Figure 1-4 CTS Device Troubleshooting Window

CTX Tests

The CTX Tests tab provides acoustic tests to determine the acoustic suitability of a room for the installation of a Cisco TelePresence system. You can perform the following acoustic tests:

Reverberation

Noise Level


Note Because the test stops and then starts various services, if you decide to stop the test before it completes, it might take a few minutes before your system is usable. Do not perform any actions on the system while the test is running, and do not switch to another test while the test is running.


Figure 1-5 shows the CTX Tests window.

Figure 1-5 CTX Tests

Reverberation

The reverberation test measures how long it takes for sound waves in the room to decrease by 60 decibels.

When sound waves are generated in an enclosed environment, they continue to reflect from surface to surface until the energy is completely absorbed. This reflection of sound is called reverberation. Reverberation is measured as the rate of time in milliseconds (ms) for sound to decay by 60 decibels (RT60). Ideal conditions for human speech intelligibility are an RT60 value of 300 to 500 milliseconds for all frequencies between 125 Hz and 4 kHz. An extreme in either direction - too much reverberation or too little - can be detrimental to speech intelligibility, and since Cisco TelePresence is generally located in a meeting room in which the human voice is the main source of audio, an ideal sound-quality design preserves the human range of frequencies and isolates this range from interruptions.

For a more thorough discussion of room acoustics and reverberation, and the effect on telepresence conferencing, see the Cisco TelePresence Room Design Guide.

To perform a reverberation test:


Step 1 From left panel of the the CTS Administrative UI, select Troubleshooting > Hardware Setup.

Step 2 Select the CTX Tests tab.

Step 3 Select the Reverberation radio button.

Step 4 Click Start.

The reverberation test will take several minutes to complete. Once complete, the CTS will restart. During the time of the test, and while the CTS is restarting, you will not be able to make telepresence calls.


Note It is important that the room be as silent as possible during the test.



Note The CTS will produce loud tones during while running the test. Cisco recommends exiting the room while the test is running.


After the test is complete, the CTS Administrative UI will display the results of the test, showing the RT60 in milliseconds (ms) at various frequencies. A sample of the test output is below:

Enter Reverberation Test Thu Dec 15 08:36:31 2011
M 125Hz  250Hz   500Hz   1000Hz  2000Hz  4000Hz
1 0.00   360.00  450.00  480.00  420.00  360.00  
 
   

In the above example, a tone at 250 Hz had an RT60 of 360 ms, a tone played at 500 Hz had an RT60 of 450 ms, and so on. If the RT60 ranges for all of the measured frequencies fall between 300 ms and 500 ms, the reverberation in the room is ideal for a Cisco TelePresence system.


Noise Level

The noise level test measures the background noise present in the room. The noise level test measures background noise in decibels with A-weighting (dBA). The Cisco TelePresence system is designed to work in rooms with background noise levels of 45 dBA or lower. Background noise levels above 45 dBA begin to compete with the intelligibility of human speech, and these noises become distracting for participants. Background noise levels over 55 dBA can cause gating or soundsuppression effects in the Cisco TelePresence audio

For a more thorough discussion of room acoustics and noise levels, and the effect on telepresence conferencing, see the Cisco TelePresence Room Design Guide.

To perform a noise level test:


Step 1 From left panel of the the CTS Administrative UI, select Troubleshooting > Hardware Setup.

Step 2 Select the CTX Tests tab.

Step 3 Select the Noise Level radio button.

Step 4 Click Start.

The noise level test will take several minutes to complete. Once complete, the CTS will restart. During the time of the test, and while the CTS is restarting, you will not be able to make telepresence calls.


Note It is important that the room be as silent as possible during the test.



Note The CTS will produce loud tones during while running the test. Cisco recommends exiting the room while the test is running.


After the test is complete, the CTS Administrative UI will display the results of the test, showing the average ambient noise level in decibels, as well as the noise level in decibels at a range of frequencies. A sample of the test output is below:

Enter Noise Level Test Thu Dec 15 08:46:50 2011
M  dBASPL       125Hz   250Hz   500Hz   1000Hz  2000Hz  4000Hz
1  42.06       46.51    41.47   40.73   32.78   26.52   27.63
 
   

In the above example, the average ambient noise was measured at 42.06 dBA (decibels), the ambient noise at 125 Hz was measured at 46.51 dBA, the noise level at 250 Hz was 41.47 dBA, and so on. An average measurement of 45 dBA or lower indicates that the noise levels in this room are acceptable for the installation of a Cisco TelePresence System.
