Case Study | Implementation Lessons from the 33-Classroom Upgrade at UCAS

In the rapidly evolving landscape of educational digital transformation, establishing seamless technological systems for large-scale institutions frequently presents significant integration and operational challenges. The recent audio infrastructure upgrade across 33 classrooms at the Yanqi Lake campus of the University of Chinese Academy of Sciences (UCAS) serves as a compelling case study, highlighting the strategic importance of a unified technology architecture.

With three highly distinct learning environments—lecture halls, standard rooms, and interactive classrooms—UCAS faced the complex challenge of meeting strict audio standards for each space without fragmenting their management systems.

1.Rejecting Fragmentation for a Unified Ecosystem

Rather than allocating budget and resources toward three independent systems for the different room types, UCAS opted for a single, adaptable ecosystem utilizing a flexible combination of AISpeech’s ceiling microphone arrays. By integrating the MC10 and MC08 hardware lines, the audio architecture was sharply customized to address the specific dynamics of each spatial scale:

• Lecture Halls (Large Spaces): These expansive environments require broad audio coverage with minimal delay. The deployment of multiple MC10 units—featuring an 8-meter pickup radius, AI-driven noise reduction, and an ultra-low latency of just 25ms—ensured premium audio quality for both local sound reinforcement and clear remote teaching.

  
  

  

• Standard Classrooms (Small Spaces): The solution was optimized through a single MC08 configuration. Boasting a 4.5-meter pickup radius and the capability to automatically filter over 300 types of background noise, this setup enabled standard classrooms to completely eliminate their reliance on traditional handheld microphones.

  
  

  

• Interactive Classrooms (Full Coverage): The dynamic nature of interactive learning demands multi-directional audio capabilities. A combination of the MC08 and MC10 was implemented to provide comprehensive coverage across both instructor and student zones. Notably, this solution allows for the flexible customization of specific pickup zones and silent areas, perfectly supporting multidimensional learning activities.

  
  

  

2.Return on Investment (ROI) and Operational Advantages

The true strength of the UCAS project extends beyond hardware specifications, manifesting clearly in the governance and operational value delivered by the system:

1. Seamless Integration: The new architecture demonstrates seamless compatibility with the institution's existing hardware, including handheld and lapel microphones.

2. All-in-One Functionality: A single, unified platform successfully processes three core tasks of modern teaching spaces: local sound amplification, remote teaching, and lecture recording.

3. Resource Optimization: Standardizing the technology across all 33 diverse educational spaces directly lowered deployment costs while significantly simplifying long-term operations and maintenance.

   
   

Conclusion: The UCAS deployment redefines the standards for audio infrastructure design within large-scale educational and corporate environments. This case study confirms that a flexible technological platform not only resolves the complexities of diverse spatial requirements but also delivers superior administrative efficiency, optimizing both initial capital expenditure and ongoing operational workflows.
