The most horrifying noise

What is the most annoying noise for humans? Trevor Cox, an expert in sound applications at Salford University, throughout 2006 consulted about 34 types of sounds that make people most allergic (website www.sound101.org).

(Photo: webpanel, TTO) The result: the most annoying noise is vomiting (though this website is not a natural sound that is created by technical experts); the sound of clawing nails on the board, dentist's teeth drilling, children's cries (up to 1.1 million votes for these sounds). Next was the screeching of the microphone, the squeaking of the carriages on the tracks and the cry of the cat at night with the ringing of the cell phone. Meanwhile the snore is only in position 26.

The study also showed that there is a gap between men and women in receiving these sounds. In which women tend to be sensitive to about 25 unpleasant sounds, while men are most likely to get irritated and scared. 'Maybe it's because the role of women is to protect themselves and their children, so they are calmer before their cries' - Cox explained.

In general, the most frightening noises in ordinary society are the coughing, yawning, spitting, whirling chewing . Cox says: 'From a scientific point of view, we cannot understand at Why do some sounds creepy with people like that, but it is our reaction to those sounds that make us human. '
