Recommendations to improve audio quality
If your laptop is open, position the screen at a 45–degree angle away from the conference phone
or the expansion microphones. Else, the audio will get distorted. Consider the following
recommendations before and during a conference :
• Turn off noisy fans.
• Turn down the volume of mobile devices.
• Do not drum your fingers or tap a pen on the table.
• Turn your laptop screen in a direction that does not obstruct the microphone.
• Do not place papers or folders on top of the extra microphones on the table.
• Do not rest your chin on your hand while talking.
• Close the door or the windows to keep out external sounds.
• Prevent miscellaneous noise by muting the microphone when you are not talking.
Additional audio recommendations
Figure 4: Setting up the conference room
Decorate and furnish the room to reduce reverberation because a cold room causes sound to
bounce around the room. If you are still dissatisfied with the audio quality, consider the following
options:
1. Choose a room where there is no noise from traffic or an air conditioner.
2. Select a room that has wall-to-wall carpeting, which reduces the reverberations.
3. Use long curtains or wall hangings if the room has large windows or a high ceiling.
4. Use potted plants or artificial plants as decorative aids to reduce reverberation.
5. Install sound damping panels if the ceiling is too high.
6. Seek advice from an interior designer to redecorate the conference room.
