The Stadium in Cape Town, made by German engineers, is the world’s first soundproof.
The stadium has a capacity of 69,070 seats, you can realize what will be there.The sound isolation was made with a transparent roof made up of 9,000 glass panels, arranged in a circle above the seats.
To reflect the sound inside the stadium, from the panels have been caught some Teflon nets and fiberglass.The roof will not only help create a unique atmosphere, but also will protect the spectators from the unpredictable weather phenomena: rain, strong wind, even storms.
The roof’s shape is concave and diverts the wind around the stadium.
