Fake rubber device singing birds

US scientists have successfully built a simple rubber device that is capable of reproducing complex birds' songs.

The Harvard University team said the song was born from blowing air through a simple rubber device .

Aryesh Mukherjee, a member of the research team, said: " The device has a very simple design. It is made of two rubber pieces attached to each other but to leave a small area in the middle to create ' sound groove "".

In addition to the supply of air, the device is attached to an engine that reproduces the operation of a stretcher. " In terms of physics, the sound track is just an elastic spring film. If you stretch it correctly and detect it in a fixed way, it will start to vibrate. Our project is aimed at The purpose is to control the frequency of such vibrations, "Mukherjee explained.

Scientists at Harvard University are now able to reproduce a lot of birdsong like the Bengale sparrow and are close to successfully simulating the song of the sparrow finch.

The results of the new study seem to be countering the idea that birds must learn complex neurological control processes to create distinctive chirps.

The song of birds - a complex sound filled with complex forms and rich harmony, has been the subject of many studies. For many years, neuroscientists have provided insights into how young birds learn to sing from adult birds - a capital that requires a series of complex neurological changes to help them control their voices. me

However, Mr. Mukherjee stressed, the results of the new study show that it is possible to reproduce bird songs without the need for a "high level of control ".

The team planned to share their project data with biologists to see if they could reveal a new way of how birds produce complex singing.
