Videoconferencing
The
Soundman
system functions as an audio peripheral to a video codec. It may be
easily integrated into a set-top system or enterprise group system for larger rooms. The
added audio functionality does not complicate use of the system. The remote control
supplied with the videoconferencing system controls incoming audio and muting.
Audioconferencing
The Premier telephone interface connects to the SM-02 for audioconferencing
capabilities. The Premier is manufactured by Polycom
modifications for use with the SM-02. The Premier functions as a phone only
(commonly placed on a credenza) and may also be controlled through a wireless remote
offered by CTG. This modified version of the Polycom
through CTG and is designed to function as a permanently installed system.
General Considerations
The Room
Most of today's conference rooms outfitted for teleconferencing will not undergo
improvements for acoustics or noise reduction.
typical conference room with an acoustical drop ceiling. The system includes ceiling
microphones that will be extremely effective in acoustical drop ceilings 10' or lower.
Should there be a condition were the performance of the ceiling microphones would be
compromised, CTG offers a low profile table microphone, or a table implant microphone.
Room Reverberation
Good speech intelligibility is achieved in a room that is not excessively reverberant. An
acoustical drop ceiling in most rooms typically results in clear, intelligible speech being
transmitted to the far end when using ceiling or table microphones. When designing or
renovating a room for teleconferencing, there is an ideal specification for reverberation
time:
Reverberation time is defined as the time that is required for a sound to decay to one-
millionth of its original energy. There are different methods of improving intelligibility
in a poor room:
1. Treat the problem at the source:
• Sound absorbing fiberglass wall panels
• Heavy draperies
• Carpeting
• Acoustical drop ceiling
2. Substitute ceiling microphones with table microphones
3. Relocate microphones – rooms with a raised dome over a conference table will
sound hollow if a ceiling microphone is placed in the dome. Relocating
