Shanghai Stadium strengthens its sound with Bose Professional

This renovated stadium in China has trusted ArenaMatch DeltaQ speakers from Bose Professional as a sound reinforcement system, which now covers all seats to offer a better experience to fans.

Soccer team headquarters The Shenhua FC, he Shanghai Stadium, with capacity for 72.000 spectators, It has become a benchmark of innovative Chinese architecture after its remodeling to turn it into a specific venue for playing soccer., in compliance with the standards established by the FIFA.

In this sense, highlights his corrugated roof, that simulates the shape of a saddle; a visually spectacular element, but that has posed a great acoustic challenge for those responsible for integrating the sound reinforcement system: the chinese company BNC Technology and the local team Bose Professional.

The new roof follows the undulating line of the stands, rises to the 70 meters in the west area and goes down to 30 meters high in the goal area, to create that saddle look. The inner edge of the perimeter cover is formed by a Transparent Led Screen 16,5 metros wide.

Since the beginning of the sound reinforcement system project, The size and unusual shape of the stadium raised a number of acoustic challenges, since the combination of materials, surfaces and the ceiling structure created reflections that muffled sound and generated opposite effects.

Besides, the ceiling structure itself predetermined both the location, position and weight of the line array speaker modules that had to be used, to which was added his installation at different heights, between 30 y 60 meters above the public,

In order to design a system that offered consistent sound, clear and powerful, with a uniform sound field over such a large surface, while meeting these strict specifications and stadium design requirements, BNC Technology specialists and Bose Professional engineers used the Modeler simulation software from this manufacturer.

This program 3D modeling facilitates acoustic design and analysis, as it examines architectural plans and material specifications. Modeler allowed the team to create different models of speaker configurations and locations to evaluate the option that offered coverage, optimal sound pressure level and intelligibility.

After a thorough analysis and virtual acoustic modeling tests, were selected ArenaMatch DeltaQ speakers for stadium sound reinforcement system, with the installation of 32 independent speaker modules, with sixteen arrangements oriented towards the public area and the other half towards the playing field.

All Bose Professional ArenaMatch DeltaQ speakers are powered by sixty PowerMatch 8500N amplifiers, that manage three procesadores ControlSpace EX1280C Networked to redundant Dante systems.

ArenaMatch DeltaQ technology makes it easy to create outdoor speaker arrays, that offer uniform and intelligible sound for all attendees, with different models designed to deliver specific horizontal and vertical coverage.
