5 Acoustic Design Elements for Video/Tele Conferencing Facilities.
Important Acoustic Considerations in Video Conferencing rooms.
- Low background noise levels
- High acoustic seperation between rooms
- Good speech privacy
- Low reverberation times
- High quality speech intelligibility
Video Conferencing is an essential feature in a commercial office fit and acoustics should always be a consideration at the early stage to ensure good speech intelligibility.
The cost for Video Conferencing technology can be substantial however the room can make or break the effective functioning of the system. Think of the room as part of the transmission path from the human speaker to the microphone and from the loudspeaker to our ears.
The manufacturers of conferencing systems specify a reverberation time (RT60) between 0.3s and 0.5s with a noise floor of 30dBA.
Aspects to consider at the design stage.
- Position of the venue in relation to noise sources
- The shape and size of the room
- Walls to underside of the soffit to stop flanking
- Glazing, door and wall detail is important to stop noise and improve privacy
- Keeping building service and mechanical noise as low as possible
- Soft Internal furnishings to help with acoustics
