Middle Tennessee State University Upgrades Hybrid Classroom Audio with Sennheiser as “The New Standard” Across Campus

The client

Middle Tennessee State University is a comprehensive university that embraces its role as a preferred destination for Tennessee undergraduates while expanding its reach nationally and internationally through signature programs and select master’s and doctoral programs. With an enrollment of more than 20,000 students, it is the No. 1 producer of graduates for the Greater Nashville economy, has been named to The Princeton Review's list of the Best 388 Colleges in the U.S. four years in a row, and is also the top destination for transfer students in Tennessee.

 

The challenge

After a few years of remote and hybrid classes and leveraging a camera and lanyard-style lavalier microphone for all classrooms, the classroom technology department at Middle Tennessee State University needed a better, easier-to-use solution across campus, with the provision that both the professor and students would be heard in a livestream or recording.

 

The solution

The public university outfitted 250 classrooms with TeamConnect Ceiling 2 microphones to improve audio quality in hybrid classrooms and conference rooms, while streamlining setup for AV staff and educators.

“TeamConnect Ceiling 2 has become the new standard for us. We have four new building projects we are currently designing for, and plan to use them as our microphones.”

James Copeland, Director of Classroom Technology at MTS

Middle Tennessee State University (MTSU) installed 250 Sennheiser TeamConnect Ceiling 2 (TCC2) microphones across campus to streamline their hybrid classroom technology stack while maximizing audio quality for students and faculty. The 500-acre university is home to 20,000 students across 300 degree programs in eight undergraduate colleges, of which an estimated 80% of the student body attend classes in-person. Nevertheless, all classes are recorded and streamed for remote and hybrid participants, making audio quality for all students, interoperability and ease of use for faculty key considerations for the AV and IT staff at the university.

After a few years of remote and hybrid classes and leveraging a camera and lanyard-style lavalier microphone for all classrooms, James Copeland, Director of Classroom Technology at MTSU, realized they needed a better solution. “We quickly felt the pain of using battery powered mics. There were issues with having the batteries regularly charged, so professors would come in and they couldn’t record their lecture because the mic was drained. If a class was over Zoom, the students couldn’t hear anything, so it was like the class wasn’t even happening.” Beyond the challenge of remembering to charge the mic for the next educator, students wanted a better solution for collaboration: “Students in class wanted to communicate with their remote classmates but did not want to physically pass a mic – and potentially germs. Logistically, it was a natural transition to move to a ceiling microphone,” says James.

The classroom technology department needed a better, easier-to-use solution across campus, with the provision that both the professor and students would be heard in a livestream or recording. James and his colleagues Aaron Dill, Classroom Control System Programmer, and Dustin Cunningham, Classroom Audio Visual Technician, landed on the TeamConnect Ceiling 2 for this sizeable project with support from a team of contracted integrators including Howard Technologies, M3, OneDiversified and TriStar Digital Connections.

The choice to go all-in on 250 units of TCC2 across MTSU’s campus was due to several of the mic’s key differentiators. In James’ words, “the Sennheiser option was more ready out of the box [compared to competitors]. What caught my attention was the Priority Zone feature for professors.”

 

Priority Zone For Best-In-Hybrid-Class Audio

The Priority Zone allows users to take full control of the speech in a room by setting a parameter in the space for the audio, enabling it to beam to focus on a specific location, for instance the front of the room around the instructor’s area. This way, if there are side conversations happening across the room, the presenter or professor is not interrupted in the recording or livestream.

Aaron adds, “we have classrooms where the tables and chairs are constantly reoriented. The beamforming mic benefits us here as well, because you never know where everyone will be set up for a class.” The TCC2 features patented dynamic beamforming technology which picks up all audio in a room and uses digital signal processing to automatically locate and highlight the individual speaking, regardless of where they are sitting, standing or moving. Voices are picked up evenly throughout the space, which is an important consideration if planning for a dynamic classroom setup or a professor with a collaborative teaching style.

James and Aaron manage 3000 - 3500 streams each day for class sections, relying on the TCC2s deployed across campus to capture the audio for each of these. They can control the ceiling mics at any time using the Sennheiser Control Cockpit. The TCC2s are integrated with MTSU’s Epiphan Mini video production systems in each classroom as well as their Panopto recording and sharing platform. TCC2 is also certified for Zoom, which is used by a few faculty members as part of their recording setup.

Outside of the classroom use case, the TeamConnect Ceiling 2 microphones are also being used in conference room environments on campus. Specifically, these were selected for audio in the Vice President and Provost’s conference rooms, successfully enabling a natural and flexible audio experience for hybrid meetings happening amongst the university’s leadership and faculty.

 

Resounding Success: MTSU Delights Faculty and Students with Sennheiser TeamConnect Ceiling 2

Since the rollout of the TCC2s across MTSU’s sprawling campus, James and Aaron have received positive feedback from faculty and students. James says, “all I’ve heard is how well it works and how easy it is. I used to get hundreds of tickets that there was no audio in a recording, because faculty would misuse the previous microphone solutions. This is no longer a concern thanks to the ceiling mics.”

Beyond the high-quality recorded audio, students and faculty also enjoy the intuitive mute capability of the TCC2s. James shares, “sometimes students will come up to a professor during class to talk about grades. The ability to easily mute the ceiling mics from the panel for such private conversations was a nice feature.”

In the future, James plans to continue growing MTSU’s state-of-the-art AV and IT setup with Sennheiser. “The TeamConnect Ceiling 2 has become the new standard for us. We have four new building projects we are currently designing for, and plan to use them as our microphones.”
