The Acousonde™ (pronounced ACK-ooo-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. Development of the Acousonde was made possible by the United StatesOffice of Naval Research.
