Monitoring > Tunnel Health > MOS > Summary

The Mean Opinion Score (MOS) is a commonly used measure for video, audio, and audiovisual quality evaluation. Perceived quality is rated on a theoretical scale of 1 to 5; the higher the number, the better the quality.


The value can be affected by loss, latency, and jitter. In practice, a value of 4.4 is considered an excellent quality target.
