Project: Farfield Investigation of No Boom Threshold (FaINT)
Like being in the center of a giant orange spider web, a FaINT project researcher connected microphone wiring for a spiral array designed to collect sonic boom data for the project.The test helped to build a dataset that will go toward further understanding of the unique acoustic propagation characteristics near the sonic boom carpet extremity. The FaINT collected finely-space sonic boom data across the entire lateral cutoff transition region. A major objective was to investigate the acoustic phenomena that occur at the audible edge of a sonic boom carpet, including the transition and shadow zones.
