Vuvuzelas, The Annoying Things, But Has Become The Hallmark Of FIFA World Cup 2010 South Africa

During the World Cup 2010 in South Africa, Vuvuzelas have become one things that always used by the people to support their country. Vuvuzelas has become the hallmark in this four years event. The plastic trumpets becomes more annoying as the World Cup reach the final.

The sound of Vuvuzelas like a straigtened trumpet, the player sending puffs of air into the tube that excites resonance of the air in the conical bore. When its played by a professional trumpeter the sound of Vuvuzelas is reminiscent of a hunting horn, but when it played by the football fans, you know what happens, the note is imperfect and fluctuates frequency. The sound more like a n Elephant trumpet. This happens when Vuvuzelas is played by an average people they doesn't keep the airflow and motion of the lips consistent.

You can imagine when hundreds of Vuvuzelas are played together. What you get is the distinctive sound. The football fans are blowing the Vuvuzelas at different times and in varying frequency. The sound is very annoying and rather like the sound of thousand insect flying in your ear.

Why the sound of Vuvuzelas are so Loud?
Its can be explained by the shape that is roughly conical, and flares. Vuvuzelas believes creating sound frequency of 235 hertz, and its generates harmonics sounds at 470, 700, 940, 1171, 1400, and 1630 hertz.

For your knowledge a flared instrument has louder higher-frequencies harmonics than a cylinder instrument, because the higher harmonics are at frequency where our hearing is most sensitive. This is why the conical saxophone sounds louder than the cylindrical clarinet.

According to the Departement of Communication Pathology at the University of Pretoria, South Africa, the prolonged exposure of the Vuvuzelas poses a risk to hearing, the instrument it produces 116 decibels at 1 metre. Listen to one Vuvuzelas for just 7 to 22 seconds and you will exceed similar permitted levels for noise at work. Even the whole crowd produces at higher levels, and some test at a training match shown temporary disturbed hearing loss among spectators.

The more louder sounds are more annoying. Our hearing is a sensitive early-warning system, we respond to event sudden changes in the sounds around us which might indicate threats, persistance noise, ignore benign. As the sounds loud as a Vuvuzelas, it becomes harder to habituate to the sound.

Well, aside of annoying Vuvuzelas, I thinks the best way to deal with this situation is to fully enjoy the atmosphere. Once you can combine the atmosphere and the existence of the Vuvuzelas, then you can fully feel the highest feeling to be part of the history of the World Cup.
