Los Angeles Helicopter Noise Initiative

Helicopter noise is a concern for many residents across Los Angeles County. Since 2012 local community organizations, helicopter operators and other stakeholders have been working with the Federal Aviation Administration in a collaborative process known as the Los Angeles Helicopter Noise Initiative. The participants in the Helicopter Noise Initiative have been working to develop voluntary agreements on routes and altitudes, best practices, outreach and training, and other means of addressing the helicopter noise situation in Los Angeles County.

One of the initial outcomes of this initiative was exploring a centralized complaint system that could serve as a comprehensive repository of helicopter noise complaint data across the county. EMS Brüel & Kjaer, the leading provider of airport noise monitoring systems in the region, developed the ACS to provide helicopter complaint data correlated with flight tracks. The FAA will be obtaining a year’s worth of data from this system. This information will help to identify patterns and trends in helicopter operations, improve our understanding of community reaction to helicopter noise, and inform future efforts to develop and implement noise abatement measures.
