Cutting Through All the Noise
How the FAA is Working to Reduce the Impact of Aircraft Noise FAA Safety Briefing By Tom Hoffmann, FAA Safety Briefing Managing Editor Growing up in a neighborhood just over a mile north of JFK Airport’s Runway 22R/L, I know a thing or two about aircraft noise. We’re talking about the mid-1970s too, when 707s, -
2021-02-01Dispersion in the Age of RNAV Jim Allerdice, Jr. ABCx2 ANES
A presentation defining aircraft dispersion as a method to introduce track variability and spread out repetitive noise events from highly concentrated flight paths. The document explains why the FAA favors Performance Based Navigation (PBN) for safety, efficiency, and operational benefits. -
Navy should use our data on Growler noise, not dismiss it

The Noise Center
Hear for the Future® The Center for Hearing and Communication is proud to offer the Noise Center as a public service for people seeking information about the dangers of noise exposure and the steps they can take to promote a safer and quieter world. Exposure to noise is the leading cause of hearing loss—not age. -
The impact of noise on childhood cognitive development
Poor classroom acoustics: The invisible reason Johnny can’t read. Poor classroom acoustics create a negative learning environment for many students, especially those with hearing or learning difficulties. According to a report by David Lubman (“America’s Need for Standards and Guidelines to Ensure Satisfactory Classroom Acoustics”) “acoustical conditions in many classrooms are unsuitable for such tasks -
Congressional Quiet Skies Caucus Letter To FAA Administrator Steve Dickson re DNL65
Currently, FAA law has extremely complicated rules for establishing a noise boundary around airports. (A noise boundary is a geographic area inside which there is a certain acceptable noise level.) This is referred to as the DNL65. and it has several major flaws. The FAA Reauthorization Act Of 2018 attempted to address these flaws in several ways. This letter, from a caucus of Congressmen engaged on airport community issues complains to the Administrator that the spirit of the law is not being adhered to and demands that he make attempts to put his agency into compliance. The language is fairly technical, however there are a couple of basic points they raise: First, that the noise boundary be determined by actual noise measurements (currently the noise boundaries are 'modeled' and those calculations often do not reflect in any way the lived experience for residents.) Second, that the 'acceptable' noise level of sixty five decibels (hence DNL65) has been determined to be far too high to conform with current understandings of healthy living. -
New aircraft-noise rule would do little to quiet the skies: government report
By Jon Hemmerdinger 24 August 2020 A ban on aircraft that do not meet new noise standards would do little to reduce overall aircraft noise and would impose costly requirements on airlines and aerospace manufacturers. That is according to a 20 August report from the US Government Accountability Office into the likely impact of a
