TruVoicelift TeamConnect Ceiling 2 Room Characteristics While reflections are negligible outdoors due to the distances involved, they must be considered when designing a voice lift system in an enclosed space. Nearly all surfaces have properties that cause them to resonate differently at different frequencies. Depending on the surface, different phenomena can occur, such as reverberation, echo, standing waves, etc. Controlling these phenomena and making them acoustically compatible with the overall system can be a challenge. To achieve the highest possible speech Intelligent beamforming technology utilizes sound wave reflections intelligibility, the background noise level in the room should not exceed 45dBA. Based on the ISL, the distance from the presenter to the farthest listener should be at least 8m (26ft). A voice lift may also be required in smaller rooms, depending on the room acoustics, ambient noise and the presenter's speaking volume. Adaptation to the Room Characteristics with TeamConnect Ceiling 2 The intelligent technology in the TeamConnect Ceiling 2 makes use of the reflective properties of a room. The narrow beam of 30° ensures that excellent speech intelligibility is achieved even in rooms with many reflective surfaces. This focused beam is able to pick up each individual's speech cleanly, even when the presenter is standing with their back to the microphone (e. g. speaking and using a white board at the same time). The „PAG/NAG Calculation" determines the Positioning of the TeamConnect Ceiling 2 optimal loudspeaker positions for achieving the highest possible GBF, depending on the room configuration, ambient noise, and the orientation of the TeamConnect Ceiling 2. This positioning ensures that every listener in the room hears the speaker's natural speech without interference. Rule of thumb We recommend installing the TCC 2 at a height of 3m (10ft) to achieve a coverage radius of 5m (16ft) and a coverage area of approx. 50 to 60m² (approx. 540 to 650 ft2). These values can also be exceeded, depending on the situation. The adjacent illustration shows the relationship between the required speech area and the range of the microphones.
