1. An apparatus for identifying acoustic events, comprising:
an electroacoustic transducer configured to identify an acoustic event by airborne sound,
a processor configured to receive the acoustic event and create at least one piece of information that is indicative of the acoustic event or displays the acoustic event, and
a transmitter configured to transmit the at least one piece of information to a terminal to indicate the acoustic event on the terminal,
wherein the processor is configured to break down the acoustic event using a Fourier transformation to obtain a spectrogram and compare the spectrogram with a deposited signal image of a plurality of deposited signal images.
