This invention provides a system and method that is used to detect gunfire or explosions in an area with a sound system such as a movie, stage or theater setting, by differentiating the sounds in the presentation from those occurring in the physical location and automatically alerting authorities of

대표청구항 ▼

1. method to detect an event in an area having a broadcasting audio system, wherein a presentation is occurring in the area using the broadcasting audio system; comprising the steps of: positioning a plurality of spaced apart acoustic sensor units in the area to provide an area audio signal;receiving a presentation audio signal directly from an output of the broadcasting audio system at a central processor;separately receiving the area audio signal and the presentation audio signal at the central processor;determining a differential audio data by subtracting the presentation audio signal from the area audio signal; andcomputing if an event is occurring in the area by analyzing the differential audio data for temporal and frequency spectrum content characteristics of the event, wherein the event is a gunshot or an explosion in the area, wherein the area is selected from the group consisting of: movie, stage and theater. 2. The method of claim 1 further comprising the step of notifying a mar management entity Of the event occurring in said area and creating an alarm. 3. The method of claim 2 further comprising the step of cancelling the alarm. 4. The method of claim 2 further comprising the step of cancelling the opening delay of an emergency exit in the area. 5. The method of claim 2 further comprising the step of turning off a sound system in the area. 6. The method of claim 2 further comprising tine step of n notifying law enforcement. 7. The method of claim 2 further comprising the tile step of bringing up lights in the area. 8. The method of claim 1 further comprising the step of logging data related to the event into a data storage system. 9. The method of claim 1 further comprising the step of notifying law enforcement. 10. The method of claim 1 further comprising creating a digitized indicator of a position of the event. 11. The method of claim 1 further comprising the step of deterring a precise time of an arrival of a sound at each of the acoustic sensor units in order to determine the location of the event within the area. 12. A system for generating an alert for an vent in an area with a broadcasting audio system comprising: at least one acoustic sensor unit configured to detect n audio signal of an event within the area;the broadcasting audio system;a central processing unit configured to receive an output from the least one sensor and an output from the audio system, wherein the central processor is configured to compute if the event is occurring in the area by analyzing the differential audio data for temporal and frequency spectrum content characteristics of the event, wherein the event is a gunshot or an explosion in the area and wherein the central data processing unit is configured to determine if the signal corresponding to the audio signal of an event within the area is a false event or is a trigger event; and a system output that causes an external alarm notification, if a trigger event is detected in the area wherein the area is selected from the group consisting of; movie, stage and theater. 13. The system of claim 12 wherein said audio system is configured to create a digitized indicator of a position of the event. 14. The system of claim 12 further comprising a system output to trigger an external alarm notification. 15. The system of claim 12 further comprising an auxiliary input to cancel an alarm via a user action using a remote wired or wireless control if the, alarm is a false alarm. 16. The system of claim 12 further comprising an auxiliary input to trigger an alarm via human action. 17. The system of claim 12 wherein the at least one acoustic sensor unit is comprised of a high sound pressure level electret microphone.
