Sound is something most of us take for granted, and rarely do we consider the physics involved. It can come from many sources, a voice, machinery, musical instruments, computers, but all are transmitted the same way: through vibration. Join us to see the many ways NASA is advancing technology and science through supersonic flight. Participants will learn how vibrations from vocal cords react similar to the way shock waves produce a sonic boom and how we are trying to quiet the boom to a "thump."
