Answer: B

Explanation:

A common problem with rooms larger than the Cisco recommended dimensions is excessive reverberation. Large rooms with smooth surface areas such as glass or long parallel walls reflect more sound and in some cases create a noticeable echo, giving the room a ‘boomy’ or ‘echoy’ effect. Additionally, rooms with hard floors or hard-finished ceilings have more reverberation due to the increased hard-surface areas present. Generally reverberation is more of a concern for participants in the room than for the audio being shared with the other side of the Immersive Cisco TelePresence meeting.
