Underwater Sound Recording and Analysis

The BII-8002 is a portable and advanced sound recorder with the latest laptop technology. It records and analyzes acoustic signals from 10Hz to 3MHz.

Typical signals BII-8002s analyze include Pulsed SINE, Chirp/FM, FSK, natural sounds and marine animal sounds, the signal is processed in time, frequency and time-frequency domain. You may utilize these powerful tools to investigate the signals in detail and to commission the acoustic systems in fields such as noise measurement, bioacoustics, FSK digital communication, echo sounding, sub-bottom profiling, sea-floor mapping, beaconing..., or echos from ultrasonic transducers in air.
