Discussion:
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.

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

No. And maybe. Objectively speaking, individual aircraft flyovers near Sea-Tac Airport are not getting lower or louder. (Before you click away in disgust, note that some of our members live as low as ‘760’, ie. when correcting for sea level less than 400 feet directly under the belly of an aircraft. No one is more
FQUROH: A Flight Demonstration Project for Airframe Noise Reduction Technology – YouTube To make future aircraft quieter, JAXA has been developing airframe noise reduction technologies. The footage introduces JAXA’s FQUROH flight demonstration project for airframe noise reduction technology. (March 2018) (FQUROH stands for the “Flight Demonstration of Quiet Technology to Reduce Noise from High-lift Configurations”)
This is the hardware used for each of the 24 permanent noise monitors around Sea-Tac Airport. The significance for us ‘civilans’ is ...

The summer of 2000 was marked by an unusually high number of aircraft delays, especially at LaGuardia Airport in New York City. These delays continued
