A method for determining whether a user having a communications device has encountered a perilous situation includes detecting a sound with the communications device and determining whether the sound is indicative of the perilous situation. The method generates a query with the communications device
A method for determining whether a user having a communications device has encountered a perilous situation includes detecting a sound with the communications device and determining whether the sound is indicative of the perilous situation. The method generates a query with the communications device for the user when the sound is determined to be indicative of the perilous situation and waits for a response from the user via the communications device. The response or lack thereof is capable of confirming the perilous situation or a false alarm.

What is claimed is: 1. A method for determining whether a user having a communications device has encountered a perilous situation, the method comprising: detecting a sound with the communications device; determining by the communication device whether said sound is indicative of the perilous situa
What is claimed is: 1. A method for determining whether a user having a communications device has encountered a perilous situation, the method comprising: detecting a sound with the communications device; determining by the communication device whether said sound is indicative of the perilous situation; generating a query of the user soley by the communications device when said sound is determined to be indicative of the perilous situation; querying the user of the communication device for an input to the communication device with a non-audible prompt output by the communication device; receiving an input to the communication device from the user in response to the query; and transmitting a signal from the communications device when the communication device does not receive an input from the user within a period of time after querying the user. 2. The method of claim 1 wherein said sound is determined to be indicative of the perilous situation when the communications device determines a value of an intensity of said sound is greater than an intensity threshold. 3. The method of claim 1 wherein said sound is determined to be indicative of the perilous situation when the communications device determines one of a value of a duration of said sound is less than a duration threshold, whether said sound generally matches a predetermined type of sound, whether a power spectral density of said sound generally matches a predetermined power spectral density, whether a periodicity of said sound generally matches a predetermined periodicity and combinations thereof. 4. The method of claim 1 wherein said query includes one of a voice prompt, a change in tone, a change in vibration, a change in light, a text prompt, a communication from another user, a communication from a situational awareness system and combinations thereof. 5. The method of claim 1 further comprising transmitting a signal from the communications device based on a result of said waiting for said response from the user, wherein said signal includes information selected from a group consisting of a sample of said sound, identifier data associated with the communications device, position information of the communications device, a situational condition based on said response and combinations thereof. 6. A method for determining whether users are in a perilous situation by listening for sounds with communications devices associated with the respective users, the method comprising: determining by the communications device a value of a characteristic descriptive of the sounds detected; comparing said value of said characteristic with a threshold value associated with said characteristic; querying a user of the first communications device with a non-audible prompt output by the first communications device based on said comparing; receiving an input to the first communication device from the user in response to the query, thereby confirming a perilous situation; and transmitting a signal from the first communications device when the first communication device does not receive an input from the user within a period of time after querying the user. 7. The method of claim 6 further comprising receiving a sample of the sounds detected by said first communications device with a second communications device, reviewing said sample of the sounds from said second communications device to confirm the perilous situation or confirm a false alarm and sending said response to said query based on said sample of the sounds. 8. The method of claim 7 wherein said second communications device is associated with a situational awareness system. 9. The method of claim 6 further comprising transmitting a signal from said first communications device based on a result of said waiting for said response or lack thereof, wherein said signal includes information selected from a group consisting of a sample of the sounds, identifier data associated with said first communications device, position information of said first communications device, a battery level, a situational condition based on said response and combinations thereof. 10. The method of claim 6 wherein said determining said value of said characteristic descriptive of the sounds includes one of whether a value of an intensity of the sounds is greater than an intensity threshold, whether a value of a duration of the sounds is less than a duration threshold, whether the sounds generally match predetermined types of sounds, whether a power spectral density of the sounds generally matches a predetermined power spectral density and combinations thereof. 11. The method of claim 6 further comprising determining said threshold value associated with said characteristic by referencing a lookup table, said value based on one of a gunshot, an explosion, an impact, a structural failure and combinations thereof. 12. The method of claim 6 further comprising determining said threshold value associated with said characteristic by referencing a pre-programmed threshold value. 13. The method of claim 6 further comprising listening for sounds from a plurality of communications devices, wherein said plurality of communications devices is capable of being in motion and providing a moving listening array. 14. The method of claim 7 wherein said second communications device controls said first communications device to temporarily listen for the sounds. 15. The method of claim 6 further comprising tracking a plurality of signals received by the communications devices, wherein each of said signals includes position information of a sound of each of said signals and identifier information of said source. 16. The method of claim 14 further comprising deploying personnel based on said tracking of said plurality of signals. 17. A communications device for determining whether a user is in a perilous situation, the communications device comprising: a microphone; an output device; a control module that receives a sound from said microphone and determines whether a value of an intensity of said sound is about greater than an intensity threshold, said control module generates a non-audible query of the user using the output device when said value of said intensity of said sound is greater than said intensity threshold and confirms absence presence of a perilous situation upon receiving an input to the communications device from the user in response to the query; and a transmitter in data communication with the control module that transmits a signal from the device when the user fails to respond to the query within a predetermined period of time after the query. 18. The communications device of claim 17 further comprising an antenna, wherein said control module transmits a signal via said antenna based on a result of said waiting for said response and wherein said signal includes information selected from a group consisting of a portion of said sound, identifier data associated with a source of said signal, position information of said source, a battery level, a situational condition and combinations thereof. 19. The communications device of claim 17 wherein a response to said query originates from one of the user, a situational awareness system that receives said signal, one or more other communications devices that receive said signal and combinations thereof. 20. The method of claim 1 further comprises querying the user with a visual prompt output by the device.
