Abstract: 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 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, may be used to detect gunshots. Other acoustic events such as a patient alarm may also be detected using the system.
