US Patent 10176705 Audio monitoring and sound identification process for remote alarms

In a method for remote monitoring of alarms, an audio test signal is generated by an alarm device while the alarm device is at a particular location and the audio sensors are arranged in a physically separated configuration. The audio test signal is processed to generate alarm identification data that includes data indicative of directionality of the audio test signal. The plurality of audio sensors, arranged in the physically separated configuration, sense an audio signal that the alarm device generated in response to detecting an alarm condition, and the audio signal and directionality data are processed to determine that the alarm device generated the audio signal. A user is caused to be notified that the alarm device was triggered.
