The weird tool that will tell NASA if the X-59 supersonic jet is truly silent

"NASA scientists are finalizing tests to measure the real impact of the X-59's aerodynamic shape on sonic shockwaves, which are expected to be significantly smaller than traditional sonic booms."

"These shock-sensing probes, adapted from existing designs, will help measure the quieter sonic booms generated by the X-59, enabling calculations of their intensity and propagation."
