Childish cries across a lion roar

Children look innocent and lovely but their cries are comparable to the roar of tigers and lions. These sounds are similar, but the young roars with much higher pitches.

The new study, which is published in the PLoS ONE journal, will help explain why it is difficult to ignore all the nerve-damaging sounds of most of these mammals.

'The roar is very similar to the sound of children crying,' said scientist Ingo Titze, director of the National Voice and Voice Center, 'In some respects, the lion is a larger clone. of a crying child, loud and loud but very low altitude '.

The results also help explain how domestic cats attract women by their cries. Everyone is 'defaulted' to the ability to react to a child's cries, especially women. The cat that sounds like a baby cries makes us react even when we don't want to.

Both the roar and the cry were meant to attract attention. Titze said a child cried so that people could help him. Lions use sounds that catch the same attention but mainly to convey the message: 'I'm here, this is my territory, get out of here now'.

'In both cases, we all hear loud, harsh sounds hitting people's ears. When a child cries, that sound is not lovely. Basically, that sound is very annoying. Oscillation is irregular, " he said.

Titze and his colleagues have identified a loud roar, the low frequency of large cats, which are also of such irregular nature, predetermined by the physical properties of the vocal fold tissue. These tissues are capable of stretching and deforming. Previously it was suspected that nerve impulses from the brain could help control these sounds.

For both large and young cats, folding tissue or larynx are very loose, irregular vibrations make the roar sound uncomfortable. The main difference is that children cry at high frequencies while tigers roar with low frequencies.

In relation to the cat species, the new study denies the notion that large cats like this because they have large larynxs.

'We are trying to clarify the previous hypothesis that lions and tigers roam with low fundamental frequencies because they have giant vocal fold tissue,' study co-author Tobias Riede told Discovery.

'They actually have large vocal folds, but their shape and viscous properties (elasticity and elasticity) make their roars loud and deep ,' he said. 'We have studied many species. animals like deer, deer, dogs and cats Lions and tigers are interesting examples of very loud and low frequency pronunciation.

Some other interesting results from the new study: the roar of tigers and lions can reach 114 decibels; the roar of tigers and lions is 25 times louder than the sound of lawn mowers; Big cat family roars 50 times every 90 seconds.

'They roar with sound that scares people because it's very rough and hard to hear,' says Titze. 'Lions and tigers are said to be kings of animals in part because of their roar. Imagine if you played beautiful melodies and very low frequencies, no one would be afraid of them. '
