Touchless Audio for Hybrid Learning ADVERTORIAL: AUDIO
discussion, whether located in-class or remotely. For some time now, distance students have become an additional source of income for universities. Offering sophisticated solutions for remote participation will certainly make courses more attractive for them. It provides students with an experience that is much closer to classroom teaching, and fosters a more natural interaction between all participants.
T
eamConnect Ceiling 2 captures audio from socially distanced students and
lecturers for in-room amplification, whilst simultaneously ensuring remote students can hear exactly what’s going on and feel an integral part of the class. In-class, remote, or hybrid learning? The lines
between how students receive information from their educational establishments have become blurred since the pandemic effectively displaced 1.2 billion students from receiving classroom instructions in 2020. With some students joining seminars in person
and others participating virtually via conferencing apps such as Zoom or Microsoft Teams, an effective audio ecosystem is needed which not only links virtual attendees with the lecturer, but also looks at the bigger picture: ensuring quality audio for all in-room participants via a voice lift function, and connecting remote students with their fellow students in the lecture hall or seminar room. Ceiling microphones ensure ‘touchless audio’
through their beamforming microphone array technology. Not only does a ceiling microphone replace handheld or table-top models and contributes to a safe social distance between all on-site participants, who can sit anywhere in the room and get picked up reliably, it also encourages a very natural interaction between physical and virtual participants, making lectures and seminars feel totally lifelike for all involved. The convenience for lecturers should not be
underestimated either. They can simply walk into the room and know that everything works hands- free, without the need to locate a handheld microphone, attach a lapel microphone or stay in front of a tabletop mic. In this context, Sennheiser’s TeamConnect
Ceiling 2 (TCC2) is a particularly appealing solution. Its automatic adaptive beamforming technology follows the active speaker’s voice, allowing them to speak naturally whether they are sitting, standing, or moving around. Classes become totally flexible – it’s no problem to have

more speakers than planned, and interaction in the room is lifelike. This also helps remote participants or distance students to feel an integral part of a seminar. Additionally, TCC2 is fitted with TruVoicelift, a
free feature that ensures clear in-room audio. Thanks to an advanced frequency shift algorithm, TCC2 is able to deliver higher gain before feedback, which can make all the difference to perfectly hearing a speaker. A combination of feedback prevention function, pre-definable audio threshold as well as “advanced exclusion zones” and a “priority zone” ensure a quality listening experience. An open system like TCC2 that can be
integrated with any other ecosystem already in place is also ideal from an installation and IT perspective. Not only does such a system work seamlessly with existing setups, it will still be compatible if the platform is changed. And besides saving additional investments, an open system makes it possible to combine the optimum products for the job at hand. Having Microsoft Teams certification and Zoom certification ensures a TCC2 system can be up and running instantly. Another benefit is the easy configuration of
TCC2 and TruVoicelift via the free Sennheiser Control Cockpit software, which allows microphone settings to be controlled from a central location. TCC2 is compatible with all leading
collaboration ecosystems and video collaboration platforms; via its open protocol, it can be flexibly integrated into any other solution. An attractive option is to use TCC2 for camera control. Here, the advanced real-time positioning data of the ceiling mic is used to capture the video of the active speaker, making hybrid lectures much more engaging and natural for remote participants.
A look into the future Hybrid learning is here to stay, and a combination of ceiling microphone and voice lift system delivers a natural and seamless communication experience between all members of the
