BENTHOWAVE INSTRUMENT INC. Acoustic Transducer & System
High Power Piston Transducer
BII's piston (planar) transducers
are made from Tonpilz (Langevin, Sandwich, Transmission Line)
elements with features of high power, medium Qm, and low frequency.
Custom-fit arrays can be set up with multiple
transducers in field to increase sound levels and achieve narrow beams
or bespoke directivity patterns.
Attenuation/absorption coefficient of sediments is frequency
dependent around 0.06f to 0.6f (dB/(m*kHz)).
