Noise Barrier Study, General Mitchell International Airport

HMMH completed a noise barrier study at General Mitchell International Airport (MKE). The study resulted from a recommendation in MKE’s most recent 14 CFR Part 150 Study to explore the feasibility of noise barriers and other mitigation options for reducing noise from aircraft ground operations on the North and West Ramps in residential areas north of the airfield. HMMH led a team of four firms to complete the study. The study had six major components: inventory of data on current run-up procedures and operations, acoustical sampling, survey of residents and businesses regarding attitudes toward aircraft ground noise and potential mitigation measures including noise barriers, characterization of current ground noise exposure using measurement results and detailed computer modeling using SoundPLAN, identification and cost-benefit evaluation of potential noise remedies including barriers, and evaluation and revision of current run-up procedures documents.

The study resulted in the recommendation of several low-to-no cost measures, including improved aircraft parking locations and orientations, and a revision of run-up procedures to change one of the run-up locations.
