Ongoing Research Efforts

 

Airplane

There are many research efforts being conducted on the effects of aviation noise. These efforts are investigating ways to reduce the effects of noise. This section includes just a few examples of the ongoing research.

Continuous Descent Arrival

Check out this video

Continuous Descent Arrival involves the continuous, gradual descent of aircraft on a constant slope at low power. Airframe noise is reduced by the delayed deployment of flaps and landing gear until established on final approach. Instead of using the normal step down approach, the CDA would be a constant descent with reduced power all the way to the airport. This can conserve fuel, limit emissions, and reduce noise during the descent when the airplane is closer to the ground. At 1,000 feet, the aircraft's power is again engaged to land the craft. When permitted by the air traffic control tower, CDA will be used. For more details, see Continuous Descent Approach for additional information on this operation.

Silent Aircraft

Can airplanes be redesigned to be virtually silent? MIT and Cambridge universities are working to create an aircraft that cannot be heard outside the boundaries of airports.

For more details, see Future Outlook: A Quieter Airplane Design

FAA Noise Research Roadmap Workshop

The FAA recently conducted several workshops that brought together researchers, community members, consultants and representatives of government agencies to discuss fundamental topics for the FAA Noise Research Roadmap. The objective was to solicit and discuss ideas and issues that would contribute to noise research objectives. The overall objective for the Research Roadmap is to identify research needs and address the various aspects of the effects of aviation noise impact on members of communities. The FAA wants to identify research efforts that are supported by other agencies, and leverage resources in addition to conducting FAA sponsored research projects.

The research roadmap workshops were initiated after a request from the FAA's Research, Engineering and Development Advisory Committee (REDAC). A preliminary forum was held in conjunction with Internoise 2009 in August 2009, a international meeting for noise researchers. The discussion focused on community annoyance and sleep disturbance due to aviation noise impact.

The first workshop was held December 10-11, 2009, in Washington DC and the second workshop was held in March 4, 2010, in San Diego, CA. Information about the Noise Research Roadmap Workshops can be found at http://fican.org/faaworkshop.html.
