Few days from now, some 69,000 fans will be screaming out of their lungs in the World Cup 2010, held at South Africa’s Cape Town Stadium. As many of the surrounding residents voiced, they’re concern of the immersed sound coming from the stadium during the event, thus some clever engineers from Germany answered their call by integrating some marvelous design into this stadium.
The open-air stadium which sits at Cape Town’s tiny Green Point neighborhood is known as a soundproof stadium. A very weird nickname for a stadium isn’t it? But it just does as it is known. Engineers from Schlaich Bergermann placed some half-inch thick glass panels on top of the 398,265 square-foot roof, hold by some fiberglass and Teflon mesh to support the glass, forming a ring-like roof on top of the stadium. The results showed that the crowd’s roar will be reflected back onto the field, giving them the spiritual encouragement while preventing the massive roar from leaking out of the stadium.
