The job of the submarine is to LISTEN, with its sophisticated listenning device, any sound in a wide sound spectrum.
Actually no. Noise is proportional to bandwidth so listening for any sound in a "wide spectrum" is exactly what you shouldn't do. If you know the frequency of the transmitter you should optimise your reciever to that narrow band.
