2019 Double 11 "Cat Night" Carnival Night, a shocking audio-visual feast
On the evening of November 10, 2019 tmall double 11 carnival night was held in Shanghai Mercedes Benz cultural center, with 86 groups of stars from all over the world, bringing an international level performance. With the theme of "win-win with the world", the party is divided into five chapters: "civilization", "prosperity", "happiness", "struggle" and "future".
In terms of dance design, for the first time, mobile stage and array of people are used in the indoor evening party to enjoy the experience of immersive viewing. The theme style of dance unlocks the new playing method of cat's head, and the emergence of the changeable and dazzling hexagon stage presents a shocking audio-visual feast for the audience!
Such a large venue requires a high level of stage acoustics. The sound design concept is to ensure the sound quality while minimizing the impact on the audience and live pictures. So the sound designer used 3D modeling software to carry out a large number of simulation analysis, and finally used different conventional three side platform speaker hanging scheme, so that the effect of the stage is more like four sides.
This kind of seemingly uncomplicated loudspeaker hanging scheme often depends on a very detailed design and careful combination of years of work experience. Because the stage platform is full of ground screens, placing ultra-low will destroy the vision of dancing beauty. Therefore, part of the bass is hung on the top of the full frequency speaker to ensure the uniform coverage of the whole low frequency, and the subwoofer is hung behind the main expansion to give the VIP audience a more shocking hearing experience. The hanging points of all speakers also fully consider the impact of dancing beauty design and lighting flying cats. Because the speaker line can not be directly lowered to the ground, the design team used a 130 meter long speaker line, and floated the speaker line to the back of the stage before sagging. Although the adjustment made to ensure the visual effect will cause some adverse effects on the sound, after careful debugging, the sound group will minimize these adverse effects. The final results are in line with expectations, that is, in close cooperation with dance, lighting, screen, flying cat and other parts to ensure the visual effect, but also get a very shocking sound effect.
