NASA recently completed a series of tests to reduce risks prior to Phase 2 of its Quesst mission, which will test the ability of the X-59 experimental aircraft to make sonic booms quieter.

In order to measure these very quiet sonic thumps, the ground recording systems used in the CarpetDIEM flights were calibrated to measure as low as about 50 perceived loudness decibels – the equivalent to being in the room with a running refrigerator. Dr. Forrest Carpenter, left, principal investigator for the third phase of CarpetDIEM, Carpet Determination in Entirety Measurements flights, monitors a test from one of the control rooms at NASA’s Armstrong Flight Research Center in Edwards, California. Next to Carpenter is Brian Strovers, chief engineer for Commercial Supersonic Technology.
