Why Lockheed Martin Is Blasting The Orion Spaceship With 1,500 Speakers

Recommended Posts

That's very interesting......

 

"Seventy to 100 microphones placed on and around the Orion capsule provide feedback, so the engineers know whether the sound waves are diffusing properly".

Lol.  I assume they are using a test signal that has the same spectral characteristics as the launch blast, namely with a lot of bass.  I hope that immediately after each test they play Thus Spake Zarathustra.  That 4 octave bass C chord could grow right out of the test sound.

Very cool, wish they gave a little more detail about amps and power required.

I believe the setup was from Maryland Sound International, it's called DFAT, Direct Field Acoutic Test and is used as an alternative to a full up acoustic test chamber. It can be setup anywhere, it takes amps that come in a tractor trailer rig!

We're talking 140+db over the entire surface of a spacecraft.
