SYSTEMS AND METHODS FOR SENSING THE OPERATIONAL STATUS OF AN ACOUSTIC HORN

A system for sensing an operational status or level of performance of an acoustic horn makes use of a vibration sensor that is operatively coupled to the driver of the acoustic horn. The sensor can be an accelerometer. The sensor outputs a vibration signal when the acoustic horn is operating. Charac...

Zusammenfassung:	A system for sensing an operational status or level of performance of an acoustic horn makes use of a vibration sensor that is operatively coupled to the driver of the acoustic horn. The sensor can be an accelerometer. The sensor outputs a vibration signal when the acoustic horn is operating. Characteristics of the vibration signal are compared to threshold values or to patterns to determine the operational status or level of performance of the acoustic horn.
