BII-8000 series portable instruments are designed for use in underwater sound synthesis, recording, analysis and playback ranging from 1Hz to 3MHz, and complete with hydrophone, signal conditioning modules, DAQ and notebook computers. With this advanced tool, you may investigate the signal details in time, frequency and time-frequency domain of natural sounds, marine animal sounds, FSK digital communication, echo sounding, sub-bottom profiling, seafloor-mapping , beaconing...

Communication: C = B*log(1+SNR)/log2  bit/s C: Channel Capacity; B: Channel Bandwidth; SNR: Signal-to-Noise Ratio
Echo Sounding: SNR=SL-2TL+TS-NL+AG SL: Source Level; TL: Transmission Loss; TS: Target Strength;
NL: Self-noise Level; AG: Array Gain
