Abstract
Forecasting weather and forewarning the public with weather alerts help save lives and property immensely. Audio alert transmissions for weather radio continue to be the most dependable of the multiple techniques used for alerting the public about extreme weather conditions because they are not prone to local infrastructure failure. For a dependable working of this weather alert mechanism, it is important that the weather radio reception should have good clarity of audio. To keep a check on the quality of audio reception, the Mean Opinion Score (MOS) method could be used. It has traditionally been used in telephony quality analysis for decades. However, in case of weather radio, there is no dedicated listener 24/7. The MOS method involves a listener using a scoring system for reporting audio quality. A good MOS method analysis requires an objective skilled listener. Without listening skills and listener training the MOS scoring could be skewed and of little use. If the listener experiences poor audio quality or loss of audio detected at the receive end, steps could be taken to mitigate the situation. Our paper focuses on the design and testing of one such audio-quality forensics system (AQFS) that uses measurements of network, radio and equipment parameters to monitor audio quality. Transmitter stations today have multiple connectivity options and using AQFS as a monitoring system could alert the transmission operators to switch to alternate technology during failures. We have added control features to the AQFS to perform this switching automatically that we have also tested. In this paper, we discuss the design of our system, report our findings and test results.
