BRRC analyzed the potential for damage from sonic boom impacts to Fort Jefferson at Dry Tortuga National Park. Sonic booms are generated by normal training activities within the Key West Range Complex. The assessment involved modeling the current range of sonic booms impacting the area from training operations, measuring the structural response of Fort Jefferson (in coordination with Applied Physical Sciences), and evaluating operational variations that may help to reduce the sonic boom impacts.
NASA Wallops Flight Facility Site Wide Programmatic EIS, VA (Ongoing)
BRRC completed an analysis of the noise from firings of various rocket systems at the Wallops Flight Facility (WFF). This analysis included long-term soundscape monitoring, a traffic noise study, and an assessment of the noise generated from rocket launches. BRRC’s analysis evaluated the potential impacts from rocket launches and demonstrated the contributions of traffic, weather, insects, and human activity on the existing soundscape.
EA for the Transition of E-2C Hawkeye to E-2D Advanced Hawkeye, CA
BRRC conducted noise modeling for the transition of the E-2C Hawkeye to the E-2D Advanced Hawkeye at Naval Station Norfolk, VA (Chambers Field) and Naval Base Ventura County, CA (Pt. Mugu). BRRC reviewed and verified the operational data, and documented the noise impact analysis of these proposed E-2D operations in a technical report. In addition, BRRC assisted in the development of the acoustical sections of the Environmental Assessment (EA).
EIS for Proposed White Elk MOA Extension and Supersonic Airspace, UT and NV
BRRC conducted noise and sonic boom modeling for proposed flight training operations in the proposed extension of White Elk Military Operating Area (MOA) in UT and NV. This analysis involved a review and verification of the operational data for the current and proposed training operations. BRRC documented the analysis in a technical note and assisted in the writing of the noise and sonic boom impact section of the Environmental Impact Statement (EIS).
Developed Operational Descriptions for SUAs and MTRs Above and Surrounding the Townsend Bombing Range (TBR), GA
BRRC developed operational descriptions for Special Use Airspace (SUA) and Military Training Routes (MTR) above and surrounding TBR, and BRRC analyzed aircraft and aerial weaponry noise for a range of potential operational scenarios. This analysis supported the Environmental Impact Statement (EIS) for the proposed modernization and expansion of TBR. The aircraft noise modeled included operations within the entire Coastal MOA complex that surrounds TBR.
