Vuvuzela "vuvuzela" is a horn with a length of more than 1 meter, which was used in ancient Africa to call a meeting of tribal members. The name vuvuzela means "making noise" in Zulu.
According to South Africans, "songbirds" were originally used to drive away baboons. As soon as the vuvuzela blew, the baboons couldn't stand it and ran away at once. If you haven't adapted to Wuwuzu before, you will probably feel dizzy and irritable when you listen to Wuwuzu for the first time. As long as there is a big football match in South Africa, almost all fans will blow horns about one meter long, and even South African locals can't stand it at all.
Hearing the World, an international hearing organization headquartered in Switzerland, has been committed to protecting hearing since its establishment. In June of 20 10, they completed the decibel test of the South African speaker "Wuwuzula", and the results showed that it could emit noise as high as 127 decibels. Beni, an audiologist of the organization, said: "Sound exceeding 85 decibels can cause deafness, and the noise decibels emitted by vuvuzelas are much higher than this, even exceeding the sound of chainsaws. We suggest that fans take certain measures, such as wearing earplugs. Because watching the ball for 90 minutes in such a high decibel environment is absolutely harmful to hearing and may even lead to permanent hearing loss. "
