NASA has announced plans to conduct "quiet supersonic" flight attempts over Galveston, Texas in the coming days. Tests include a pair of F18 jets that will fly over the city next November. During the test, these jets will break the sound barrier up to eight times a day while people are listening on the ground. Finally, the agency plans to inspect hundreds of residents to obtain data on how they perceive the noise levels.
The information comes from local news sources Houston Public Media who report that NASA's plans are not about testing the technology itself, but figuring out how the generated noise is perceived by the local people. Before the tests, the space agency will select 500 people to listen to the flights and later provide information to NASA.
The tests are conducted in November for several days; During this time, NASA will also have noise sensors in the city to collect raw data on the noise level. Residents' responses to the survey are compared to the noise levels detected by the noise sensors. This combination helps NASA develop future technologies that will not disturb nearby populations.
Lockheed Martin quietly develops ultrasound technology in partnership with NASA, and it aims to "reduce a sonic boom to a gentle stroke," according to the company. Lockheed Martin's website states that the Skunk Works has been selected to design, build, and ultimately test the low-boom flight demonstrator that will be used to provide community-response data on the acceptance of technology generated by the technology quiet supersonic bang "to collect.
It looks like supersonic overland travel is banned by existing regulations. NASA intends to set an acceptable supersonic noise standard that will pave the way for the elimination of these regulations. Once the technology is approved for land-based use, a new type of air travel is made possible, reducing the time it takes to reach a destination.
