C-Bass

GeoSpectrum’s C-BASS transducers are suitable for a wide variety of very low frequency (VLF) applications including use as calibration sources, active sonar acoustic surveillance, acoustic targets for sonar training and acoustic trials, acoustic communication with ranges exceeding 1,000 km, underwater navigation networks, acoustic thermometry, and diver deterrence. C-BASS also provides broadband coherent acoustic mimicry of anthropogenic noise (i.e. offshore wind, construction, pile driving, etc.)

C-BASS is a novel family of very low frequency (VLF) electrodynamic sound projectors. These powerful electrodynamic projectors are less expensive, lighter, smaller, more efficient, and have a broader bandwidth than their peers. C-BASS makes possible applications that were previously impractical.

GeoSpectrum offers a wide range of standard C-BASS configurations with operating frequencies ranging from below 10 Hz up to 3 kHz and maximum source levels that exceed 200 dB re 1 µPa @ 1m. Our finite element analysis and modeling tools and significant build experience enable us to customize C-Bass designs to customer specifications. The omni-directional C-BASS can be used individually or in arrays to produce high-power sources with or without directivity.

C-BASS are offered as stand-alone transducers for customer integration or as a GeoSpectrum-provided system that can include VLF amplifiers, pressure compensation, signal controllers, tow bodies, deployment cables, and winch systems.
