Here’s everything we know about the sound that rattled windows and shook houses across two states, and the unusual incident that led to it., a sonic boom happens when"shock waves from an object traveling through the air faster than the speed of sound" — or about 750 miles per hour —"merge together before they reach the ground."
And they “generate enormous amounts of sound energy about 110 decibels, like the sound of an explosion or a thunderclap.” That’s precisely what people from Maryland to Virginia said they heard Sunday, with many flocking to social media asking what had happened.Footage from a home security camera in Fairfax Station, Va., posted to social media showed a dog, Rocket, awoken and startled by the sound as he slept on an outdoor deck.

Sonic boom heard over Washington is a rare sound with a rich historyPeople living in and around the nation’s capital experienced a rare, if startling, sound: A sonic boom.

But new companies as well as NASA are working on new technology to reduce sonic booms from supersonic aircraft.
