Topics: TOA at the Beijing Olympics
Beijing National Stadium (The Bird’s Nest)Beijing National Stadium, also popularly known as the “Bird’s Nest,” was the main stadium of the 2008 Beijing Olympic Games. During the games, football and track and field events were held in this stadium, as well as the spectacular opening and closing ceremonies. The biggest issue in the installation of TOA’s systems was how to provide correct and accurate broadcasting that would allow for smooth game operations in a gigantic stadium boasting a seating capacity of as many as 91,000 spectators.
A combined broadcast system composed of the SX-2000 Series Matrix system and the VX-2000 Series Integrated Emergency Public Address system provides background music and general announcements. It also offers easy selection of multiple sound sources for free broadcast to multiple areas through a combination of HX-5 Series Variable Dispersion speakers and ceiling mounted speakers for smooth sound distribution. In case of fire or other emergencies, the system instantly connects to external public address equipment for evacuation announcement to ensure the safety of both spectators and participants. Additionally, extensive failure detection functions programmed into the system ensure that system troubles and failures can be quickly remedied.
After the Olympic Games were completed, the stadium was remodeled and the installed TOA systems are expected to be used in a wide assortment of future applications ranging from sports to music concerts and other entertainment events.
STADE DU FRANCE(France Stadium)As the main stadium of the 1998 World Cup soccer championships, many exciting battles have been played out at the famed Stade du France. Here, in addition to a general-purpose broadcast system, TOA installed its Matrix-based Voice Alarm* emergency PA system. Equipped with approximately 1,550 speakers divided into 16 zones of operation,the system is used for broadcasts throughout the entire facility,including the entrance area, outside parking lot, and the complex's offices and restaurants. With such features as a computer-monitored self-diagnostic function that quickly detects system failures and broken or shorted wires, its advanced design has made this system a reference standard for new emergency warning system safety regulations in France and the EU.
- The system automatically activates a set of pre-programmed Voice Alarms whenever an emergency signal is received from its connected fire alarm system. For emergency broadcasts to the arena, however, the timing of the messages can be manually adjusted to reduce the risk of panic.
Porsche ArenaPorsche Arena in Stuttgart, Germany, is a multi-purpose hall with a crowd capacity of 7,500. As well as being site for all sorts of sports including basketball, volleyball, tennis and ice hockey, the hall also regularly plays host to a wide variety of concerts and performances.
With its Line Array Speaker SR-A12, TOA has created a broadcast system that allows for voices to be heard clearly even when there are numerous conditions for reverberating sounds. Acoustics simulation software identifies the optimum speaker direction and placement to ensure the finest possible clarity and a high level of acoustic pressure.
And apart from broadcast systems for functions, TOA also looks after the safety of audiences with the VX-2000 series, its independent emergency broadcast public address system.
Hakuba Ski Jumping Stadiam in NaganoSki jumping stadiam in Hakuba Village were the stage that profoundly moved the Japanese people in the Winter Olympic Games in 1998. TOA's broadcast system was used for a huge course having both the Large and Normal Hills. Now, it offers comfortable sounds to music concerts and other events, not to mention announcements for jump contests.
Copps ColiseumCopps Coliseum, located in Hamilton, Ontario, is the base of Canada’s Hamilton Bulldogs ice hockey team. TOA installed a total of 44 HX-5 Series Variable Dispersion speakers suspended from truss beams to provide true-to-life sound that augments the action in the stadium.
Yokohama International Swimming PoolOne of Japan's largest indoor swimming facilities having an international official swimming pool that can accommodate up to 4,000 audience. TOA supplied a sound system for the swimming pool, an emergency PA system for the whole facility, and a surveillance camera system for operation and security purposes. TOA totally supports the operation to make it safer and more efficient.
HOME'S STADIUM KOBEThe large, silvery roof of HOME'S STADIUM KOBE resembles a bird spreading its wings, hence its name. Because the stadium is designed to be used exclusively for such ball games as football and rugby, it has no track around the pitch, thus providing spectators with a closer view of the games.
To install the most ideal sound system in this stadium, we carefully examined the reverberation times and maximum sound pressure throughout the entire stadium from the perspectives of both architectural and electric sound acoustics, with repeated simulations performed before installation. Employing a digital console and a digital processor as a nucleus, the system permits all of its operations to be controlled from a central sound control room, and facilitates the creation of the most appropriate sound systems for individual games. The system also features a special function that suppresses noise heard in surrounding area to a bare minimum.
In the FIFA World Cup 2002 jointly being held in Japan and South Korea, TOA's sound system will present all the emotion and excitement of the football stadium in terms of its sound presentation.
