Planning guide for system integrators

Introduction
This document is intended for system integrators and room planners and serves as a planning guide
for installing the TeamConnect Ceiling 2 (TCC2) in a room.
This planning guide contains recommendations for the optimal positioning of one or more TCC2 units
in various room scenarios.
Sennheiser electronic GmbH & Co. KG provides both 2D and 3D CAD files to enable accu-
rate simulation of the coverage area based on the information in this document.
Detailed planning is necessary to ensure that the TCC2 is precisely adapted to the room, even with
the default settings. Using the Control Cockpit software, you can then make manual or automatic
changes to the system settings while the unit is running in order to finely tune it to the specific room
conditions.
This planning guide addresses the following:
• The intended use of the TCC2 device
• Selecting the optimal installation position based on the background noise in the room
• The dimension of the room, based on the floor area
• Basic and alternative options for installing the device in the room
• Installation of the device based on furnishings in the room
• Dealing with potential sources of interference to ensure lossless speech pickup
• The preferred horizontal and vertical alignment of the device to achieve complete three-dimen-
sional coverage of the active zones in the room
• How voice quality is directly affected by the horizontal and vertical alignment of the device in the
room
Intended use
The TCC2 is designed for indoor use and may be used for commercial applications. Typical use
cases include closed rooms for holding lectures, conferences, meetings or other events that involve
both unidirectional and bidirectional speech. The size of the room determines the number of units
required, which you can combine to form a complete system.
The TCC2 is not suitable for use in the music industry or in applications with short or
abrupt speech, such as concerts or musicals.
Requirements for the room
Background noise level
To achieve the best possible speech intelligibility, the level of background noise in the room should
not exceed 45dBA.
As measured by the Speech Transmission Index (STI), the TCC2 achieves a value of 0.79 under these
conditions, which is classified as “excellent” speech intelligibility. The STI is used for acoustic appli-
cations to determine the quality of speech transmission with or without a microphone.
If the reference noise level of 45 dBA is not achieved in a room, you can use the Control Cockpit
software to adjust the room acoustics later while the unit is running. The TCC2 offers settings for
adjusting the “Sensitivity Threshold” and for suppressing elevated background noise during pauses
in speech.
