the Acoustic Test Chamber at the Jet Propulsion Laboratory

sushi

The Acoustic Test Chamber at the Jet Propulsion Laboratory (JPL) is used to test
various hardware components with a random noise spectrum in order to replicate
a launch environment. The facility currently consists of a WAS 3000 Airstream
Modulator, which is controlled by M+P VibControl Software, and has data
acquisition capabilities of 120 channels.
Requirements can be achieved for a class 10,000 clean room, which includes
garment room and air-shower features. An airlock and clean room hi-bay, located
directly adjacent to the Acoustic Test Chamber, which allows for easy assembly
and inspection procedures.
