Summary
[edit]| Description |
Pictured is the James Webb Space Telescope's flight instrument model (ISIM) in the Acoustic Test Chamber at NASA Goddard, about to undergo testing. Note the huge feed horns that reproduce the acoustic environment of a rocket launch. How does this chamber work? It uses an altering flow of gaseous nitrogen to produce a sound level as high as 150 decibels for two-minute tests. That’s about the level of sound heard standing next to a jet engine during takeoff.
