Mobile acoustic event detection, recognition and location system

1 . A man wearable acoustic sensor comprising:

a housing configured to be man wearable;

a microphone;

a processor housed in said housing, said processor in communication with said microphone to detect an acoustic event and determine a time of arrival for said acoustic event;

a GPS receiver in communication with said processor for providing position information to said processor;

a network interface; and

a display for displaying information concerning said acoustic event to a user.

2 . A portable sensor for detecting and providing a time of arrival of an acoustic event produced in the environment comprising:

a housing configured to be man wearable;

a microphone acoustically coupled to the environment, such that said microphone provides a signal representative of acoustic waves received at said sensor;

a microprocessor housed in said housing, said microprocessor being in electrical communication with said microphone such that a digital representation of said signal is present in said microprocessor;

an absolute time clock in digital communication with said microprocessor such that said microprocessor can obtain synchronized time from said absolute time clock; and

a network interface in digital communication with said microprocessor such that said microprocessor can communicate over a wireless network,

wherein when a predetermined event is received at said microphone, said microprocessor obtains a time of arrival from said absolute time clock and transmits said time of arrival over said wireless network.

3 . A system for detecting acoustic events comprising

a wearable sensor comprising:

a microprocessor;

a microphone communicating with the microprocessor;

a GPS module;

a wireless network system; and

a display screen;

wherein:

the microphone is in communication with the microprocessor allowing the microprocessor to function to detect the acoustic event;

the GPS functions to determine the location of the wearable sensor;

the wireless network system allows for the interfacing and sharing of data between the sensor and other components of the system for detecting acoustic events; and

the system for detecting acoustic events functions to triangulate the location and time of the acoustic event.
