[quote=Anonymous][quote=Anonymous]Have a look at the National Transportation Noise Map data which are more recent. Palisades up to W St NW I’d 55-59 dBA 24 hr LAeq, and the rest of the neighborhoods under the flight path are 50-54.9. That’s an average which means that there are many hundreds of much louder planes.

If you look at the combined road and airplane traffic, there are big parts of the Palisades where the average noise is 60-69.9 (such as around Macarthur, Canal, Foxhall). The greatest factor there is the flight path because the houses by the worst of the Connecticut or Wisconsin traffic are at still merely at 50-54.9.

What that doesn’t account for are the noise frequencies - airplanes and revving motorcycles sound much more annoying than cars to most people. Plane noise and frequencies have been shown to affect the body whether you “hear” them or not, including higher blood pressure, stress, inflammation and similar.

DCA # of operations had grown significantly since that time too. And continues to do so.

There are no planes and no noise from about Washington Cathedral, so Woodley Park, Cleveland, Park, DC Chevy Chase.

That’s the data. As I said, anyone measuring morning plane traffic knows very well it’s in the high 60s, 70s and similar.[/quote]

Seems you just don't like the actual data.[/quote]
