1. A system for detecting and responding to at least one noise, the system comprising:
a detection unit comprising:
a digital computing device, a digital-to-analog converter, a speaker acoustic output, a microphone acoustic input, an analog-to-digital converter, and a transmitter;the digital-to-analog converter coupled between the digital computing device and the acoustic speaker output;the digital-to-analog converter configured to receive an outbound digital signal from the digital computing device, convert the outbound digital signal to an outbound analog signal, and transmit the outbound analog signal to the speaker acoustic output;the speaker acoustic output configured to receive the outbound analog signal from the digital-to-analog converter and to output an outbound acoustic signal responsive thereto;the microphone acoustic input configured to receive an inbound acoustic signal and to provide an inbound analog signal;the analog-to-digital converter coupled between the microphone acoustic input and the digital computing device;the analog-to-digital converter configured to receive an inbound analog signal from the microphone acoustic input, convert the inbound analog signal to an inbound digital signal, and transmit the inbound digital signal to the digital computing device responsive thereto;the inbound acoustic signal comprising at least one of a reflection of the outbound acoustic signal and a gunshot;the digital computing device coupled to the transmitter;the digital computing device configured to perform an analysis on the inbound digital signal, the analysis to determine at least one of: if the inbound digital signal is consistent with the inbound acoustic signal being a specific noise, and an acoustic mapping of the environment in which the system is located, the digital computing device additionally configured to send a signal to the transmitter if the analysis determines that the inbound digital signal is consistent with the inbound acoustic signal being the specific noise, and to record the acoustic mapping of the environment in which the system is located onto a storage medium,the transmitter configured to transmit a signal via a computer communications network to a host computer system responsive to receiving a signal from the digital computing device. |
