Welcome to The Underwater Sound Reference Division

The Underwater Sound Reference Division (USRD) serves
as the U.S. standardizing activity in the area of underwater acoustic
measurements, as the National Institute
of Standards and Technology (NIST) provides in other areas. The USRD is the
Navy's primary activity for underwater acoustic calibration, test, and
evaluation measurements. In this role the USRD maintains specialized measurement
facilities with the capacity to simulate real-world ocean environments. It also
maintains transducer standards to help ensure the accuracy of measurements made
both at USRD and elsewhere. The USRD supports its facilities and standards with
a robust research and development program dedicated to expanding the
state-of-the-art in underwater acoustic measurements. The USRD is part of the
Sensors and Sonar Systems Department of the
Naval Undersea Warfare Center Division Newport located in Newport, Rhode
Island. It is supported by the Navy's only dedicated research and development
program in underwater acoustic measurements.
