Sound Reflecting Surfaces
Windows and other hard surfaces, such as brick, wood paneling, and concrete, are highly reflective and
can cause audio to sound tinny. Consequently, LifeSize recommends that you do not place audio input
devices close to walls or windows. Instead, place such devices in the center of the room and arrange
participants at least four feet away from the input. Clear a radius of 2 feet around the input to minimize
reflectivity. Hang blinds, shades, or curtains from windows to absorb sound and further reduce reflectivity.
Standard office carpeting is also recommended to reduce reverberation, while sound reflective surfaces
like tile and hardwood are not recommended.
Noise Sources
Keep audio input devices away from sources of noise, such as air vents and any components that house
fans or motors. On the HVAC, sound dampening registers and baffles are recommended to help reduce
noise from the flow of air in the ventilation system.
Speakers
Keep speakers and other audio output devices at least 4 feet away from audio input devices.
Audio Coverage
•
LifeSize Digital MicPod has an optimal coverage radius of 12 feet, making it ideal for a room in which
all participants are located within 12 feet of the device (such as a 24 x 24 foot room).
•
For a room that is longer than it is wide, a dual LifeSize Digital MicPod configuration can cover a 20 x
40 foot room. Read

Lighting
LifeSize recommends that you use only one quality of light. For best results, LifeSize recommends that
participants be lit to 350-500 LUX. Overhead fluorescent lights might provide sufficient lighting if they are
concentrated over the conference room table. However, such lights can cause unacceptable shadows if
they are located behind or directly above the participants.
Avoid using natural light, which changes location and intensity throughout the day. It is also recommended
that you avoid mixing daylight with artificial light or mixing different light temperatures.
