    Presentation type: oral
    Abstract: The Underwater Sound Reference Division Newport (USRD) was established in Orlando, Florida at the beginning of World War II as the Underwater Sound Reference Laboratory to perform underwater acoustic measurements in support of the United States Navy. Today, the USRD is the U.S. Navy’s primary activity for underwater acoustic calibration, test and evaluation measurements for the full spectrum of underwater systems employed by the U.S Navy, and as well provides acoustic transducer calibration services and evaluations of sonar transducers to private industry, universities and international navies. To support these critical roles, the USRD maintains several world-class facilities, including the Acoustic Pressure Tank Facility (APTF), the Open Tank Facility (OTF), the Low Frequency (LOFAC) and Leesburg Facility (LEFAC). The USRD is the only U.S. activity that runs an underwater transducer standard lease program which develops, manufactures and leases underwater standards to national and international underwater acoustic communities. The presentation will cover facilities and measurement capabilities. The USRD recent ISO 17025 accreditation by the National Voluntary Laboratory Accreditation Program (NVLAP), operated by the U.S. National Institute of Standards and Technology (NIST) will also be discussed, along with current efforts towards eventually becoming a NIST Designated Institute (DI) for underwater sound.
