Nanjing College of Media and Communications Selects Ruifeng Audio

      Nanjing University of Media and Communication is the former Nanguang College of Communication University of China, referred to as "Nanguang" and "Nanchuan". It is a provincial undergraduate university declared by the Communication University of China and approved by the Ministry of Education to run a new private university with an independent legal person in Nanjing, Jiangsu Province, and is also the only applied university of media arts in Jiangsu Province. On March 30, 2020, the Ministry of Education officially replied to the Jiangsu Provincial People's Government to officially convert the Nanguang College of Communication University of China to Nanjing University of Media and Communication.

      The multi-functional hall of Nanjing University of Media and Communication selected "RF" brand VK curve array system, SR multi-function series speakers, and peripheral equipment and other products. From the initial design of the project, to the in-depth design of "EASE sound field simulation analysis", and the final sound reinforcement effect debugging, RF Technology provides technical support services.

 

▲Left and Right Main Sound Reinforcement System：VK208+VK18B（8+2）

 

▲SR12 Multi-functional speaker

 

▲G11 wired gooseneck meeting microphone

 

 

      When designing the scheme, on the basis of fully grasping the functional positioning of the system, the engineers of Ruifeng Intelligence established a 3D model of the building for EASE according to the drawings and materials provided by Party A, and carried out the EASE acoustic simulation operation of the multi-functional hall through the computer, so as to make a pre-judgment and analysis of the actual engineering installation. Accurately calculate whether its sound field data meets the requirements of Party A, so that the budget allocation of the whole system is more reasonable.

      The multi-functional hall of Nanjing University of Media and Communication refers to the requirements of the acoustic characteristics of multi-functional sound reinforcement systems in the national standard "GBT 28049-2011 Code for the Design of Sound Reinforcement Systems for Halls and Stadiums".

      The project has passed the acceptance and put into use, the maximum sound pressure level of each frequency band meets the requirements of the first-class standard, and has a large dynamic margin, and the unevenness of the sound field meets the requirements of the first-class standard.
