About Is It Quiet?

Why this exists

How loud a place is doesn't show up on a listing or a quick visit. A street can seem calm on a Saturday afternoon and have a jet overhead every two minutes on a weekday morning, depending on the wind and which way the airport is using its runways.

The official noise maps don't help much either. They show a yearly average line, which says little about how many planes pass over, how low they are, or what nights are like. This site counts every flight instead, so you can see what it's actually like to live somewhere: how often, how low, what time of day, and roughly how loud.

It started with aircraft around Philadelphia International and Wilmington. Since September 29, 2026, it covers about 180 km around Philadelphia, from New York to Washington. It's meant for anyone deciding where to live, and for neighbors who want real numbers when they talk to the airport or their representatives.

How it works

• Flights are real positions broadcast by aircraft and collected through the OpenSky Network about every 30 seconds.
• Noise is an estimate from each aircraft type's published noise data and its distance, not a measurement, and usually on the high side.
• A few weeks of data is a small sample. Treat the numbers as a picture of the period shown, not a forecast.
