Located in Kunshan, China, Duke Kunshan University is a world-class, research-oriented educational institution with a strong focus on liberal arts and sciences. Set within an expansive 80-hectare campus, the university offers a broad spectrum of high-quality and innovative academic programs. It provides an inclusive and multicultural environment for students from around the world, with the objective of nurturing future leaders across disciplines. 

The Duke Kunshan University project is the university’s phase two deployment of an audio-video system. It is a large-scale project that involves the implementation of solutions across 22 buildings, covering 29 classrooms, 20 conference rooms, as well as a visitor’s center. After considering several top global brands, the Duke Kunshan University team headed by chief engineer William Wan selected Sennheiser’s TCC 2, which stood out for its state-of-the-art audio technology, brand-agnostic integration, and proven track record of successful global applications. So far, the university has equipped 50 multifunctional classrooms and spaces with a total of 116 units of Sennheiser TeamConnect Ceiling 2 (TCC 2). These TCC 2s offer an exceptional hybrid learning experience, characterized by superior sound quality and efficient setup.

Hybrid Teaching, Remote Conferencing

The classes at Duke Kunshan University are taught by not only locally based professors but also professors from Duke University in the United States and many others from across the globe. Therefore, one of the school’s requirements for this project was to make sure that all the classrooms could support a hybrid learning experience. The university was especially particular about the audio system; they wanted crystal-clear sound quality delivered by a stable and reliable system, ease of operation, and, last but not least, a flexible system that can be used in different room types, configurations, and learning environments.

TCC 2, equipped with patented dynamic beamforming technology, can automatically identify speakers' positions and seamlessly switch between different speakers in real time, ensuring clear voice capture. Lecturers now have freedom of movement and can interact with students freely. This technology also offers flexibility in arranging classroom layouts, which greatly enhances the learning experience. Its 28 integrated broadcast-level microphone capsules ensure superb speech intelligibility. The remote participants can hear the speakers as if they were in a face-to-face interaction.

In addition to classrooms, Duke Kunshan University also placed a great emphasis on the audio and visual system design and integration in its conference rooms, where virtual meetings are conducted. For this project, the TCC 2 is integrated with the Biamp DSP and the Sony PTZ camera tracking functionality to synchronize the speaker’s location with the cameras. Consequently, real-time camera switching based on speaker changes becomes possible, which delivers a more realistic, efficient, and immersive experience.

Another highlight of this project is the visitor’s center. The university constructed this spacious, 400-square-meter facility to encourage exchanges between professors and students. The center was also designed to be a flexible space that could be configured to serve as an event and exhibition area. For this space, the school wanted not just high-quality audio for conferencing use, but also a system that could elevate in-room audio capabilities. To fulfill this requirement, three units of TCC 2 were installed in the visitors center. The TruVoicelift functionality guarantees that everyone’s voice can be heard clearly from every corner of the room, without any distortion or delays.

Simplified and Brand Agnostic

It took the Duke Kunshan University three years to complete this phase two deployment from design to complete implementation. Besides it being a large-scale project, it is also incredibly complex, since an extensive variety of products from different brands, such as Biamp DSP, Bose speakers, and a Crestron control system had to be integrated. Therefore, seamless product integration at every stage and simplified workflows were crucial. This is also the principal challenge that the team at the Duke Kunshan University faced.

The comprehensive technical and training support that Sennheiser provided contributed greatly to our progress and success in tuning and optimizing the system.

Wan oversaw the audio system design. His team developed a fully digital and distributed AV-over-IP architecture for the campus. Based on Dante, TCC 2 is seamlessly integrated into the campus network, together with audio equipment from various brands. This allows the IT manager to monitor and control a variety of different devices across the campus in real-time, through mobile tablets or desktop devices. This substantially simplifies the workflow, while ensuring reliable performance.

Sennheiser Global Alliances is founded on its brand-agnostic approach, which ensures maximum flexibility for customers. Platform certifications play a crucial role in this approach, as they guarantee seamless interoperability of Sennheiser products with platforms for which they are certified. The TCC 2 is certified for use with numerous mainstream video conferencing platforms, including Microsoft Teams, Zoom, Tencent Meeting, and DingTalk Meeting. This satisfies the diverse preferences and needs of various users.

Customer-Centered Service

Throughout the course of the project, Sennheiser engineers made numerous visits to the site, meticulously working and adjusting room by room to ensure optimal placement and angling of every TCC 2 to achieve the best speech intelligibility. 

“The exceptional quality of the TCC 2 is unquestionable,” Wan remarked. “The Sennheiser team also played a significant role in the successful execution of the project. The comprehensive technical and training support that Sennheiser provided contributed greatly to our progress and success in tuning and optimizing the system.”

Wan continued. “For future development plans, we look forward to continuing working with Sennheiser to further enhance our audio-video facilities, thereby enhancing the immersive learning and collaboration experience for our educators and students.” 

Sennheiser will continue to pay close attention to the evolving trends and shifting requirements of the education sector, and is committed to shaping the future of audio for smart education, with continuous innovation, unparalleled audio products, and cutting-edge technologies.
