Aircraft Noise Contours Noise contours associated with the Dare County Range were developed by the Navy with input from Seymour Johnson AFB as part of the Range Air Installations Compatible Use Zones ( RAICUZ ) Study completed in 2007 . The noise levels were calculated based on mission types and profiles ( average altitude , average thrust setting , and average airspeed ) and delivery profiles including dive bombing , level bombing , pop‐up delivery , and strafing . |

Because of low level flight associated with the DCR , the noise contours extend outside the DCR into Dare , Hyde and Tyrrell Counties at levels between 65 and 75 dB . There is one pocket over the Alligator River where the noise contours are between 70 and 75 dB . Overall , the DCR has a much lower sonic impact on its surrounding communities than Seymour Johnson AFB . The noise contours at the DCR are illustrated on Figure 19 . |
