Underwater sound reference division plus#
Standard quality control allows for a +/- 3dB deviation of nominal sensitivity plus measurement error with compensation for cable attenuation. The preceding specifications were obtained from the average of a limited sample group and were measured at the end of 9-meter cable lengths. Weight (in air): 8g (plus cable 28g/m).Nominal capacitance: 5nF +/- 15% (plus cable 118pF/m).Operating temperature range: -10☌ to +80☌.Vertical Directivity (100kHz): +6dB -11dB.Maximum Input Voltage: 30V p-p (continuous) 150V p-p (Transmitting Sensitivity: 140dB SPL re 1μPa, 1Vrms input at 1meter, 90kHz.Receiving Sensitivity: -208dBV re 1μPa (40μV / Pascal).Use directly with your scope or DAQ device or use with the PA6 preamp and any digital recorder or sound interface for high-quality, low-cost underwater sound analysis.įitted, breathable EVA case included with cable lengths of 20 meters or less (longer cable assemblies will not fit in case and will be bulk shipped in allowable packaging). It can also be used as an omnidirectional reference projector. Given these qualities, the AS-1 is well-suited for absolute underwater sound measurements in marine and industrial environments. Response is omnidirectional in the human auditory bandwidth, as well as omnidirectional in the horizontal axis at all frequencies (theoretical). NUWC’s other division is located in Keyport, Washington.The AS-1 is designed to provide maximum sensitivity in a small size while also providing a linear response in the bandwidth of the highest-quality commercial digital sound recording interfaces. NUWC Division Newport’s mission is to provide research, development, test and evaluation, engineering and fleet support for submarines, autonomous underwater systems, undersea offensive and defensive weapons systems, and countermeasures. NUWC Division Newport, part of the Naval Sea System Command, is one of two divisions of the Naval Undersea Warfare Center. “We look forward to our continued partnership and to identifying new opportunities that serve our state, the U.S. “We are appreciative of the commitment of NUWC Newport to ensure the success of the Innovation Campus” said Dooley. “Once awards are made, NUWC Newport looks forward to working with successful proposers to allow access to our expertise and/or facilities.” Navy’s leading laboratory for the research, development, test, evaluation and fielding undersea systems, NUWC Division Newport would like to express our availability to support responders to the Innovation Campus competition through the Partnership Intermediary Agreement,” said Coughlin. The Innovation Campus is envisioned as a facility designed to stimulate collaborative research and development projects among academic and corporate tenants, with the goals of job growth and catalytic statewide impact. to advance the innovation economy and support the creation of new high-skill jobs. The State of Rhode Island recently established an Innovation Campus competition through URI and the R.I.
The PIA also expands the Division’s reach to small businesses developing technologies of interest to NUWC and the Navy, as well as other academic institutions and non-profits that partner with URI.ĭuring the visit, Coughlin confirmed Division Newport’s support for the newly created R.I. The PIA between the URI BEC and NUWC Newport is designed to increase the likelihood of success in the conduct of cooperative or joint activities with small business firms and institutions of higher education to support strategic efforts in industry engagement, workforce development, and technology-based economic development. national standardizing activity in the area of underwater acoustic measurements. The visit also included a tour of NUWC’s Underwater Sound Reference Division Laboratory, which serves as the U.S. 13 visit built on the existing educational partnership agreement (EPA) with the University and provided an opportunity to discuss new avenues for collaboration under the recent partnership intermediary agreement (PIA) with URI’s Business Engagement Center (URI BEC). Michael Coughlin and other senior leaders to discuss their mutual roles in economic and workforce development. David Dooley visited Naval Undersea Warfare Center (NUWC) Division Newport to meet with Commanding Officer Capt. University of Rhode Island (URI) President Dr.
