Retrieving and Reading the Results of the Noise Level and

Reverberation Tests

After you run the noise level and reverberation tests, you can retrieve the reports by navigating to

Logs > Reports in the Administration GUI. You see a list of .html files whose filenames begin with

Noise and RT60. Click Download to open and view the reports in an HTML browser.

MicBar column (for RT60 and Ambient Noise results): The numbers in MicBar area 1, 2, and 3 refer

to the left, center, and right microphone bars, respectively. If you have a two-row system, 4 to 9 refer

to the second row mic bars, going from left to right.

0.0 result (RT60 reverberation test only): If the RT60 measurement is 0.0, the result was out of

range. This condition can be caused by a high level of noise in the room. Repeating the test should

cause a valid result above 0.0 to appear. If, after rerunning the tests, the results are still 0.0,

reverberation in the room is very high, which will adversely affect the audio quality of TelePresence

calls. Remediation procedures, such as adding an acoustic panel in the room to reduce reverberation

and room noise, might be required.
