The BII-7040 series hydrophones provide 60° directivity response approximately at fs resonance, which is designed to detect known sound sources with wide beam angle, and provide omnidirectional directivity response in low frequency range in which the wavelength is much greater than the physical size of the hydrophone. With Hemispherical Hydrophones, noises at certain directions are reduced, ...

BII's piston transducers are made from Tonpilz (Langevin, Sandwich, Transmission Line) elements with features of high power, medium Qm, and low frequency. Custom-fit array can be set up with multiple transducers in field to increase sound level and achieve narrow beam. Some typical transducers are listed below, bespoke transducers with customized resonant frequency fs and radiation area are ...

Manufactured by Benthowave Instrument Inc.based in CANADA
BII's spherical hydrophones provide omnidirectional responses up to 600kHz, and offer excellent acoustic characteristics of low noise and durability, which make these hydrophones ideal for a wide range of oceanography applications. Bespoke built-in preamplifiers allow the hydrophones to be used with long extension cables with no loss in sensitivity. The customized built-in filters increase ...
