In the 19th Hangzhou Asian Games in 2023, Nanjing Xianghui Intelligent Technology Co., Ltd. undertook the provision, installation, technical support, and debugging of audio equipment for the Grand Canal Asian Games Park in Gongshu District, Hangzhou.
The Grand Canal Asian Games Park in Gongshu District is a sports complex that integrates parks, venues, and businesses. The total area of the park is 701 acres, with a total construction area of approximately 185000 square meters and a total investment of approximately 2.9 billion yuan. In addition to the field hockey arena, it includes a table tennis arena with 6928 seats and a field hockey arena with approximately 5000 seats. As the table tennis and hockey arena for the 2022 Hangzhou Asian Games, the Grand Canal Asian Games Park will become a comprehensive sports park that meets various sports needs.
      The design inspiration for the table tennis hall comes from the jade object "cong", which was analyzed and optimized by the architect in BIM form, forming a beautiful intersection. Combining the characteristics of silk, the curved layout of the gymnasium increases the difficulty of designing and installing the sound reinforcement system.
This project uses SOUNDKING TS series coaxial adjustable directional speakers and FW series remote horn speakers at the bottom of the hockey field, arranged in a grouped lifting manner under the curved grid, effectively covering the entire competition field and audience seating area.
Full horn radiation, higher sound pressure level, and wider sound range. The fiberglass box structure has higher strength and lighter weight, and is designed with all-weather waterproofing to cope with various weather conditions. The carefully designed hanging system facilitates installation and angle adjustment.
       In order to avoid sound focusing defects caused by direct reflection of sound waves due to the curved dome design, the table tennis hall has installed six sets of G series 10 inch linear array speakers in a circular manner under the screen, which not only achieves uniform coverage of the effective sound amplification area, but also ensures high sound pressure level and speech clarity while avoiding harmful sound reflections, ensuring the sound pressure level and language clarity of the competition sound amplification.
      In December 2022, Gongshu Canal Sports Park won the 2022-2023 China Construction Engineering Luban Award.

      The Harbin Grand Theatre is located on Sun Island on the north bank of the Songhua River in Harbin. Including 1600 seats in large theaters, 400 seats in small theaters, underground garages, and ancillary facilities, the total investment is approximately 1.279 billion RMB. The architectural designers are MAD Architects and Beijing Architectural Design and Research Institute. The architectural acoustics, sound reinforcement system, and stage lighting designers are all from the Acoustic and Theater Special Design and Research Institute of East China Architectural Design and Research Institute Co., Ltd. The construction unit for sound reinforcement, stage supervision, interior communication, lighting prompts, and video systems is Nanjing Sunfair Intelligent Technology Co., Ltd.
      The newly built Harbin Grand Theater is not only an international standard theater that can meet the needs of musical and symphonic performances, but has also become a landmark cultural building in Harbin. The Songhua River's tides rise and fall, flooding and freezing leave traces of its changing and alternating processes, while the surrounding flat plain environment highlights its undulating streamline. Considering the needs of viewing and sightseeing, the Grand Theater has adopted the world's first method of introducing natural light into the theater, enriching the lighting methods during non performance periods and creating a new energy-saving and environmentally friendly model; The streamlined design of multi island stands in the theater is consistent with the overall style of the building's exterior design; The small theater innovatively adopts a rear opening stage, with outdoor scenery as the stage background, providing the audience with a novel viewing experience; A unique pedestrian sightseeing corridor and viewing platform have been set up in the grand theater, allowing visitors to overlook the surrounding wetlands and appreciate the unique natural wetland scenery of Harbin.
      The renowned architecture news website ArchDaily is also known as one of the world's most popular architecture websites, with many of its readers being architects from various countries. 55000 readers responded to the call and selected the top five in 14 categories from over 3000 buildings published on the website last year. Then, the website will select the best works of the year. Among them, Harbin Grand Theatre won the Best Cultural Architecture award, which is also the only award-winning building from China in this selection.

      The architectural design of Harbin Grand Theatre was jointly carried out by Beijing MAD Architectural Firm, which designed the "Toronto Marilyn Building", and Beijing Institute of Architectural Design and Research, which designed the "National Centre for the Performing Arts". Audio and video engineers from Nanjing Sunfair Intelligent Technology Co., Ltd. have created a high-quality theatre for the people of Harbin here.

      Ningbo Dongqian Lake Academician House is located at the foot of Taogong Mountain beside Dongqian Lake. It is planned and designed by Wu Zhiqiang, academician of the Chinese Academy of Engineering. It will be officially opened in 2020. The project takes advantage of the renovation and expansion of the former building space of the historic famous Ningbo Normal University. With the concept of "mountain · water · village", "Hall · corridor · House", the project perfectly integrates the natural landscape with humanities and art, and creates an international first-class academician center with high quality, high standards and high positioning to meet the needs of academician scientific research innovation, exchange and discussion. It will become the tipping point for the development of science and technology, culture and economy in Dongqian Lake region and even Ningbo City.
