Summary
[edit]| Description |
At Goddard, the engineers use the Acoustic Test Chamber, a 42-foot-tall chamber, with 6-foot-diameter speaker horns to replicate the launch environment. The horns use 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. The 6-foot-wide horns in this 42-foot-tall chamber can produce noise at levels as high as 150 dB. During the acoustics test, the speakers can still be heard outside of its insulated massive metal doors.
