The sound of a human being acts like a jet engine

Researchers have discovered an incredible correlation between the way air flows in a jet engine and the way the human larynx makes sound.

The basic principle for creating sounds is easy to understand. The nerve cells that stimulate the muscles pull the vocal cords together. The interaction between air and vocal cords makes these strings vibrate to produce sound.

According to Sid Khosla, the lead author of a study published in detail in the March issue of the ENT Journal, this is the only mechanism involved in sound production. then each person's voice will be very mechanical. Therefore the details related to how the airflow affects the sound production and the quality of the voice are also the reasons why each person's voice is different.

Tornadoes, which are circular motion areas that look like smoke rings, can turn into chaotic motions that can produce sound in jet engines.

Khosla explained to Livescience, 'we are wondering if tornadoes can produce secondary sounds in the larynx.' In the tornado larynx produces sound by interacting with structures located above the vocal cords.

Khosla said these tornadoes were introduced in mechanical models and mathematical models but until now no one could describe or see them in animal models. Therefore, Khosla and his colleagues did this by studying this model on dogs.

Khosla explains: 'The dog's larynx is most similar to the human larynx.'

Understanding how the sounds produced in this new model can give hope to people with speech-related diseases.

Khosla said: 'Currently, surgery is necessary to treat speech-related diseases and surgery is usually done on vocal cords. If you understand other sources that affect sound, you can develop a whole new way to treat speech-related diseases. '
