NASA wrote:BOOMS AND WHISPERS – DFRC
NASA’s Dryden Flight Research Center recently completed a research study at Edwards Air Force Base in Southern California designed to gauge public attitudes toward sonic booms.
Pilot Radio.com: “Rolling in 3, 2, 1 now … copy mark.”
The Waveforms and Sonic boom Perception and Response project, WSPR, gathered the reactions of more than 100 volunteer Edwards residents to low-noise booms created by NASA F/A-18 test aircraft.
Michael D. Holtz, Operations Engineer: “With Whisper (WSPR) we’re trying to get a read back from people on the ground to some kind of annoyance level. How annoying was this low boom, how annoying was this moderate boom?”
NASA and industry are working on technology that will reduce the noise and annoyance associated with sonic booms, so they won’t disturb the peace. Aviation and governmental authorities may then consider lifting current prohibitions on aircraft flying over land at supersonic speeds.
Larry Cliatt II, Principal Investigator: “Currently we’re limited by over land sonic booms. There’s no regulation stipulating what kind of sonic booms can be projected over land – right now the rule is no sonic booms over land.
Data from the recent study will be a valuable guide for future public perception studies in communities that normally don’t experience sonic booms.
Larry Cliatt II, Principal Investigator: “People here at the Edwards Air Force Base, they’re obviously very familiar with sonic booms. Eventually we want to take this to a broader level to where people that’s never heard a sonic boom – but we need to figure out how to do that.”
The research was sponsored by the Supersonics Project in NASA's Aeronautics Research Mission Directorate's Fundamental Aeronautics Program.
