What conditions necessitate echo cancelling and noise reduction?
Group and "handsfree" meetings require echo cancellation to prevent the retransmission of sound from a loudspeaker through an open microphone in areas such as meeting rooms and executive offices.
If you prefer not to wear a headset and work hands- free, you require an echo-canceller to prevent your collegues hearing their own voices echoed back from your microphone.
Conferencing microphones are sensitive devices. Effective noise reduction is required to remove unwanted noise from projector and laptop and air-conditioning fans.
