during a trail section in the weekly blocks and shut it down in another.

Although the birds’ chirping was a recorded sound rather than a reality, those who heard these extra sounds reported a better physical condition than those who did not hear them.

The results of the survey showed that both voices, themselves and people’s opinions about biodiversity can increase feelings of well-being.

People who hiked on the first section of the trail heard more bird sounds, but they did not comment on whether they thought there were more birds in that part of the trail. ۔ But hikers who heard more bird calls on the other side said they thought there were more birds in that part of the trail, and researchers found that thinking about more species was the real reason to feel better.

Clinton Francis, a professor of biology at the University of California Polytechnic, who reviewed the study, said: “We are visual animals that try to sense their direction by sound.

“I’m still amazed at how people feel better when they hear these sounds for just seven to ten minutes,” Clinton said. It really shows how important hearing is to us and perhaps to other animals. ”

Scientists say the findings show the need to improve natural soundscapes in and out of protected areas.

“By reducing human noise pollution, we can make it easier to hear natural sounds, including the songs of birds, which will make us happier,” the researcher said.

This research is published in the Royal Society B.
