current technologies and management practices for reducing underwater radiated noise This report, prepared by NCE, provides a comprehensive overview of current technologies and management practices aimed at reducing underwater radiated noise (URN) generated by...
Underwater Noise Monitoring During Marine Construction NCE is providing underwater noise monitoring and assessment services to support the construction of a new dock, bulkhead, and related structures at a federal facility in Rhode Island. Underwater noise monitoring...
Assessment of Underwater Noise From Anthropogenic sources NCE has performed long-range acoustic assessments of many high-energy noise sources for projects around the world. These assessments require the calculation of source levels and acoustic propagation to assess...
Sound Source Verifications NCE has performed sound source verifications on systems ranging from airguns to boomers. Testing was performed using NCE’s Buoy Acoustic Measurement System (BAMS™) to characterize the acoustic output of these sources at close and long...
Washington State Ferries Underwater Noise Study NCE performed an underwater noise study for Washington State Ferries (WSF) which included the measurement of nine vessels representing all seven of WSF’s operating classes. The study quantified noise, potential impacts...
