Refer to the exhibit.
Acoustic measurements for ambient noise were taken on a candidate for an Immersive Cisco TelePresence room. The numbers on the floor plan represent the dBA readings for each of the six areas of the room.
Considering Cisco best practices, what can you conclude about the current acoustic situation in the room?
A. Only one area is within the noise levels that are recommended by Cisco.
B. Only one area is not within the noise levels that are recommended by Cisco.
C. All areas are within the noise levels that are recommended by Cisco.
D. Two areas are within the noise levels that are recommended by Cisco.
A is correct. From page 30 of the Telepresence Room Design guide: “…if human speech is 60 to 65 dBA on average, the background sounds should be lower than 40 to 45 dBA”. The front left section is the only one that does not exceed 45 dba of bg noise.
