Noise Modeling and Impact Analysis from UAS Operations at Grand Forks Air Force Base

HMMH participated in a literature and noise modeling data review for proposed flight operations of Unmanned Aerial Systems (UAS) at Grand Forks, Air Force Base (AFB) in North Dakota. The project determined the applicability and utility of existing US Air Force (Air Force) noise modeling data pertaining to Grand Forks AFB (GFK) and geo-spatial land use data used during previous NEPA or Air Installations Compatible Use Zones (AICUZ) efforts at the installation.

Using the Department of Defense’s (DoD) NOISEMAP (NMAP), HMMH modeled proposed RQ-4 Global Hawk and MQ-1 Predator operations for six simple scaling type of scenarios, computing the Day-Night Average Sound Level (DNL) at noise sensitive receptors closest to the airfield (two residences and daycare facility). HMMH presented its technical approach and results in a series of two Technical Memoranda.
