The Acousonde™ (pronounced ACK-oo-sawnd) is a miniature, self-contained, autonomous acoustic/ultrasonic recorder designed for underwater applications. The Acousonde incorporates hydrophones as well as depth, attitude and orientation sensors, digital recording electronics, data storage, and a field-replaceable battery in a single sealed unit. Applications include:

• Acoustic/behavioral recording tags for marine wildlife
• Highly portable acoustic field recorders
• Autonomous seafloor sound monitors
• Long-baseline acoustic arrays
• Vessel-signature investigations
• Acoustic and attitude/orientation recorders for underwater vehicles
• Temporary attitude/orientation monitors for towed cables

The Acousonde replaces the Bioacoustic Probe, which was discontinued in 2007. Highlights of the design changes can be found in the Frequently-Asked Technical Questions section. Specifications can be found in the PDF brochure located in the Downloads section.

The Acousonde is made by Acoustimetrics, a brand of Greeneridge Sciences, Inc. Development of the Acousonde was made possible by the United States Office of Naval Research.
