ハイドロフォン

HBK hydrophones are individually calibrated, waterborne‐sound transducers. The instruments deliver a flat frequency response and are omnidirectional over a wide frequency range. All hydrophones are built with a shielded-element construction; completely waterproof, corrosion-resistant, and are able to withstand high levels of salinity. The instruments provide unrivaled depth, range, and precision when measuring sound in the lab and in ocean research.

HYDROPHONE SPECIFICATIONS

HBK hydrophones are piezoelectric transducers, designed to be used underwater for recording or listening to underwater sound.

The ceramic piezoelectric sensing element and its internal supporting structure are permanently bonded into sound-transparent, lead-free, nitrile butadiene rubber. Support structures are made from metal alloys that are extremely resistant to corrosion in virtually all hostile environments and have very good anti-fouling properties when immersed in seawater.

The internal support is mechanically and electrically isolated from the metal housing, being coupled only by synthetic rubber. This provides vibration isolation of the sensing element.

RECEIVING SENSITIVITY

Each HBK hydrophone is submitted to an extensive aging and temperature stabilizing procedure before being individually calibrated. Individual calibration data and frequency response curves are supplied with each hydrophone.

The receiving sensitivity calibration of the hydrophones is traceable to international standards.

FREQUENCY RESPONSE

The frequency response of the four hydrophone types is shown here:

Frequency response measurements are made in a water tank in free-field conditions using a Brüel & Kjær PULSE™ calibration system. 

POLAR DIRECTIVITY

HBK Hydrophones deliver great omnidirectional sound measurements. The individual hydrophone directivity patterns in water, are shown here:

The polar directivity patterns were measured in free-field conditions achieved using gating techniques in a water tank. This requires a standard hydrophone as a projector and the unknown hydrophone as the receiver.
