Project: Farfield Investigation of No Boom Threshold (FaINT)
A FaINT project researcher adjusted one of the microphones in a linear array nearly 1-1/2 miles long laid out by the project team to record and measure sonic booms. A major objective of FaINT was to investigate the acoustic phenomena that occur at the audible edge of a sonic boom carpet, including the transition and shadow zones. A NASA F/A-18B aircraft made supersonic passes such that its sonic boom carpet transition zone would intersect a linear 60-microphone, 7500-ft long array.
