NASA is about to test ‘quiet’ sonic booms over Texas

If new regulations are written, it could open up a new market for commercial supersonic air travel, according to the statement.

NASA is trying to build a supersonic jet that can break the sound barrier while avoiding ear-splitting sonic booms altogether, Live Science previously reported - but they're not there yet.

"Instead of getting a loud boom-boom, you're going to get at least two quiet thump-thump sounds, if you even hear them at all", Haering said. By using this data, they'll then feed it into their sonic boom-killing research program, one that hopes to design supersonic-but-silent planes.

NASA says that it will continue to carry out testing flights over other US towns in order to gather more ground information; this of course will happen only after Lockheed Martin is able to properly construct the aircraft and NASA is able to establish the proper noise credentials. The goal here is to see if residents find the thumps acceptable.

"This is why the F/A-18 is so important to us as a tool", Haering said.

Park beats Ryu, Hataoko in playoff to win KPMG Women’s PGA
Ryu is playing with plenty of confidence after collecting her first win of 2018 at the Meijer Classic two weeks ago. Ryu got a welcome break at the par five seventh hole when her shot landed in a woman's lunch sack.

There will be audio sensors to provide absolute readings of the sound during the test. however, at least 500 volunteers will provide feedback on what they hear. It's a fluid dynamics thing: When an aircraft traveling through the air - the fluid - moves at increasingly fast speeds, the molecules of air at its nose get increasingly compressed.

An initial test of the research methodology using the F/A-18 was conducted in 2011 with the help of the USA military community that lives on base at Edwards Air Force Base in California.

NASA's team leader for sonic boom community response research at Langley, Alexandra Loubeau, said, "We never know what everyone has heard".

NASA recently awarded Lockheed Martin Aeronautics Company a United States dollars 247.5 million contract to build a faster-than-sound X-plane - official designated X-59 "QueSST" - that will demonstrate quiet supersonic technologies in straight and level flight over a large area. We won't have a noise monitor on their shoulder inside their home.

The practice data recorded at Galveston could begin proving to your principle what the right noise level should be, but it will not be until the X-59 flight is triggered and the final conclusion that does not end your community will be removed. You can hear a double boom at 43 seconds and a thump at 2:34.
